CHAPTER 1: INTRODUCTION - 1 USER MANUAL Chapter 1: Introduction The WD Array Management Setup (AMS) is a utility application designed specifically for monitoring and managing the WD SATA RAID Controller. AMS runs over a local area network and makes possible RAID monitoring and management from any computer on the network and even over Internet. This allows your IT manager to watch your RAIDs and take care of them over the network. AMS Components There are three components to AMS. Depending on your installation, all three may be on the same workstation or work separately across your network: Monitoring Utility—The Monitoring Utility is a Graphic User Interface (GUI) that reports on the condition of the RAID array. It receives and displays reports on RAID condition and operation through the Message Server. The Monitoring Utility works on any PC with a TCP/IP network connection to your RAID. When installed on the computer that operates the RAID, the Monitoring Utility also provides a complete set of RAID management tools. Message Server—The Message Server normally runs on a network file server but can also run on the PC controlling the RAID. Message Agent—The Message Agent runs on the PC that controls the RAID, called the "RAID PC". The Message Agent directly monitors the RAID and sends messages through the Message Server to all PCs running the Monitoring Utility. How They Work Together The WD Array Management Setup (AMS) utility provides and easy way to set up, monitor, modify, and repair your RAID. AMS works with the WD SATA RAID Controller. AMS watches the RAID and when significant events happen, or it discovers a problem, the Message Agent sends a warning to the Message Server. The Message Server passes the warning along to all PCs running the Monitoring Utility. Warnings appear on the PC in the form of email messages and popup alerts. You can select either one or both. You can also select which events and problems AMS will report. A major benefit of AMS is that it runs over a TCP/IP network. This enables remote monitoring of your RAIDs, including offsite monitoring over an Internet connection. Once you become aware of a problem, go to the PC that controls the RAID, called the "RAID PC" to take corrective action. If you have more than one RAID PC on your network, AMS will indicate which one has the problem. AMS allows monitoring access only through the network. Management access occurs only at the RAID PC.

CHAPTER 1: INTRODUCTION - 2 USER MANUAL AMS Installation Options 1. Following are some examples of ways you can incorporate AMS into your network and RAID systems. Figure 1. LAN and Internet Connections Router & Firewall Laptop computer + Monitoring Utility A networked PC + Monitoring Utility Company LAN Internet Home-based PC + Monitoring Utility Modem Network File Server + Message Server PC + WD SATA RAID Controller + Internal RAID array + Message Agent PC + WD SATA RAID Controller + Message Agent PC + WD SATA RAID Controller + Message Agent

CHAPTER 1: INTRODUCTION - 3 USER MANUAL In the following example, there are three PCs with WD SATA RAID Controllers connected to the company's LAN. The AMS Message Agent runs on each of the PCs with a WD SATA RAID Controller. The AMS Message Server runs on the company's file server. The AMS Monitoring Utility runs on networked PCs and also on remote PCs connecting to the company network through the Internet. With this arrangement, you can monitor RAID condition and activity from offsite, such as a hotel room or home office. Figure 2. Company LAN without a File Server In the above example, there are three PCs with WD SATA RAID Controllers connected to the company's LAN, the same as before. But this network has no file server, so the AMS Message Server runs on one of the networked PCs. AMS Monitoring Utility runs on both networked PCs. If this LAN were upgraded with a suitable router and an Internet connection, you could set up offsite monitoring as in Figure 1. Figure 3. PCs with Internal RAID WD's SATA RAID Controller is designed to setup and control a RAID within the PC's enclosure. They have the same need of monitoring and management as an external RAID subsystem. All three AMS components run on the PC itself.

