Location for optional attached tape drive (see “Attaching a physical tape drive” on page 29) Figure 1 Front and rear view of the HP D2D Backup System Optional tape attach An Ultrium Tape Drive may be attached directly to the HP D2D Backup System, allowing the user to store backups offsite. An internal tape drive must be half-height and is installed in the half-height bay above the LEDs, labeled 3 on Figure 1. External tape drives may be half-height or full-height. Both SAS and SCSI tape drives are supported and require installation of a host bus adapter (HBA). D2D Backup System 15

www.hp.com/go/connect . Software and hardware requirements Refer to www.hp.com/go/connect for the latest connectivity and compatibility information. • The HP D2D Backup System should be connected to a Gigabit Ethernet network. 100 Base-T Ethernet will limit performance; 10 Base-T Ethernet will severely limit performance. For example network topologies, see “Supported network configurations” on page 24. • For backup and restore you need software that supports tape autoloaders. This software resides on the host, not the HP D2D Backup System. A CD-ROM containing HP Data Protector Express software is supplied with the HP D2D Backup System. The device may also be used with the major backup applications from HP, Symantec, EMC, Computer Associates and others. • Windows Backup is only supported with standalone tape drives created on the HP D2D Backup System. It is not supported for use with autoloader backup devices created on the HP D2D Backup System. Terminology Autoloaders An autoloader is a backup device that has multiple storage slots. Each storage slot contains a cartridge. This has two advantages over standalone tape drives: • The overall storage capacity is much greater. • More importantly, each cartridge can be allocated to a specific backup task; for example, one cartridge can hold Monday’s data, another can hold Tuesday’s data, and so on. In this way, backup applications are able to implement tape rotation strategies that accommodate differing backup requirements for daily, weekly, monthly, yearly backups. Please see “Backup scenarios using the HP D2D Backup System” on page 55 for worked examples. Backup devices and slots Backup devices appear to the host as locally-attached tape devices, but physically, they use disk space on the HP D2D Backup System which, as in tape terminology, is referred to as slots or cartridges. Depending on your data protection strategy, you may configure each backup device as a standalone HP StorageWorks Ultrium Tape Drive or, more typically, as an HP StorageWorks 1x8 G2 Tape Autoloader with attached Ultrium Tape Drive. • When you configure your HP D2D Backup System with a standalone tape drive, 200 GB of physical disk space is made available for that tape drive. This is the equivalent of a permanently- mounted 200 GB tape cartridge, which cannot be unloaded. Tape spanning is impossible, so the data to be backed up must not exceed 200 GB. • When you configure your HP D2D Backup System with a tape autoloader, up to 200 GB of physical disk space can be made available for each configured slot. This is the equivalent of an autoloader with multiple slots, each containing a 200 GB cartridge. Both tape spanning and, more importantly, flexible tape rotation strategies are possible. Hosts Each emulated tape device is uniquely mapped to an individual host; this is the network server or PC that you wish to back up. • The tape device appears to the host as a locally-attached tape autoloader or tape drive. • The tape device is accessed and managed from the backup software running on the host. • The tape device is not visible to other devices on the network. 16 Before you start

Figure 2 on page 17 shows a configuration with a single host. Figure 3 on page 18 shows a configuration with six hosts. See “Connecting and installing the HP D2D Backup System” on page 23 for more example configurations. LAN Host3 Host2 Host4/5/6 Host1 1 2 3 4 5 6 7 8 HP StorageWorks D2D Backup System Autoloader 1 1. The Installation wizard has been run on Host 1. 2. The HP D2D Backup System automatically generates an autoloader for the host. The user may specify the number of slots during installation. Figure 2 Device configuration with one host • By default, the host sees only one device, the autoloader that has been configured for it during installation. Data from each host goes to its corresponding autoloader. • Each backup device is visible only to the host for which it has been configured. • A host may have multiple devices configured for it on the HP D2D Backup System, but this means fewer hosts may be connected (not illustrated, see Figure 34 on page 61 for an example of one host with two devices).

The user may specify the number of slots during installation. Figure 3 Device configuration with multiple hosts Import/Export and Copy If you attach a supported, physical tape drive directly to your HP D2D Backup System, you will be able to copy or export data to the physical tape drive so that backups can be stored offsite. This is an important requirement for Disaster Recovery strategies. The main difference between copy and export is that copied data remains on the HP D2D Backup System; exported data is removed from it, but can be imported easily when required. These functions are grouped under the Tape Attach section of the Web Interface. Please see “Export, import and copy to an attached tape drive” on page 83 for more details about working with Tape Attach. iSCSI The HP D2D Backup System is an iSCSI device. This means that the HP D2D Backup System plugs directly into the network, but it presents devices as directly-attached SCSI autoloaders to host machines. In order to function, it requires an iSCSI initiator. On Windows systems, this is normally downloaded by the Installation wizard, as described in “Connecting and installing the HP D2D Backup System” on page 23. For more information about iSCSI, see “Advanced installation” on page 45. Linux users should also refer to the “Linux Configuration Guide” on the HP StorageWorks Tape CD-ROM for more information. Mail slots (import/export elements) A mail slot is a term borrowed from tape terminology to identify a dedicated slot that is used specifically to import and export cartridges. They are sometimes called import/export elements by backup applications. Backup applications that support this feature move cartridges from the mail slot when the user runs an Export job, and look for cartridges in the mail slot when the user runs an Import job. 18 Before you start

A physical tape drive is a tape drive that is attached to the HP D2D Backup System or the host computer, so that data can be moved from the HP D2D Backup System and stored offsite. (It should not be confused with the tape drive device that can be configured as one of the backup devices on the HP D2D Backup System.) RAID RAID stands for Redundant Array of Inexpensive (or Independent) Devices, which is a data storage scheme that divides data among multiple hard drives, increasing data reliability and throughput. The HP D2D Backup System is a RAID5 device, which offers the best combination of data protection and capacity. It has four hard disks, but if one of the disks fails, no data is lost and the HP D2D Backup System continues to operate correctly. (The failed disk should be replaced as soon as possible, as described in “Replacing the hard disk” on page 115.) Storage capacity Physical storage The physical storage capacity of the HP D2D Backup System 130 is 3.0 TB (3000 GB), of the HP D2D Backup System 120 is 2.0 TB (2000 GB) and of the HP D2D Backup System 110 is 1 TB (1000 GB). However, in order to ensure a high level of data integrity, the disks use RAID 5 protection. This reduces the available capacity but ensures that, in the event of a single disk failure in the device, there will be no data loss. Actual storage capacity is approximately: • 2.25 TB for the HP D2D Backup System 130 • 1.5 TB for the HP D2D Backup System 120 • 750 GB for the HP D2D Backup System 110 You cannot add physical disk space, but you may be able to create some space. Options for creating space, if the disks start to get full, are: • Review your backup jobs to see if you can reduce the size of backup or retention time. • Use the backup application job settings to overwrite or erase data. • Export cartridges to physical tape. Actual storage used The default maximum cartridge size is 200 GB, but the HP D2D Backup System only allocates space as it is required for backup. Individual backup jobs rarely use a whole cartridge and you are unlikely to use all the available disk capacity. However, when configuring the HP D2D Backup System for extremely flexible tape rotation schemes, it may be necessary to exercise a little care. You should take the following factors into consideration to ensure that you do not over-commit physical storage space: • The number of slots that you have configured in an autoloader. The default configuration is 8, but you can edit that to be any number up to 24 (24 x 200 GB = 4.8 TB, which is greater than the physical disk capacity. Therefore, you could not fill all of these slots with the capacity available.) • The number of devices that you have created. It is possible to create up to six tape autoloaders, each with 24 slots. You could not fill all of these slots with the physical disk capacity available. Considerations when configuring cartridges and slots Each slot configured commits 2 GB of physical disk space, regardless of what value has been configured for the maximum cartridge size. The remainder of the configured maximum capacity is used only as needed, but the initial 2 GB is permanently committed. Therefore, only configure the number of slots D2D Backup System 19

committed 192 GB of disk space. Only do this, if you are sure all slots will be used. Once added, slots cannot be removed. 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 1. 8 x 2 GB of physical disk space has been committed. 2. The remainder of the configured maximum capacity is used only as needed, but the initial 2 GB is permanently committed. Figure 4 Storage capacity The example configurations in “Backup scenarios using the HP D2D Backup System” on page 55 illustrate how you can make full use of the available slots in designing your backup rotation strategy and ensure that you do not create a backup scheme that would result in running out of physical disk space. NOTE: The LED indicators and the Status pages on the Web Management Interface will warn you when disks in the HP D2D Backup System exceed 90% full. Tape rotation strategies Tape rotation strategies determine when backups are run, the number of cartridges that are required and how they are reused. The HP D2D Backup System is a very flexible device that can easily be incorporated into most tape rotation strategies. If your organization does not yet have a tape rotation strategy in place, see “Backup scenarios using the HP D2D Backup System” on page 55 for example configurations. 20 Before you start

moving data from the HP D2D to physical tape, bear in mind that HP StorageWorks tape drives do apply compression. Therefore, 200 GB of data on the HP D2D Backup System will require less space on a physical tape cartridge. If moving data to a physical cartridge for offsite storage, there is no need for concern if the data seems to utilize less space. Some users may choose to enable software compression from their backup application to increase the storage space available to the backup application, but this can make backup jobs slower to run. However, once software compression has been applied, the data is not further compressed when it is exported to a physical tape directly attached to the HP D2D Backup System. This ensures that the user knows exactly how much physical cartridge space is required for export or copy. D2D Backup System 21