CHAPTER 2: INSTALLATION - 4 USER MANUAL Chapter 2: Installation To install WD Array Management Setup (AMS) is an uncomplicated procedure, once you understand your systems and how you want to use AMS. The purpose of this Chapter is to help you plan and carry out your installation of AMS. By way of review, AMS consists of three components: ! Monitoring Utility ! Message Server ! Message Agent These were described in the previous chapter. Before proceeding with the installation, you must know which component goes where. If you plan to run AMS over a network, you must know the IP addresses of each computer on the network that will be involved in your RAID monitoring and management activity. Installation Locations In the table below are possible locations for each of the three AMS components. Table 1. Acceptable AMS Component Installation Locations Monitoring Utility The Monitoring Utility installs on any computer you will use to monitor and manage the RAIDs. If your RAID runs without a network connection, install it on the RAID PC with the rest of the AMS components. If your RAIDs are networked, you can install the Monitoring Utility on any computer connected to the network. If your company has networked RAIDs and Internet access, you may choose to install the Monitoring Utility on a laptop or home-based PC for dial-in remote access. Monitoring Utility Message Server Message Agent Internet-connected PC • Network PC • • Network File Server • • RAID PC • • •

CHAPTER 2: INSTALLATION - 5 USER MANUAL Limit your installation to the computers of RAID users and your IT administrator. AMS features password protection to further limit access and provide security of your data. Figure 4. Networked RAID has many installation options Message Server The Message Server is required if your RAID PC connects to a network. If you want run AMS over a network, install the Message Server on one of your networked computers including a file server, a networked PC or the RAID PC. Only one installation of the Message Server is required for AMS to work over a network. You may install Message Server on more than one network PC or file server, but AMS's network configuration will only use one of them, thus any additional installations are useless. Do not install the Message Server on any PC that may be disconnected from the network, such as a laptop or a computer that connects via the Internet. Not only will a disconnect cause AMS to fail, but reconnecting again may involve time-consuming network configuration. Network configuration is discussed later in this chapter. Message Agent The Message Agent installs on the RAID PC, whether your RAID is networked or not. For AMS to monitor and manage a RAID, it must have Message Agent installed. If you have more than one AMS-compatible RAID PC on your network, you may install a copy of Message Agent on all of them.

CHAPTER 2: INSTALLATION - 6 USER MANUAL Operating System Support AMS is a utility designed to run on top of previously installed WD SATA RAID Controller. Generally, if your PC runs the WD SATA RAID Controller properly, it will run AMS also. Windows 2003 Server, XP, or 2000 operating systems are required to take full advantage of all the features of AMS. In some cases, you can run AMS on other Windows operating systems. This becomes an issue when running AMS over a network where there are PCs with different operating systems. Network Requirements If you plan to install AMS on a network be sure all the hosts and servers are connected and running. That is, each of the PCs, RAIDs and Servers must have a working network connection before you install AMS. For AMS to be configured over a network, you must know the IP (network) address of the RAID PC(s) in your system. The Message Server uses IP addresses to communicate with the Message Agent on the RAID PCs and the Monitoring Utility on the network PCs. See Appendix C: Networking Issues for help in finding the IP Address of the RAID PC. Installation Procedure Before you start... If you are installing AMS to run over a network, determine the computers and servers onto which you will install AMS. Obtain the IP addresses of all RAID PCs where AMS will be installed. AMS Installation With that information ready, follow these steps to install AMS on each computer or server: 1. Boot the PC/server and launch Windows. 2. If the computer is already running, exit all programs. 3. Insert the WD RAID setup and management CD into your CD-ROM drive. 4. Open the CD and locate the AMS folder. 5.

CHAPTER 5: RAID MONITORING AND MAINTENANCE WITH AMS - 43 USER MANUAL Controller Options The Controller has system information and settings several important features. Click on the Controller icon in Tree View to see the Options in Information View. To return to the previous settings, click Reset. To Apply the changes you have made, click Submit. System Information This describes the Controller type, in this case a WD SATA RAID Controller and the driver. This information may be helpful when upgrading your WD SATA RAID Controller or troubleshooting the PC. Disk Parameters Check the respective boxes to enable these features: SMART Check - SMART, an acronym for Self-Monitoring Analysis and Reporting Technology, is a feature of the disk drive software. It monitors the internal performance of the drive and reports to the PC when it finds a potential failure. SMART warns you of a developing drive failure so you can replace the drive before it actually fails. Disable Hard Disk Write Cache - Disables the Write Cache on the hard disk drives. This action will reduce performance unless you enable the Driver (WD SATA RAID Controller) Write Cache. Enable Driver Write Cache - Speeds hard disk performance by writing data to the cache on the WD SATA RAID Controller. When you are done setting controller options, click on the Array View icon and choose between Write Back and Write Though cache settings (see below).