Network connector 2. Power connector Figure 5 Network and power connectors 1. Always use the supplied power cord to connect the HP D2D Backup System to the main power supply. This HP-approved cord is appropriate for your specific geographic region. For detailed safety information, see the Safety Guide on the HP StorageWorks CD-ROM. 2. Use the supplied network cable to connect to a Gigabit network switch. 100 Base-T Ethernet will limit performance; 10 Base-T Ethernet will severely limit performance. For example network topologies, see “Supported network configurations” on page 24. D2D Backup System 23

DHCP network addressing is enabled by default, which means that an IP address and other network settings are assigned automatically when you connect the HP D2D Backup System to a network that has a DHCP server. If preferred, you can use static IP addressing and assign settings manually during the installation process. In both instances, the HP D2D Backup System should be on the same logical and physical network as the host machine connecting to it. This is normally the case because, typically, the HP D2D Backup System is connected to the same Gigabit network switch as the host machines backing up to it. Optional Tape Attach A tape drive may be attached directly to your HP D2D Backup System, allowing you to store backups offsite. Please refer to “Attaching a physical tape drive” on page 29 for further details. Figure 6 Attaching a tape drive to the HP D2D Backup System 1. Internal tape drive 2. External tape drive Supported network configurations There are two ways of connecting the HP D2D Backup System to your network: • By connecting it directly to a network switch on your network • By connecting it to a backup server that is already on the network As a device on a Gigabit Ethernet network The HP D2D Backup System is connected to a spare port on an existing Gigabit network switch. This may be your main network, which is also used to connect a number of different types of devices, such as PCs, servers, workstations and printers, or a dedicated backup network that is used solely for clients that need to be backed up. The configuration, illustrated in Figure 7 on page 25, is the simplest and most common configuration, assuming that Gigabit networking is already in place, and requires no additional hardware. The only disadvantage to the configuration is that a high volume of traffic may impact network performance during backup and backups may take longer to complete. However, if backups are scheduled to run outside of normal business hours, the volume of data traffic is unlikely to be a problem. 24 Connecting and installing the HP D2D Backup System

Backup System LAN Switch Server PC Server Supplied cable Figure 7 Connecting to a business server on the main network In some environments, backup data is kept separate from day-to-day office network traffic, as illustrated in Figure 8 on page 25. There is a separate, dedicated IP network for all hosts that need data to be backed up. HP StorageWorks D2D Backup System Storage Network LAN Switch Server PC Server Supplied cable Figure 8 Connecting to a dedicated backup network NOTE: Our example shows one PC that is connected to the LAN, but not to the Storage Network. This PC will not be able to run the Installation wizard or connect to the HP D2D Backup System from the web. No data from this PC can be directly backed up to the HP D2D Backup System. Directly connected to a backup server on your main network In this configuration, a specific server on the network is being used as a backup server. The HP D2D Backup System has a dedicated connection directly to the storage server and not to the business network. D2D Backup System 25

devices on the network must be configured as clients that back up to the designated backup server over the business network, which may impact performance. HP StorageWorks D2D Backup System LAN Switch Server Server PC Storage Server Supplied cable Figure 9 Connecting to a network server This configuration, illustrated in Figure 9 on page 26, requires a spare Gigabit network port or card on the storage server to support the direct connection to the HP D2D Backup System. Use the cable supplied with the HP D2D Backup System to connect to the Gigabit network card on the server. NOTE: If the server has a 10/100 Base-T network card, you will need a cross-over network cable (not supplied). A better solution, to ensure optimum performance, is to purchase and install a Gigabit network card. Software installation, discovery and configuration There are three stages to installation: • Install all the required drivers • Discover the HP D2D Backup System on the network, give it a name and, if DHCP is not supported, assign network settings • Create a base configuration to get started Dynamic (DHCP) addressing is enabled by default on the HP D2D Backup System. If your network supports DHCP, all the required network parameters will be assigned automatically. If your network uses static IP addressing, you will need to assign network settings manually (IP address, subnet mask and gateway). For Windows users, the recommended way to set up the HP D2D Backup System network is to run the Installation wizard from the HP StorageWorks CD-ROM, as described in “Installation wizard” on page 39. Linux users should download the latest patches for their operating system and refer to the “Linux Configuration Guide” on the HP StorageWorks CD-ROM for configuration instructions.

This chapter is relevant for users installing on a Windows host. If you are installing on a Linux system, please refer to the “Linux Configuration Guide” on the HP StorageWorks Tape CD-ROM. In this chapter: • “Before you install the first host” on page 39 • “Run the Installation wizard” on page 40 If you are installing on a Windows system, the Installation wizard is the recommended way to set up a host machine to work with the HP D2D Backup System, particularly if you are configuring the host for the first time. The wizard automatically configures all the software components needed to connect and use the HP D2D Backup System. It should be run on all hosts that are to be backed up to the HP D2D Backup System. If you are not using the Installation wizard to install on a Windows system, please see “Advanced installation” on page 45. Before you install the first host You must have the necessary administrative rights on the host to run the Installation wizard successfully. 1. Make sure the host machine on which you are running the Installation wizard has Internet access. If it does not, you will have to download the Microsoft ® iSCSI Initiator manually. See “Microsoft iSCSI Initiator” on page 46. 2. Press the Power on button on the front of your HP D2D Backup System. During power on the LEDs will perform a self-test sequence; all LEDs with the exception of the status LED will then be extinguished until the boot sequence is completed. D2D Backup System 39

Figure 25 Powering on the HP D2D Backup System Run the Installation wizard The HP D2D Backup System can be used to back up a maximum of six hosts. You should run the Installation wizard on each host that will provide a source of data for backup. The host may be a server, workstation or PC. 1. Insert the CD-ROM supplied with your HP D2D Backup System into the host machine. It should launch automatically. If it does not, locate the D2DInstallationWizard.exe file and run it manually. 2. Select Start the wizard and follow the onscreen instructions to step through the installation, normally by pressing Next. The Installation wizard will automatically configure all the software components required for setup and use of the HP D2D Backup System. There are three main phases: • Install the tape drivers: These allow your system to recognize the tape drives created on the HP D2D Backup System. 40 The Installation wizard

configure network settings. If you have multiple devices on your network, a list is displayed so that you can select the required HP D2D Backup System. The configuration page for the device is displayed. DHCP is enabled by default. If you wish to use static IP addressing, disable DHCP and enter the IP address details. D2D Backup System 41

to physically identify a D2D device. Use Beacon mode to flash the LEDs on the selected device. • iSCSI installation and configuration: If required, this step retrieves and installs the Microsoft iSCSI initiator, connects this host to the HP D2D Backup System and configures an autoloader, as defined by the user. The second option presented in this dialog is appropriate for most backup applications and is the recommended option. You may edit the number of slots, if required. 42 The Installation wizard

3. The Installation wizard sets up a link to the Web Management Interface on the host’s desktop and gives you the option of launching it. Once it has been assigned network settings, the HP D2D Backup System is ready to use. See “The Web Management Interface ” on page 63. The HP D2D Backup System does not appear as a device under My Computer and it is not mapped to a drive letter (although it can be seen as a tape drive (1) and medium changer (2) from Device Manager). Use a backup application on the host machine to back up and restore data. 4. Run the Installation wizard on any other hosts that are to be backed up—six is the maximum. On running the wizard on subsequent hosts, you only need to select the HP D2D Backup System; its network settings have already been assigned. D2D Backup System 43