CHAPTER 5: RAID MONITORING AND MAINTENANCE WITH AMS - 44 USER MANUAL Rebuild Setting Check the respective boxes to enable these features: Disable Hot Spare/Auto Rebuild - Disables automatic rebuilding using a hot spare drive or a newly installed replacement drive. With this option checked, you must initiate rebuilding manually. See RAID 1 (Mirroring) and Hot Spare Drive. Rebuild/Sync Rate - Allocates system resources between rebuilding the array and responding to read/write commands from the computer system. A High setting assigns most of the system resources to a rebuild or synchronization of the array. The process will finished sooner but read/write requests are handled slower. A Low setting assigns most of the system resources to handling read/write requests. Read/ write requests are handled at nearly normal speed while the rebuild or synchronization takes longer. See Rebuild an Array for more information on the rebuilding process. Array Cache Settings Click on the Array View icon and look in the Information View to see the Array Cache Setting. Enable Driver Write Cache must be checked in Disk Parameters (see above) for this option to work. Click on the dropdown menu to select the Cache Setting. Write Through - Data is written to the cache and hard drive at the same time. This arrangement is safer. Write Back - Data is written to the cache first and to the hard drive later. This arrangement increases performance at the risk of data loss if the power fails.

CHAPTER 5: RAID MONITORING AND MAINTENANCE WITH AMS - 45 USER MANUAL View Event Log The Controller's Memory Buffer records all the events that happen on the RAID, classified as Errors, Warnings, and Information. These are very useful for diagnosing and solving problems on your system. To see the Event Log, right-click on the Controller icon in Tree View and select Read Events from the popup menu. In the Event Viewer, you can view the events, make a permanent record by saving them to a file, and clear the events from the Viewer. You can also clear the events using the popup menu in Tree View. Note that the collecting and reporting of these Events is independent from the Alert Notification preferences set for the RAID System.

CHAPTER 5: RAID MONITORING AND MAINTENANCE WITH AMS - 46 USER MANUAL Arrays Create an Array The available RAID selection depends on the number of disk drives available. The table below lists the RAID Levels available with WD SATA Controller and the number of drives required. See Appendix A: RAID Concepts for a more detailed description. Table 4. RAID Levels available on the WD SATA RAID Controller. 1. In Tree View, click the + to the left of the Controller icon to see the Disk View icon. Look under the Disk View icon to see the unassigned disk drives. Unassigned drives have this icon. 2. Right-click on the Array View icon and select New Array from the popup menu. A Create Array icon appears. 3. Select the Create Array icon and go to the Create Array Settings in Information View. Figure 20. Array Creation Setting Box 4. In the Array Creation Settings box: - Type in a name for your array - Select the RAID Mode (Level) from the dropdown menu - Set the Stripe Block Size (see below) - Highlight the disk drives to add to the array - Check to enable Gigabyte Boundary, as desired (see below) Stripe Block Size (RAID 0) - This setting allows you to manually select the stripe block size. The size selected affects how the WD SATA RAID Controller sends and receives data blocks to and from the drives. In general, a larger block size is better when handling large RAID Level Name Minimum drives Maximum drives 0 Striping 1 4 1 Mirroring 2 2

CHAPTER 5: RAID MONITORING AND MAINTENANCE WITH AMS - 47 USER MANUAL data transfers (such as A/V editing and graphics) while a smaller size is better when handling email and other common server data. The default is 64 KB. When in doubt, use the default value. Gigabyte Boundary (RAID 1) - This setting rounds the size of the array down to the nearest whole gigabyte. It allows you to install a slightly smaller (within 1 GB) replacement drive, should the need arise. To enable Gigabyte Boundary, check the box. 5. Click the Create button when you are done. The new array appears in Tree View. 6. Restart your computer. The next step is to partition and format the new array using the RAID PC's Operating System. See Appendix B: Partition and Format for more information. Hot Spare Drive Using a Hot Spare Drive is an option for RAID 1 (Mirroring) arrays. To function, a Hot Spare Drive has two requirements: ! Attach a third disk drive to the WD SATA Controller without assigning it to an array ! Do not Disable Hot Spare/Auto Rebuild in the Controller Options Install a Third Drive If necessary, see the WD SATA Controller User Manual for instructions how to install disk drives with the WD SATA Controller.

CHAPTER 5: RAID MONITORING AND MAINTENANCE WITH AMS - 48 USER MANUAL Controller Settings 1. Click on the Controller icon in Tree View to see the Rebuild Setting in Information View. 2. Be sure the checkbox is NOT checked: Disable Hot Spare/Auto Rebuild - Disables automatic an automatic rebuild using a spare drive not assigned to the array. The Rebuild/Sync Rate is irrelevant to the Hot Spare Drive feature. 3. Click Submit. Array Functional When your array is first created, it will display Functional status. If you have enabled Scheduled Synchronization, you will occasionally notice that your array is Synchronizing. Then it returns again to Functional. If your array encounters a problem with a disk drive, it will display Critical status. This indicates that your array requires your attention to return to Functional. When a disk drive fails on a non-fault-tolerant (RAID 0) array, the result is an Offline status.

CHAPTER 5: RAID MONITORING AND MAINTENANCE WITH AMS - 49 USER MANUAL Array Critical When a disk drive fails on a fault-tolerant array (RAID 1) for any reason, the Array goes Critical. The array can still read and write data but fault tolerance has been lost. An Array Critical icon displays in Tree View and the alarm (if enabled) beeps quickly to call your attention to the condition. Your first action is to identify which disk drive has failed. 1. Click on the Controller icon to expand it. 2. Click on the Array Critical icon to expand it. 3. Observe and compare the disk drives currently displayed with those originally assigned to the Array. In the example above, there are two disk drives attached to the WD SATA RAID Controller and both are assigned to a RAID 1 array. The disk drive on Channel 2 does not appear. This is the failed drive. ! If you have a Hot Spare drive installed and enabled, the array will begin to Rebuild automatically. ! If you do not have a Hot Spare drive, you must replace the failed drive before a Rebuild of the array can begin. Refer to the WD SATA Controller User Manual for more information about replacing a failed drive. After you replace the failed drive, go on to “Rebuild an Array” on page 51.

CHAPTER 5: RAID MONITORING AND MAINTENANCE WITH AMS - 50 USER MANUAL Array Offline When a disk drive fails on a non-fault-tolerant array (RAID 0) for any reason, the Array goes Offline. The array cannot read or write data. All of the data on the array will be lost unless the failed drive is restored to operation. A fault-tolerant array (RAID 1) will go Offline if two disk drives fail. An Array Offline icon displays in Tree View and the alarm (if enabled) beeps quickly to call your attention to the condition. Your first action is to identify which disk drive has failed. 1. Click on the Disk View icon to expand it. 2. Click on the Array View icon to expand it. 3. Look for the drive that was part of this Array but is now missing. Observe and compare the disk drives under the Controller with those under the Array. In the example above, two disk drives attached to the WD SATA RAID Controller were assigned to a RAID 0 array. The disk drive on Channel 1 is present, but the second drive is not. The second is the failed drive. 4. When you have identified the failed drive, check its connections and run the drive manufacturer's diagnostic program in an effort to restore the drive to operation. There is no Rebuild function for a non-fault-tolerant array.