Although the Installation wizard is the recommended way to install the HP D2D Backup System, it is possible to install it manually. You may also need to run phases independently when troubleshooting. This chapter describes: • “Using DHCP to discover the HP D2D” on page 45 • “Using the Discovery Engine to discover the HP D2D” on page 45 • “Microsoft iSCSI Initiator” on page 46 • “Linux iSCSI initiator” on page 51 • “Manual driver installation” on page 51 Using DHCP to discover the HP D2D Backup System If you are connecting the HP D2D Backup System to a network that has a DHCP server, DHCP addressing is enabled by default. The IP address and other network settings are assigned automatically when you connect the HP D2D Backup System to the network. You only need to know the name of the HP D2D Backup System to complete the installation and create an 8–slot autoloader configuration. The name is in the format D2DBS- and can be found on the label on the front of the unit. In the web browser type in: D2DBS- NOTE: Depending on network settings, you may need to enter the full domain path. Once the HP D2D Backup System has been discovered on the network, you must configure the Microsoft iSCSI Initiator on the host, so that the autoloader devices on the HP D2D are visible to the backup application. See “Microsoft iSCSI Initiator” on page 46. Using the Discovery Engine to discover the HP D2D Backup System If your network does not have a DHCP server, the Discovery Engine allows you to locate the HP D2D Backup System on your network and assign network settings, such as the IP address. It is the recommended way to locate and configure the HP D2D Backup System on your network, if you are using static IP addressing. It also allows you to select your required base configuration and specify the number of slots for an autoloader. The Discovery Engine can be run as part of the Installation wizard or as a standalone utility from the HP StorageWorks Tape CD-ROM. D2D Backup System 45

being configured, if several are connected to the network. See also “LEDs ” on page 53. If the HP D2D Backup System is new and not yet configured When installing the HP D2D Backup System for the first time, this step must be completed successfully before you can connect from your host. Select the appropriate HP D2D Backup System from the list and make a note of its IP address because you will need this when you configure the Microsoft iSCSI Initiator, see “Discovery tab” on page 48. If the HP D2D Backup System has been configured incorrectly If you cannot connect to the HP D2D Backup System using the Web Management interface, it may have been configured incorrectly. Run the Discovery Engine to check the IP address of the HP D2D Backup System and, if necessary, select it again from the list of available HP D2D Backup Systems. If you still cannot connect to it, check that you have configured the Microsoft iSCSI Initiator correctly, see “Discovery tab” on page 48. If the network setup has been changed If the network infrastructure changes, you may need to update the HP D2D Backup System network settings to allow hosts to continue to connect. Run the Discovery Engine and change the network settings in accordance with your new infrastructure. You can also use the Web Management Interface to modify these settings directly on the HP D2D Backup System, as long as this is done before the infrastructure changes are made. Once the network settings of the HP D2D Backup System have been changed, you must also change the Microsoft iSCSI Initiator for each host. Microsoft iSCSI Initiator iSCSI is a protocol for sending SCSI commands via Ethernet. It defines how SCSI packets are translated to Ethernet packets and connects to the required devices. An iSCSI initiator may be hardware or software. The HP D2D Backup System supports the Microsoft software iSCSI initiator and requires it to be running 46 Advanced installation

autoloader (or tape drive) configured on HP D2D Backup System and will not be able to perform backups. The Microsoft iSCSI initiator must be retrieved from the Microsoft website. Figure 27 iSCSI Initiator download page 1, amd 64 Use with amd ® 64-bit processors and with Intel ® em64t processors, when running a 64-bit version of the Windows operating system. 2, ia 64 Use with ia-64 processors, such as Itanium and HP Integrity. 3, x86 Use with 32-bit processors or 64-bit processors running 32-bit Windows, such as Windows XP and Server 2003. If you download the wrong version, it will not install. The simplest way of ensuring you download the correct version is to run the Installation wizard from the HP StorageWorks CD-ROM because it automatically checks which is the appropriate version for your host. NOTE: The Microsoft Vista operating system includes the Microsoft iSCSI Initiator. It can be run from the Control Panel in Classic Mode. Manual iSCSI initiator installation The Installation wizard could fail for the following reasons: • The host machine does not have an internet connection • Firewall restrictions prevent this process • Microsoft has relocated the iSCSI initiator files to a different address on its website. • The process times out due to a slow connection If the process fails: 1. On a machine that supports an external internet connection, go to the Microsoft website and search on "iSCSI initiator" 2. Select the result that takes you to the Download page and choose the download that is appropriate for your host. 3. Download the iSCSI initiator and install it on the host, accepting all the default settings. The iSCSI Initiator The Microsoft iSCSI initiator contains a number of tabs. This section describes the information that must be provided in order to connect the host to a device on the HP D2D Backup System. It does not provide a comprehensive description of all the tabs; please download the “User Guide” from the Microsoft website for more information. D2D Backup System 47

generated automatically, which guarantees that it will be unique on your network. The other fields relate to authentication and are not needed for the HP D2D Backup System. Only use them if required to by your IT policy. (If you use Secret to enter an encryption string in this dialog to authenticate targets, you must also enter the same string on the Web Management interface in the iSCSI page. (See “iSCSI (Status)” on page 77.) NOTE: When you use the Web Management Interface to create an additional device for your host, you must provide the iSCSI Initiator Name. This is the Initiator Node Name found on the General tab. Discovery tab You must enter the IP address or fully qualified domain name of the HP D2D Backup System (for example, myhpd2d.mydomain.com) to add it as a target portal for the host on the Discovery tab. Do not change the Port; it should be 3260. 48 Advanced installation

not been run, it will automatically create an 8-slot autoloader with two target devices (loader and tape drive). • If target devices have already been configured for the host in the past, they appear in the list; no more are created. Targets tab This tab contains a list of all available devices. When you run the iSCSI Initiator manually, new devices have a status of Inactive. You must log on to the appropriate targets for your host. Remember that each autoloader has two devices and you must log onto each one separately. D2D Backup System 49

option in the Log On dialog. Persistent Targets tab The Persistent Targets tab shows the targets that have been configured to restore automatically on reboot. During initial configuration, it is for information only. However, if you want to stop the host automatically connecting to a device, you must select the device on this tab and Remove it. To disconnect the device without rebooting, go back to the Targets tab, select the device, click Details and log off. 50 Advanced installation

No configuration is required on the Bound Volumes/Devices tab. Linux iSCSI initiator An iSCSI initiator is embedded in the operating system. Please refer to the “Linux Configuration Guide” on the HP StorageWorks Tape CD-ROM for instructions on using it. Make sure that you have downloaded the latest operating system patches before you configure your system. Manual driver installation Two drivers are required; an HP LTO Tape driver and a medium changer driver. NOTE: Certain backup applications require you to use their own drivers for both the tape device and medium changer. For many applications these will be installed automatically during the software installation process. If the backup software is already installed, you may need to manually update the drivers after installing the HP D2D Backup System. D2D Backup System 51

The HP LTO Tape driver must be installed to allow your system to recognize the Ultrium devices created by the HP D2D Backup System. Tape drivers can be installed from the drivers directory on the HP StorageWorks CD-ROM, where they are supplied as an installer application and as driver files for manual installation. Also check the HP website for driver updates at www.hp.com/support. The tape drive is reported to your backup application (and Windows Device Manager) as an LTO-3 device. This is the default behavior of the tape drive and there is no need and no way to change it on the HP D2D Backup System. It is important not to confuse emulation type with cartridge size. Emulation type is totally independent from cartridge size. The HP D2D Backup System allows you to pick whatever cartridge size you like (up to 800 GB). In earlier versions of the HP D2D Backup System firmware, the tape drive was reported as an LTO-2 device. Once you upgrade to the latest version of the firmware, the backup application continues to identify existing backup devices as LTO-2 and identifies new tape devices as LTO-3, but this has absolutely no impact on how the device behaves or functions. If you delete existing devices (LTO-2) and create new ones; the new ones will be LTO-3. Medium changer driver No additional medium changer driver is required because Microsoft Windows provides a suitable generic driver and all backup applications provide their own changer drivers. 52 Advanced installation

D2D Backup System The HP D2D Backup System combines all the traditional benefits of tape technology, such as support for complex media rotation schemes, with the rapid backup and restore time that is only possible from disk. Backup applications allow users to configure rotation schemes that use tapes for specific days, weeks and months of a year, often applying different retention policies to each backup job. Such rotation schemes require an autoloader as the backup device. Using a tape autoloader configured on your HP D2D Backup System enables you to use the same tape rotation schemes that you would use with physical tape. To your backup application the tape autoloader configured on the HP D2D Backup System is a physical tape autoloader device and you can configure backup jobs from your backup application in exactly the same way as you would for tape. But you benefit from much faster performance because you are writing to or reading from disk. Read this chapter for example backup scenarios. It will also give you a clearer understanding of how you can calculate the number of slots required and ensure that disk space is used effectively. • “Example 1: Simple backup” on page 55 • “Example 2: Office backup” on page 56 • “Example 3: High-performance workstation” on page 60 • “Incorporating archive to tape into a rotation strategy” on page 61 Simple backup • On Friday: carry out a full backup to one cartridge to capture the week’s work and keep that cartridge for four weeks before overwriting. Assuming a separate cartridge for each week’s full backup, four autoloader slots are required. • For the other weekdays, Monday to Thursday: carry out incremental backups to capture that day’s changes (one cartridge for each day) and keep each cartridge for a week before overwriting. Assuming a separate cartridge for each day’s incremental backup, another four autoloader slots are required. • On Friday overnight: run a copy job to copy Friday’s full backup to physical tape for offsite storage. D2D Backup System 55

Tape Drive Figure 29 Simple backup from a single host This scenario provides fast restore times for individual files, with the added security of offsite tape storage. It requires 8 autoloader slots. The examples in the rest of this chapter illustrate more complex scenarios. Office backup The office has three hosts that must be backed up: • A fileserver • A Database server • A high-performance desktop PC Each device will be backed up to an autoloader on the HP D2D Backup System. You must run the Installation wizard on each host that is to be backed up. The following examples illustrate how you decide how many slots should be allocated to each autoloader. You can either assign these during installation, if you run the Installation wizard, or use the Web Management interface after installation to increase the number of slots, as described in “To edit device details” on page 66. Fileserver This is used by all the people in the office who have access to a file share on the server for storing office documents, such as word processing files and spreadsheets. These files must be backed up daily, retained for a month and copied once a week to a tape drive attached to the fileserver for offsite storage. The starting size of the data on the file share is 60 GB. Daily changes are approximately 500 MB.

This data will be backed up to an autoloader configured on the HP D2D Backup System. Additionally, there is an ‘IMPORTANT’ folder that relates to current, high-priority projects that must be backed up daily and moved from the HP D2D to physical tape at the end of each week. This data will be backed up to a standalone tape drive configured on the HP D2D Backup System. You can specify the number of slots to meet the backup requirements for the workstation when you run the Installation wizard, or from the Web Management interface after installation. You must use the Devices page of the Web Management interface to create an additional standalone tape drive device for the ‘IMPORTANT’ folder. (See “To create a new device” on page 66 for further details.) Main backup to autoloader The data at 250 GB exceeds the disk space that can be allocated to a single slot. Therefore, each full backup requires two autoloader slots. You must also make sure that tape spanning is enabled in your backup application.

Incorporating archive to tape into a rotation strategy Two methods are provided for archive a cartridge to the directly attached tape device, these are Copy and Export. • Copy retains the data cartridge on the HP D2D system and creates an exact copy onto a physical cartridge in the attached tape drive. • Export removes the data cartridge from the autoloader on the D2D once data has been successfully copied to the physical cartridge in the attached tape drive. Each method has advantages and disadvantages, as described in more detail in “Archiving methods” on page 84. Refer also to the white papers on httP://www.hp.com/support for examples of using these functions with specific backup applications. This example shows how to incorporate copy to a tape drive connected to the HP D2D Backup System into a tape rotation strategy. • On Friday: carry out a full backup to one cartridge to capture the week’s work and keep that cartridge for four weeks before overwriting. Assuming a separate cartridge for each week’s full backup, four autoloader slots are required. D2D Backup System 61

changes (one cartridge for each day) and keep each cartridge for a week before overwriting. Assuming a separate cartridge for each day’s incremental backup, another four autoloader slots are required. • On the last day of the month: • From the host (1) carry out a full backup to one cartridge to capture the month’s work ready for archiving, this requires one extra slot on the autoloader device (2) • From the HP D2D Web interface schedule a copy to physical cartridge job (3) to run on the last day of the month. See “Cartridge copy” on page 84 for further details. Figure 35 Copying to physical tape as part of a rotation strategy This scenario requires nine slots on the autoloader device and a physical cartridge in the attached tape drive on the last day of the month. The cartridge data remains on both the HP D2D Backup System and the copy on the physical tape drive can be stored offsite. 62 Backup scenarios using the HP D2D Backup System

The Web Management Interface is the main interface for: • Monitoring the status and health of the HP D2D Backup System and all configured backup devices • Changing the number of cartridge slots or creating additional autoloaders, or standalone tape drives, for a host • Managing movement of data to and from a physical tape drive attached to the HP D2D (if one has been installed) To run the Web Management Interface There are two ways of logging on: • From the host server or PC: Use the desktop shortcut created by the Installation wizard. • From any machine connected to the network: Enter the IP address or fully qualified domain name (for example, myhpd2d.mydomain.com) of the HP D2D Backup System into the web browser. The Web Management Interface displays the Login prompt: The Login is Administrator with an initial password of Admin. Both names are case sensitive. The password can subsequently be changed from the Administration menu option, see “Administration (Admin)” on page 80. D2D Backup System 63

JAVA scripting enabled. If it does not, some of the browser buttons may not be displayed. See “Web browser settings” on page 26. Summary (Home) Whenever you log in, the Summary page is displayed. Use this page: • To display information about your HP D2D Backup System and the backup devices that have been configured for it. • To monitor system health and status. • To display status information about any physical tape drives that are attached directly to the D2D Backup System. 64 The Web Management Interface

1 Navigation bar Select the appropriate option from the side bar. 2 Help and logout The Help option opens the help pages. Logout closes your session on the HP D2D Backup System. If somebody else logs in, you will be automatically logged out. 3 Device information This section provides the information that identifies your HP D2D Backup System. It shows the IP Address and Network Name of the HP D2D Backup System. 4 Status details This section provides details about overall system status and the status of system components. Additional information is provided if the status is not OK. See also “Status icons” on page 65. Network, Disk Usage and RAID all link directly to the relevant pages for more information. If a tape drive is connected directly to the HP D2D Backup System, its status is also displayed in this section with a link to job history. 5 Configured backup devices This section shows the devices that have been configured and their connection status. Our example shows one autoloader and no tape drives. Note that when a tape drive is shown, it is the tape drive that has been configured on the HP D2D Backup System and not the physical tape drive that may be attached to it. The icon for the device changes to indicate a copy or export to physical tape by showing the cartridge partially ejected. To configure the devices, select Devices from the navigation side bar. Or: • Click on the relevant Edit Config, iSCSI or Cartridges link to view specific information for the selected device. Status icons Indicates a healthy system or system component. Indicates a warning or error state. Devices (Configuration) By default, one autoloader is created automatically when a new host connects to the HP D2D Backup System. Use this page to view and configure the default autoloader and to create additional devices, if required, for the host. The top half of the page shows the six possible devices available on the HP D2D Backup System. None or all of these may be populated depending on how many devices have been created. To view device details Click on Select to view the details for a selected device in the bottom half of the page, where you can also edit and delete details. There are also links on the Name, Cartridges and Connection fields that take you directly to the relevant information for that device. NOTE: If a device is shown as not connected, this indicates that the iSCSI Initiator on the host has not logged on. For more information, see “Targets tab” on page 49. D2D Backup System 65

1. Click on Select to view the details for the required device and then click on Edit. 2. Amend details as appropriate and click Update to apply them. See “Device parameters” on page 67 To create a new device 1. To create a new device, select the appropriate device type (Autoloader or Tape Drive) from the drop-down menu and click on Create to create a new device for the host. 2. Enter the appropriate details and click Create. You can find the iSCSI Initiator Name by running the iSCSI Initiator on the host and copying the Initiator Node Name from the General tab. See also “To edit device details” on page 66. 66 The Web Management Interface