CHAPTER 5: RAID MONITORING AND MAINTENANCE WITH AMS - 51 USER MANUAL Rebuild an Array To rebuild is to restore redundancy to a RAID 1 after one of its drives has failed. Unlike Synchronization, a rebuild is a repair operation. When a drive fails for any reason, the Array goes Critical. An Array Critical icon displays in Tree View and the RAID alarm beeps quickly to call your attention to the condition. Automatic rebuild Normally, the rebuild process begins automatically when you replace the faulty disk drive. The array recognizes the new or spare drive and begins the process a few moments later. If your array has a Hot Spare drive, the rebuild begins without waiting for a replacement drive. Be sure to replace the faulty drive as soon as possible. During the rebuild process, the array is still available to read and write data but it may run noticeably slower. To enable a Hot Spare drive, change the rebuild settings and shut off the beeper, see rebuild Settings, below. If the popup messages are enabled, one will notify you when the rebuild is successfully completed. The array will return to Functional status.

CHAPTER 5: RAID MONITORING AND MAINTENANCE WITH AMS - 52 USER MANUAL Manual Rebuild After you replace a failed disk drive, the replacement drive must be rebuilt to restore the array. To initiate an array Rebuild manually: 1. In Tree View, select the Array View iconof the array you want to rebuild. 2. In Information View, click on the Start button inside the Rebuild Wizard box. 3. In the Rebuild Wizard, select the drive to be rebuilt (the replacement drive) and click Next. To confirm the rebuild choice, click Finish.

CHAPTER 5: RAID MONITORING AND MAINTENANCE WITH AMS - 53 USER MANUAL Tree View and Information View display the progress (below). During the Rebuild process, the array will be available for use but it may run noticeably slower. If the beeper is enabled, it will beep slowly during this process. If the popup messages are enabled, one will notify you when the Rebuild is successfully completed. The array will return to Functional status. Rebuild Settings Beeper - Right-click on the Controller icon and select Beeper from the popup menu. A checkmark means the beeper is enabled. Disable Hot Spare/Auto Rebuild - Disables automatic rebuilding using a hot spare drive or a newly installed replacement drive. With this option checked, you must initiate rebuilding manually. See RAID 1 (Mirroring) and Hot Spare Drive. Rebuild/Sync Rate - Allocates system resources between rebuilding the array and responding to read/write commands from the computer system. A High setting assigns most of the system resources to a rebuild or synchronization of the array. The process will finished sooner but read/write requests are handled slower. A Low setting assigns most of the system resources to handling read/write requests. Read/ write requests are handled at nearly normal speed while the rebuild or synchronization takes longer.

CHAPTER 5: RAID MONITORING AND MAINTENANCE WITH AMS - 54 USER MANUAL Synchronize an Array WD uses the term synchronization to mean an automated process of checking and correcting data and parity. Unlike a Rebuild, Synchronization is a maintenance operation. Synchronization applies to RAID 1. It takes place when an array is first created and then, optionally, on a regularly scheduled basis to maintain content integrity. Scheduled Synchronization Schedule a time for synchronization when the RAID is least busy reading and writing data. The early morning hours are often a convenient time. To enable scheduled synchronization: 1. In Tree View, select the RAID Machine icon. In Information View, scroll down to the bottom. 2. Check the Enabled box. 3. Click on the radio button beside the time interval (by day, week or month) you want. 4. Based on the time interval you selected, enter the clock time, day of the week or day of the month for the synchronization process to begin. 5. When you are done, click the Change button. The Synchronization Schedule is set. If the Schedule is disabled, it will remember its current settings.

CHAPTER 5: RAID MONITORING AND MAINTENANCE WITH AMS - 55 USER MANUAL On Demand Synchronization In addition to schedule Synchronization, you can direct the WD SATA RAID Controller to begin the Synchronization process immediately. To access this feature: 1. Right-click on the Array View icon and select Synchronize from the popup menu. 2. Click OK to the confirmation message. Information View displays the progress (below). During the Synchronization, the array will be available for use but it may run noticeably slower. If the popup messages are enabled, one will notify you when the Synchronization is successfully completed. The array will return to Functional status. Stop, Pause, Continue WD recommends that you let your rebuild run to completion. If you need to pause the process: 1. Right-click on the Array View icon of the Array that is rebuilding and select Pause from the popup menu. 2. To continue, right-click on the same icon again and select Continue from the popup menu. Delete an Array To delete an array: 1. Right-click on the Array View icon of the Array you want to delete. 2. Select Delete from the popup menu. 3. Click OK in the confirmation dialog box.