Autoloader Name or Tape Drive Name: This is the name that is used to identify that device (autoloader or tape drive). You may like to enter a name that identifies the host or backup job with which it is associated. Total No of Cartridge Slots: This is where you define the number of slots that you require for your tape rotation strategy. For autoloaders you can select a number between 8 and 24 from the pull-down menu; each slot will initially be assigned a 200 GB cartridge. Tape drives only have one cartridge, which is always assigned a 200 GB cartridge. You can change the maximum size of the cartridge as long as it is blank. This means that you can only change the value immediately after the device is created and before it has been accessed by the backup application. See “Cartridges (Configuration)” on page 67. Emulation Type: This is the emulation type used by the backup software. The default of 1x8 G2 Autoloader is correct for most applications. An alternative of D2DBS Generic is available for certain applications. Consult your backup application technical support information for further details. If you have created an autoloader on an earlier version of the HP D2D Backup System, it will have an emulation type of ThinStor. This emulation type does not support mail slots and tape attach. If you want to connect a tape drive to the HP D2D Backup System, you must change the emulation type. (Once changed, you cannot revert to ThinStor.) iSCSI Initiator Name: This is the Initiator Node Name of the host that will back up to this device (autoloader or tape drive). It is provided automatically for the default autoloader that is created when you run the Installation wizard on a host for a first time. But you must enter it manually if you are creating a new device on this page. You can find the name by running the iSCSI Initiator on the host and copying the Initiator Node Name from the General tab. See “Manual driver installation” on page 51. To delete a device Click on Select to view the details for the required device and then click on Delete to delete it. You will be prompted to confirm that this is what you wish to do. WARNING! All data on the device will be deleted. Cartridges (Configuration) Use this page to view and configure cartridge settings. The number of slots configured on the Devices page for an autoloader determines the number of cartridge rows that are available to edit on this page; tape drives have only one cartridge. D2D Backup System 67

Location The Location column identifies each element of the autoloader that is available to hold a cartridge. There are three elements: • Slot n: which is one of the standard autoloader slots • Mail slot: which is a dedicated slot that is used to hold a cartridge that is ready for exporting to or importing from physical tape. Cartridges can only be moved into the mail slot by the backup application on the host machine. • Tape drive: which indicates that a physical cartridge is inserted in an attached tape drive and is ready for import. Bar Code: A bar code is an 8–digit, alphanumeric, unique identifier for a cartridge within the HP D2D Backup System. Bar codes are shared with the backup application, if requested. The backup application may also choose to assign its own internal identifier to the cartridge but, if it does so, it cannot assign this identifier to the Cartridge bar code. Bar codes are generated automatically but may be edited by the user. If you choose to edit the bar code: • It must be unique and must not start with the letters “CLN” or “DG” because these are reserved designations for cleaning and diagnostic cartridges. • It should be a minimum of 4 characters. Valid ASCII characters are A-Z, a-z, 0–9, space and hyphen. Anything less than 8 characters will be appended with space characters. Used Size: This shows the actual used capacity in MB or GB. If this is Blank, the cartridge may be removed, see below. Max Size: defaults to 200 GB. This value may be changed if the Used Size is Blank, see below. The maximum value allowed is 800 GB. Write Protected: is a check box that allows you to enable (checked) and disable (unchecked) write protection, see below. Last Written: tells you when the cartridge was last written to and is useful when identifying data for copying or exporting. Empty slots Empty slots are slots that contain no cartridges; all the fields contain dashes or hyphens. • Tape drive row: An autoloader consists of two devices; a tape drive and changer device. This location refers to the tape drive element of the autoloader. It is only populated when the backup application on the host is writing to or reading from the autoloader. • Mail slot row: This location refers to the slot that is used for importing and exporting data. It is only populated: • When the backup application on the host moves data into it for export to a tape drive attached to the HP D2D Backup System. Once the export has been run successfully from the Web Interface, the slot becomes empty again. • When the Web Interface is used to import data from a tape drive attached to the HP D2D. The backup application on the host is used to move the data back into a numbered slot and the mail slot becomes empty again. • Numbered slot row: This slot is empty after a Remove operation or after the backup application has moved data to the mail slot for export. Once a mail slot or numbered slot is empty, a Create button is available to create a new, blank cartridge. See “To create a cartridge” on page 70. To remove a cartridge If the Used Size of a cartridge is Blank, you will be able to remove it. Click on the Remove button. This button is not displayed, if the cartridge is not blank. D2D Backup System 69

Click Edit for the appropriate cartridge. Check the Write Protected check box for the cartridge. Your backup application will not be able to write any more data to it. To edit maximum size The only time you can resize cartridges is when you first create an autoloader or add slots and they are blank. Once the cartridges are made available to the backup application, it formats them ready for use and they are no longer blank, even if you have not yet written data to them. Similarly, the erase function on most backup applications does not return the cartridge to a completely blank state. The Max Size defaults to 200 GB, but if the Used Size is Blank, you can edit this value. The maximum value allowed is 800 GB. Click Edit for the appropriate slot. Select a value from the drop-down menu and click Update. NOTE: The maximum size indicates the physical disk space available for that slot; it will only be committed when data is written to it. Changing the maximum space does not affect actual disk usage or save disk space, but may be useful if you know you will be moving data to a physical tape with a smaller cartridge capacity. To create a cartridge Slots that are empty have an extra button, called Create. 70 The Web Management Interface

to its database or catalog) before it can access it. • If you use the Create button on an empty mail slot, you can use the backup application to move the blank, new cartridge to an empty cartridge slot, without having to run an inventory. This saves some processing time. NOTE: When you import a cartridge, you need an empty mail slot and an empty cartridge to which the backup application can move the imported data. Therefore, you may wish to leave a slot whose cartridge has been exported empty, rather than creating a new cartridge. Or to create a slot, edit the Total No Of Cartridge Slots on the Devices page, see “To edit device details” on page 66. Network (Configuration) This page is used to view and edit network settings. It is also used to turn Beacon Mode on and off. D2D Backup System 71

System supports DHCP and this is turned on by default. You may need to edit the details if there is a conflict in the IP address, or you move the host to a different network node. Be aware that any changes you make to the network settings could affect how you connect again to the HP D2D Backup System. For example, if you change the IP address, you must use the new address to log in from a web browser. To edit network settings 1. Click Edit to make the details editable. 2. Make the required changes and click Update. 3. You must now reconnect to the HP D2D Backup System using the new settings. • If you have changed the IP address, you must use the new address to log in from a web browser. • You will also need to edit the iSCSI Initiator on all hosts that are connected to the HP D2D Backup System, if you change the IP address. See “The iSCSI Initiator” on page 47. 72 The Web Management Interface

Network Name: This is the name of the HP D2D Backup System. You can use the network name, instead of the IP address, to log on to the Web Management Interface. DHCP: Check or uncheck the box to enable or disable this feature. If DHCP is turned off, you must manually specify all the network settings for the HP D2D Backup System. If DHCP is turned on, the majority of the network settings are obtained automatically. However, even when DHCP is on the Network Name must be specified. Other parameters, such as Domain Name and DNS Server Address, become optional. You can override the automatic settings and enter your own values, if required, but this is not usually necessary. IP Address: This is the IP address for the device. The HP D2D Backup System supports both dynamic (DHCP) and static IP addressing. The IP Address must be unique on the network. If you are using static IP addressing, you must also provide the subnet mask, default gateway and, optionally, domain name. Subnet Mask: This determines the subnet to which the IP address belongs. (Static IP addressing only.) Gateway: This is the node that connects the HP D2D Backup System to the network that is servicing the web pages. (Static IP addressing only.) Domain: This is the group of devices on the network to which the HP D2D Backup System belongs. (Static IP addressing only.) DNS Server Name 1/2/3: These are the DNS IP addresses. When using DHCP these may be obtained automatically. Ask your network administrator to advise what you should enter. Resetting network settings to factory defaults There are some conditions in which a previously configured device may fail to be discovered on a network and, therefore, may be unreachable if the network parameters are invalid for the network to which the device is attached. In this case, it may be necessary to reset the networking parameters and device name to factory defaults. To reset the network settings: 1. Ensure that there are no backup or restore jobs in progress to the device. 2. Press the Power On button on the front of the HP D2D Backup System three times in quick succession to reset it. After approximately 5 seconds, the HP D2D Backup System will begin its reboot sequence. NOTE: The HP D2D Backup System will be reset to factory networking settings and the Administrator password will be reset to Admin. No user data will be lost. 3. After the reboot, the device will be in DHCP mode and also available for discovery using the Installation wizard provided on the StorageWorks CD. Beacon mode Beacon mode flashes the LEDs on the HP D2D Backup System. It is useful if you have several HP D2D Backup Systems on your network and want to confirm which unit is being configured. • Click Turn Beacon On to activate beacon mode. • If you do not switch off Beacon Mode from the Network page, it will continue for 5 minutes. D2D Backup System 73

This page is used to set up details of the email servers that will be used to route messages about the HP D2D Backup System and to specify up to four email recipients. Messages are generated if a disk fails or reaches its threshold capacity, if the system reboots, if there are network problems or if there is a critical hardware failure. Email alerts are also generated for tape attach activities, when there is a separate tape drive connected to the HP D2D Backup System and the user is importing data from it, copying or exporting data to it, or scheduling tasks to carry out these activities. The HP StorageWorks D2D Backup System uses Simple Mail Transfer Protocol (SMTP), which is the established standard for transferring mail over the internet. Microsoft Exchange has a virtual SMTP server available which can be used to receive these emails and forward onward if necessary. Unix operating systems, such as Linux, have a Sendmail program included. Sendmail uses the SMTP protocol to receive and, if necessary, forward on e-mail messages. To configure email settings, the HP D2D Backup System must be on the same network as an SMTP server that it can use. • Click Edit to make the fields editable. Make changes, as appropriate and click Update. • Once you have created a recipient’s email address, use the Test button to make sure emails can be sent successfully. 74 The Web Management Interface

SMTP Server: This is the IP address of the email server. Username and Password: Some email servers require authentication to send email alerts. If required, enter a Username and a Password here that are valid on the SMTP server entered in the previous box. Sender’s Email Account: This is the email account to which the email will be attributed in the recipient’s inbox. The account must exist on the email server. For example, you may like to create an account called “[email protected]”. Recipient’s Email Address 1/2/3/4: This is the email address of the person who should receive the message. Up to four email addresses may be specified. You may only enter one address per line. Once you have configured an email recipient, there is a Test button that you can use to send a test email to the specified address. To configure Microsoft Exchange Server NOTE: Please refer to the Linux Configuration Guide on the CD-ROM for information abut configuring SMTP with Linux. It is important to check the SMTP server’s security configuration parameters to ensure that the Sender’s Email Account can be recognized. Security configuration parameters are found within the SMTP virtual server’s property pages. To view or modify them: 1. Open the Exchange Management console. 2. Click on Servers and then the server you wish to configure. 3. Click on Protocols and then SMTP. 4. You will see the default virtual SMTP server. Right click on this and select Properties. 5. Select the Access Control tab and then select Authentication. 6. The HP D2D Backup System may be used with one of the following settings: D2D Backup System 75

Password when you configure email alerts) • Basic Authentication, where a user name and password are required and should be provided when you configure email alerts NOTE: Integrated Windows Authentication is not supported with the HP D2D Backup System. If your SMTP Server requires this form of authentication and you have a spare network port, we recommend that you create a new virtual SMTP server, allowing connection only to the HP D2D Backup System. In this instance, you may lock the SMTP server to use only the HP D2D Backup System’s IP address and authentication may safely be set to anonymous for the dedicated SMTP server. Disk & RAID (Status) This page provides information about the RAID status, disk usage and status of the physical disks. Use it to identify disks that may be failing or disks that are approaching capacity. RAID status In normal operation, this shows green, OK. If one or more disks fail, it shows a warning icon. Disk usage This section shows you how much disk space has been used. Total Disk Usage: The green area is the amount of disk space committed. This always shows some value because it includes the default 2 GB space committed for each cartridge slot (see “Considerations when configuring cartridges and slots” on page 19). 76 The Web Management Interface

that the disks are reaching capacity. The Disk Usage icon on the Summary page will also indicate that disk space is running out and the Disk Capacity LED will flash. You cannot add physical disk space, but you may be able to create some space. Options for creating space, if the disks start to get full, include: • Review your backup jobs to see if you can reduce the size of backup or retention time. • Use the backup application job settings to overwrite or erase data. • Export a cartridge to tape, see “Using the Web Management interface to copy/export/import cartridges” on page 88. Autoloader 1/2/...: This is the amount of data backed up to each device. (This does not include the default 2 GB space committed for each cartridge slot. If no data has been backed up, the value is 0 GB). Each autoloader and tape drive is shown separately. Physical disks This section provides information about the physical disks. If you need to replace a disk, it is very important to obtain the serial number and the physical location of the failed disk from this page before you replace it. Table 7 Physical disk parameters Disk: This indicates the physical location of the disk and is useful if you need to replace a disk. It should relate to the wiring diagram on the access panel, but always double check against the serial number after removing a disk. Description: This is the product number of the disk. Serial No: This is the serial number of the disk. Always make a note of this before replacing a failed disk. FW Version: This is the firmware version of the disk. It may be useful for troubleshooting and when replacing a disk. Size: This is 750 GB for the HP D2D Backup System 130, 500 GB for the HP D2D Backup System 120 or 250 GB for the HP D2D Backup System 110. State: This indicates the state of the disk. Green indicates OK, amber indicates a warning. iSCSI (Status) This page shows the iSCSI details for all the devices that are configured on the HP D2D Backup System. It also shows any active connections. All available devices are shown in the top half of the page. Click on Select to view more detailed information on that device in the bottom half of the screen. This page is mainly for information and is useful in troubleshooting. The Edit facility is provided only for users who need to enable authentication. It displays additional fields in the iSCSI Authentication section. We do not recommend that you use authentication, but it will be necessary if you have enabled the Secret feature on the General tab in the iSCSI Initiator. Click Edit to make the fields editable. If a device is showing as not connected, this indicates that the iSCSI Initiator on the host has not logged on. Log on using the iSCSI Initiator and set the device as a Persistent Target for that host. This ensures that it will automatically log on again, if the host is rebooted. See “Microsoft iSCSI Initiator” on page 46. D2D Backup System 77

These pages allow you to manage copy, export and import activities between the HP D2D Backup System and an attached tape drive. They are described in detail in “Export, import and copy to an attached tape drive” on page 83. Shutdown (Admin) This option allows you to shut down the HP D2D Backup System cleanly. It is the only recommended way of powering off the device. If you remove the power in any other way and a host is carrying out a backup or restore, you may lose or corrupt data. Click Power Off and Yes to confirm. D2D Backup System 79

future jobs are scheduled to start whilst the system is shut down. If hosts do not automatically reconnect to the HP D2D Backup System when it restarts, you must reconnect manually from the iSCSI Initiator on each host, see “Targets tab” on page 49. Administration (Admin) This page allows you to manage the Administrator’s password and amend the date and time settings. When you first log on the Administrator user has a password of Admin. For security reasons, you may wish to change this. • Click Edit to make the fields editable. • Make the required changes and click Update to apply the changes (or Cancel to discard them). Resetting the password If you forget your password, you can reset the HP D2D Backup System as follows: NOTE: Resetting the password will reset the networking settings to the factory defaults and reset the Administrator password to Admin. No user data will be lost. 1. Make sure nobody is using the HP D2D Backup System before you attempt the reset. 2. Press the Power button on the front of the HP D2D Backup System three times in quick succession. Approximately 5 seconds later the HP D2D Backup System will reboot. 3. Use the device discovery tool on the HP StorageWorks CD-ROM to re-configure the network settings of the HP D2D Backup System. 80 The Web Management Interface

Make sure that there are no backup or restore jobs in progress and that no future jobs are scheduled to start whilst the firmware is upgrading. Click Yes. 4. Click Browse... and locate the upload file that you have just downloaded. 5. Click Upload to upgrade the firmware. A progress meter is displayed while the upgrade takes place. The system will reboot once it has been updated. Configuration information and data are unaffected by this process. D2D Backup System 81

complete. Do not attempt to cancel the upgrade process, or power off the machine. NOTE: The tape drive is reported to your backup application (and Windows Device Manager) as an LTO-3 device. This is the default behavior of the tape drive and there is no need and no way to change it on the HP D2D Backup System. In earlier versions of the HP D2D Backup System firmware, the tape drive was reported as an LTO-2 device. Once you upgrade to the latest version of the firmware, the backup application continues to identify existing backup devices as LTO-2 and identifies new tape devices as LTO-3, but this has absolutely no impact on how the device behaves or functions. If you delete existing devices (LTO-2) and create new ones; the new ones will be LTO-3. (It is important not to confuse emulation type with cartridge size. Emulation type is totally independent from cartridge size. The HP D2D Backup System allows you to pick whatever cartridge size you like, up to 800 GB.) Support (Admin) If you have problems, HP Support will ask you to generate a support ticket to help with troubleshooting. It provides a log of everything that has happened on your system. NOTE: Please ensure that your browser security settings allow files to be transferred from the HP D2D Backup System to your host machine. 1. Use this page to Generate a support ticket. 2. At the prompt, save the file to disk. 82 The Web Management Interface