APPENDIX A: RAID CONCEPTS - 56 USER MANUAL Appendix A: RAID Concepts RAID RAID is an acronym that stands for Redundant Array of Independent Disks. It is divided into different numbered Levels. The numbers of these Levels do not mean that one Level is higher or better than another. Each Level has its own advantages and shortcomings. AMS allows you to select the RAID Level when you create an Array. The available RAID Level selection depends on which WD product you have and the number of disk drives available. The table below lists the RAID Levels obtainable with the WD SATA RAID Controller. Table 4. RAID Levels available on the WD SATA RAID Controller Following is a discussion how these RAID Levels work. RAID 0 RAID 0 is a method of striping or writing data over two or more hard disks at the same time. Multiple disks can read and write data faster than one. However, there is no data redundancy with this arrangement, so if one disk fails, all your data is lost.. RAID Level Name Minimum drives Maximum drives 0 Striping 1 4 1 Mirroring 2 2 1 3 5 7 2 4 6 8 Disk Drives Data Stripe

APPENDIX A: RAID CONCEPTS - 57 USER MANUAL RAID 1 RAID 1 takes the data written on one disk and copies it to another, making a mirror or exact copy. This arrangement does not have a significant performance advantage. If one disk fails, there is no data loss. There is no rebuild, just a copy of the data to the disk. 1 2 3 4 1 2 3 4 Disk Drives Data Mirror

APPENDIX B: PARTITION AND FORMAT - 58 USER MANUAL Appendix B: Partition and Format For Windows to recognize and work with your array, you must partition and format the array. These actions create a file structure within your array with which Windows can work. Note: If you plan to boot your computer from this array, go to Windows and Device Driver Installation under the Installation section for instructions. The instructions here are for data arrays only. Figure 40. Right-click on the My Computer icon 1. From the desktop, right-click on the My Computer icon and select Manage from the popup menu. The Computer Management window opens. 2. From the left menu, click on Disk Management. The Disk Management window opens with your new array identified as Disk 1. The Initialize Wizard appears automatically. Figure 41.

APPENDIX B: PARTITION AND FORMAT - 61 USER MANUAL When formatting is complete, your array will appear as a hard drive in the Disk Management window (above) and the My Computer window (below). Figure 45. The newly formatted array under My Computer

APPENDIX C: NETWORKING ISSUES - 62 USER MANUAL Appendix C: Networking Issues IP Address To configure AMS over a network, you must know the IP (network) address of every component. The Message Server uses IP addresses to communicate with the Message Agent on the RAID PCs and the Monitoring Utility on the network PCs. To find the IP network address: 1. Go to Start > Programs > Accessories > Command Prompt. 2. Type ipconfig/all and press Enter. The Windows IP Configuration displays (below). Figure 46. Use the Command Prompt to find your PC's IP address In the example above, the IP address of this PC is 192.168.1.132. Locate and record the IP addresses of all PCs and Servers on your network that will work with AMS. This document will help you recall individual PCs when it is time to specify their connections.

APPENDIX C: NETWORKING ISSUES - 63 USER MANUAL DHCP Issues Referring to the Figure 84 above, note that it says: Dhcp enabled. . . . . . . . : Yes This means that a DHCP server gave this IP address to this PC when the PC connected to the network. DHCP stands for Dynamic Host Configuration Protocol and refers to software that allows a file server to assign IP addresses to computers on the network. DHCP is very helpful in reducing the number of IP address a company or organization requires. The DHCP server assigns an IP address to a computer as it logs onto the network. The IP address will remain the same until the computer logs off or disconnects for any reason, such as a power failure. When the computer logs on again, it will receive a different IP address. Because IP addresses are subject to change when a DHCP server is involved, make it a point to maintain the RAID PC network connections at all times. When a disconnection happens for any reason, you must find the new IP address and enter it into the Message Server. Instructions for doing this appear under Message Server IP Address Change in Chapter 5. To avoid having to make Message Server IP Address changes, assign the RAID PC a permanent IP address. See your IT Manager for guidance.