an attached tape drive If your organization’s backup strategy also requires the ability to archive backed-up data for offsite storage, there are two ways of achieving this: • Attach an HP Ultrium tape drive directly to the HP D2D Backup System and use the copy, export and import facilities in the Web Management Interface to transfer data manually or to schedule jobs. • Attach a supported tape drive to a host machine on the storage network. If your backup application supports the copying of data between devices, you can then use the backup application to move data from the HP D2D Backup System to physical tape. This option is described in “Copy using a tape drive attached to the host” on page 99. In this chapter: • “Requirements for connecting a tape drive to the HP D2D” on page 83 • “A note about terminology” on page 83 • “Archiving methods” on page 84 • “Using the Web Management interface to copy/export/import cartridges” on page 88 • “Using a tape drive connected to host” on page 99 • “Compression” on page 98 NOTE: Always refer to http://www.hp.com/go/connectto find out which tape drive models are supported. Requirements for connecting a tape drive to the HP D2D To use this facility you need: • A tape drive, such as an HP StorageWorks Ultrium device. This should be a half-height tape drive, if it is to be installed internally. Both SAS and SCSI tape drives are supported. • A host bus adapter, HBA, for the tape drive connection (because there are no embedded SAS or SCSI ports). If the tape drive is pre-installed, an appropriate HBA is already installed. If not, you must purchase and install the HBA before connecting the tape drive. Please refer to www.hp.com/go/connect for a list of all supported host bus adapters and tape drives. For instructions on attaching the tape drive, please refer to “Attaching a physical tape drive” on page 29. NOTE: Physical tape drives attached to the HP D2D Backup System can only be accessed by the HP D2D Backup System, using the Tape Attach pages. They do not appear as attached network devices to the host system. A note about terminology Within this guide: • Export refers to the process that moves the cartridge from the HP D2D Backup System to the attached physical tape drive. D2D Backup System 83

Backup System. • Copy refers to the process that creates an additional copy of the cartridge on the physical tape drive. Backup applications may use similar terminology to describe the processes for transferring data to a slot where it can be exported to a backup device and for restoring it to the application’s database or catalog after loss or failure. Please refer to the white papers on http://www.hp.com/support for further clarification. Archiving methods Two methods are provided for archiving data to the directly attached tape device, these are Copy and Export. • Copy retains the data cartridge on the HP D2D Backup system and creates an exact copy onto a physical cartridge in the attached tape drive. • Export removes the data cartridge from the autoloader on the HP D2D Backup System once data has been successfully copied to the physical cartridge in the attached tape drive. Each method has advantages and disadvantages, as described in more detail below. NOTE: As a general recommendation, Copy is the easier of the two options to use because it does not remove the data from the HP D2D Backup system and can be managed completely from the Web Management Interface. Only use the Export option, if you need to free up some disk space. Export (and Import) require additional steps in the backup application. Cartridge copy The backup application on the host is used to back up data to a cartridge on the autoloader device (or to a standalone tape drive device) in the HP D2D Backup System. The Web Management Interface on the HP D2D Backup System is used to Copy the cartridge from the HP D2D Backup System to the attached tape drive, leaving the data on the HP D2D Backup System so that it is available for quick restore. 84 Export, import and copy using an attached tape drive

Copy creates two instances of the same cartridge; one stored on the HP D2D, the other on physical tape. Logically these are the same cartridge and the backup application has no awareness that there are two copies. If data from this cartridge is required for restore, the backup application will always restore the data from the HP D2D if it is available. The physical cartridge is, therefore, an additional copy that will be required only if the HP D2D is not available. When would Copy be used? Cartridge copies are likely to be appropriate when the user wishes to use the HP D2D Backup System for all foreseeable restore processes but requires an additional offsite copy for insurance or data security purposes. This may mean that weekly, monthly and yearly cartridges are copied. Weekly and monthly physical cartridges may be rotated; the cartridges on the HP D2D Backup System are overwritten after a period of time. Yearly cartridges may be kept indefinitely. Clear labeling of the cartridges in this case is essential because the backup application may overwrite the cartridge on the HP D2D Backup System and, therefore, lose any knowledge of the existence of the physical tape cartridge. When is it necessary to restore from a copied cartridge? There are three situations where it may be necessary to restore from the copied cartridge: • The cartridge stored in the autoloader device on the HP D2D is overwritten (accidentally) by the backup application. The backup application database is updated to reflect the new contents of the cartridge and all knowledge of the old data is lost. If the backup administrator becomes aware that this has happened, it is possible to import the physical cartridge back into the HP D2D system, from where its data can be "imported" back into the application database for restore, if required. In this case, because the backup application has overwritten the database entry for the cartridge, some external knowledge of what is on the copied cartridge is required in order to be able to decide whether the data on the copied cartridge is useful. • The whole HP D2D Backup System or a complete autoloader on the HP D2D is accidentally removed from the Web Management interface. The physical copy of the cartridge is the only copy now in existence. The backup application is still aware of the cartridge’s existence because it was not aware of the loss of the D2D system. The backup administrator has two options; if there is no required restore at this point, the administrator can deploy a new HP D2D system or create a new autoloader on the existing D2D and then import any copied cartridges back into the new D2D Backup System 85

put the copied cartridge into a physical tape drive attached to the host and restore directly from that. In either case, the backup application is aware of the cartridge’s existence. • Both the D2D system and the host are lost. In this case, the physical cartridge copy (as long as it was a full system backup) can be used for disaster recovery onto new or repaired server hardware using a tape device attached to the host server. Disadvantages of Copy 1. Data is left on the HP D2D Backup System; no disk space is freed by copying to physical cartridge. 2. It is possible for the backup application to overwrite the cartridge on the HP D2D Backup System and thus become unaware of the data that has been copied to the physical cartridge. Cartridge export The backup application on the host is used to back up data to a slot on the autoloader device (or to a standalone tape drive device) in the HP D2D Backup System. It is also used to move the data from the slot into the mail slot. This creates an empty slot where the data was moved. The Web interface on the HP D2D is used to Export cartridge data from the mail slot on the HP D2D Backup System to the attached tape drive. After a successful export, the data is removed from the HP D2D Backup System and the mail slot becomes empty. (If the export fails, the data remains in the mail slot.) Export removes the data and frees up disk space on the HP D2D Backup System and is useful for long term archival (for example in a yearly tape in a rotation scheme). If restore is needed, data can be imported (or moved back) into the HP D2D Backup System. CAUTION: Do not export cartridges that the backup application uses on a frequent basis as part of a rotation strategy because it will not be able to write to the empty slot. 86 Export, import and copy using an attached tape drive

Step 1 Use backup application on host to move cartridge to mail slot. Figure 37 Cartridge export Why use the Export functionality? The main reason for using Export is to create more space on the HP D2D Backup System. If space is not an issue, Copy is the recommended method for creating offsite backups, because it is controlled solely from the Web Management Interface and will not impact any tape rotation strategy. Export involves use of the backup application. It is directly analogous to moving a cartridge in a physical autoloader to a mail slot (import/export element) so that the backup administrator can take it offsite or put it into a firesafe. Only a single copy of the cartridge exists. It is on physical tape and no longer on the cartridge in the HP D2D Backup System. The backup application is fully aware that the cartridge location is now offsite, so cannot overwrite it without explicitly asking for the cartridge to be moved back into the autoloader. The main advantage of Export is that it frees up disk space on the HP D2D Backup System. However, care must be taken to ensure that future backups do not fail. For example, if a weekly backup tape is "exported", it will not be available for append or overwrite the next time it is required. Depending on the backup application configuration it may be possible to simply create a new blank cartridge in the autoloader for use the next time a weekly backup is required, however, in some configurations it will be necessary to re-import the physical copy in order for the next backup to occur successfully. When would Export be used? Cartridge exports are likely to be used when the user wishes to free up space on the HP D2D Backup System by exporting to physical tape a cartridge that is used infrequently. For example, if a rotation scheme uses twelve monthly tapes, it is safe to export a monthly tape from two months ago because it will not now be required (except for infrequent restores) for another ten months. The same applies to yearly tapes which may never be required again as they are kept forever. When would I restore from an exported cartridge? Restoring from an "exported" cartridge has a higher likelihood than from a copied cartridge, because the data no longer resides on the HP D2D Backup System. If a restore from an "exported" cartridge is required, the backup application will ask for the cartridge to be re-imported into the HP D2D before it can be used for restore. Exported cartridges may also be used for disaster recovery, as with copied cartridges. Disadvantages of Export 1. Restores may take longer if a physical cartridge is required for the restore. D2D Backup System 87

Cartridge import The Web interface on the HP D2D is used to Import cartridge data from the attached tape drive to the mail slot on the HP D2D Backup System. The backup application on the host is used to move the data from the mail slot back into one of the autoloader slots. 1 2 3 4 5 6 7 8 Autoloader HP StorageWorks D2D Backup System Mailslot 1 2 3 4 5 6 7 8 Autoloader HP StorageWorks D2D Backup System Mailslot Physical Tape Drive Cartridge Step 2 Use backup application on host to move the mail slot cartridge back to autoloader slot. Step 1 Use HP D2D Web Management Interface to import from tape drive. Figure 38 Cartridge import When you import a cartridge: • If it is less than 200 GB, the cartridge Max Size is set to 200 GB. • If it is over 200 GB, the cartridge Max Size is set to 400 GB. • If it is over 400 GB, the cartridge Max Size is set to 800 GB. • Cartridges over 800 GB are not writeable. The Used Size is always reported correctly. Tape spanning Spanning of multiple physical cartridges from a single cartridge in the HP D2D Backup System is not supported. The data from the cartridge on the HP D2D Backup System must not exceed the capacity of the physical cartridge on the attached tape drive. Data from only one cartridge on the HP D2D Backup System can be copied or exported at a time; it is not possible to select multiple slots and copy them to a single physical cartridge. Using the Web Management interface to copy/export/import cartridges The Tape Attach web pages allow you to configure attached tape drives, run jobs manually or schedule them, view status and job history. 88 Export, import and copy using an attached tape drive

A Quick Verify also reads back the data, but only ensures that it can be read. It may save some time if another tape device on the HP D2D Backup System is being accessed at the same time as the copy operation. No Verify is the fastest option. 3. The process checks that media is loaded in the attached tape drive and that it is blank. If it is not blank, you are given the option of overwriting it or canceling the job. (It is not possible to append data.) 4. To view job progress information and any error messages, select the Status navigation topic. To export to attached tape drive An export operation may be performed upon any non blank cartridge in the Mail slot in an autoloader device. The cartridge data is first copied from the HP D2D Backup System to the physical tape drive and then subsequently deleted from the HP D2D Backup System. However, if an error occurs during the process, the data is not deleted. It remains on the cartridge located in the Mail slot. CAUTION: Do not export cartridges that the backup application uses on a frequent basis as part of a rotation strategy. 1. Use the backup application on the host to move the cartridge into the mail slot. This action removes the cartridge from the numbered slot and leaves the slot empty. Backup applications have a number of terms to describe this action, such as remove or eject. Refer to the documentation supplied with your backup application for further details. 2.

Once the export completes successfully, the cartridge is removed from the mail slot. To import from attached tape drive An import operation may be performed on a physical cartridge in the attached tape drive. The cartridge is copied to the target device on the HP D2D Backup System. The operation will either automatically create a new cartridge in the mail slot of an autoloader device or replace the data on a cartridge in a standalone tape drive device. The mail slot or cartridge must be empty. NOTE: Only one copy, export or import job may be run at a time, regardless of the number of physical tape drives that are connected to the HP D2D Backup System. If a job is currently in progress, a warning message will be displayed when you try to set up the new job. You must wait for the current job to complete. 1. For importing to an autoloader, locate the Mail slot in the Cartridge list and click on the Import button next to it. (The Import button is only displayed if the Mail slot is empty - all the other fields contain hyphens.) For importing to a standalone tape drive, click on the Import button in the cartridge row. 2.

The process warns you that when importing cartridge data to a tape drive device on the HP D2D that contains a non blank cartridge, the data on the cartridge will be overwritten. You must click OK to continue. 4. To view job progress information and any error messages, select the Status navigation topic. 5. Once the import has completed successfully, the cartridge is in the mail slot. Use the backup application to move the data back into the autoloader slots. Backup applications have a number of terms to describe this action, such as insert. Refer to the documentation supplied with your backup application for further details. • If it is less than 200 GB, the cartridge Max Size is set to 200 GB. • If it is over 200 GB, the cartridge Max Size is set to 400 GB. • If it is over 400 GB, the cartridge Max Size is set to 800 GB. Cartridges over 800 GB are not writeable. • The Used Size is always reported correctly. Status (Tape Attach) This page displays the status of any current tape import/export or copy operations. If a job is in progress, it shows cartridge barcode and target tape drive details and relevant progress bars. The percentage completion is the amount of progress for all relevant activities in the operation, such as export and verify (if requested). 94 Export, import and copy using an attached tape drive

NOTE: If no operations are currently in progress, a link will be provided to the Tape Attach Job History page. To cancel a job To cancel a job in progress, click Cancel . You are asked to confirm that you wish to cancel the job. If a job is canceled during the copy, export or import phase, this cancels the transfer of data. • For export and copy jobs, the data remains in the mail slot or slot on the HP D2D Backup System and the physical tape on the tape drive is rewound and erased. • For import jobs, the data remains on the attached tape drive. If a job is canceled during the verify phase, the data has already been moved and it is only the verify process that is canceled. If an error occurs Errors may occur if there is a tape read/write media problem, if there is not enough capacity on the physical cartridge or if there is a verify error. Errors may also occur if the backup application accesses the cartridge that is being exported/imported or copied. Errors are reported as a dialog box on this page, which requires you to click OK to clear it. If an error occurs during export or copy, you do not lose any data. The original data remains unaltered in its original location on the HP D2D Backup System. Schedule (Tape Attach) This page allows you to create, edit and delete schedules for export and copy operations. D2D Backup System 95

• Up to 12 schedules may be created. When an export or copy scheduled job is run, it automatically overwrites the cartridge in the tape drive. If the cartridge is not blank, there is no warning and no record in the job log. NOTE: The backup application is not automatically updated with any schedules created on the HP D2D Backup System. The two are independent of each other. If you want the backup application schedules to work in conjunction with a schedule on the HP D2D Backup System, you must co-ordinate them manually. To create a schedule 1. Select Schedule from the Tape Attach section of the navigation side bar. 2. A scrollable list of existing schedules is displayed together with details of the next scheduled tape job. 3. From the pull-down lists below this list, select: • The HP D2D Backup System device (autoloader or tape drive) that contains the data for which you want to create a scheduled job. • The frequency of the job: daily, weekly, monthly by day or monthly by week . 4. Click Create. Appropriate scheduling parameters for the backup device and job frequency are displayed below. NOTE: The Create button is not present if you have already created 12 schedules. You must edit or delete existing schedules if you want to create new ones. 96 Export, import and copy using an attached tape drive

tape drives do apply hardware compression. Therefore, 200 GB of data on the HP D2D Backup System will require less space on a physical 200 GB tape cartridge. If moving data to a physical cartridge for offsite storage, there is no need for concern if the data seems to utilize less space. The capacity quoted for physical media assumes that the tape drive will be able to compress your data and reduce the file sizes by 50%, but this can be achieved only if your data is not already compressed. For example, JPEG pictures, movies, music or ZIP files, are already in compressed formats: spreadsheets, text files, high-resolution graphics are not. Most users have a mixture of compressed and uncompressed data and seldom achieve 50% compression. Some users may choose to enable software compression from their backup application to increase the storage space available to the backup application, but this can make backup jobs slower to run. However, once software compression has been applied, the data is not further compressed when it is exported to a physical tape directly attached to the HP D2D Backup System. This ensures that the user knows exactly how much physical cartridge space is required for export or copy. 98 Export, import and copy using an attached tape drive

attached to the host In this chapter: • “Requirements” on page 99 • “Using a tape drive connected to host” on page 99 • “Compression” on page 100 Requirements If you wish to copy data from the HP D2D Backup System to a tape drive connected to the host machine, you need: • A separate tape device, such as an HP StorageWorks Ultrium 460 or 448 tape drive, that can be connected directly to your host. • A backup application, running on the host, that allows you to copy data from the cartridge on your HP D2D Backup System to the physical cartridge. NOTE: It is not possible to export and import data using this method. Export and import are only supported on tape drives that are connected directly to the HP D2D Backup System. See “Export, import and copy to an attached tape drive” on page 83 Tape drives supported The HP StorageWorks Ultrium 448 or 460 tape drive is the ideal device for all copying processes because the physical cartridge size matches the maximum configured cartridge size on the HP D2D Backup System. However, by spanning across several tapes, you can also use a tape drive with a lower capacity, such as an HP StorageWorks DAT 72 tape drive. If your backup application will not allow you to span tapes, you may want to use the Web Management Interface to reduce the maximum configured cartridge size on the HP D2D Backup System. However, you must do this when you first create the autoloader or additional slots and before you have used the autoloader in any way with your backup application. See “To edit maximum size” on page 70. NOTE: Always refer to http://www.hp.com/go/connectto find out which tape drive models are recommended. Archive from host to tape process This process is controlled by the backup application. For example, HP StorageWorks Data Protector Express calls it a Copy job. D2D Backup System 99

Compression The HP D2D Backup System does not apply hardware compression to backed-up data; HP StorageWorks tape drives do apply hardware compression.
