This chapter provides an overview of SNMP including an overview of the agent and management functions: • “SNMP Manager Overview” (page 5) • “SNMP Agent Overview” (page 6) • “SNMP Manager Functions” (page 8) Unless otherwise specified, the term storage system in this guide refers to the following disk arrays: • HP StorageWorks XP24000 Disk Array • HP StorageWorks XP20000 Disk Array The GUI illustrations in this guide were created using a Windows computer with the Internet Explorer browser. Actual windows may differ depending on the operating system and browser used. GUI contents also vary with licensed program products, storage system models, and firmware versions. SNMP Manager Overview SNMP Manager and SNMP Agent Interaction The following figure shows an SNMP environment. Figure 1 SNMP Environment SNMP is an industry-standard protocol for managing and monitoring network devices, including disk devices, routers, and hubs. SNMP uses SGMP to manage the TCP/IP gateways. The standardized configuration and database of network management information is called a MIB. A standard MIB is common to all SNMP interfaces. An extension MIB is defined by the particular managed device or protocol. An SNMP manager monitors the devices, which are referred to as managed nodes. The primary types of interaction between the SNMP manager and an SNMP agent are polling and trap. Typically, the SNMP manager polls the SNMP agents on a periodic basis, to determine whether the device is operating normally. If an abnormal event occurs, the SNMP Agent can report the condition without a request from the manager, by using a message called trap. When an SNMP Manager polls the agent, the following dialog takes place: • An SNMP manager sends a request packet to an SNMP agent, which requests data regarding the status of managed node. • The SNMP agent sends a response packet back to the SNMP manager. SNMP Manager Overview 5

period, the SNMP manager re-sends the request packet. That time period is set by the system administrator, taking into account the network traffic and operation policy. • If an SNMP agent again does not respond to the re-sent packet, the SNMP manager assumes that an error has occurred. Depending on the times set for polling and response, this can take several seconds. If an SNMP agent detects an abnormal event, it sends a trap to the SNMP manager. However, if a trap is dropped in transmission, the SNMP manager does not know that it was sent. For this reason, you should use both polling and traps to determine whether an abnormal event has occurred. Management Information Base (MIB) Each managed device has certain types of information, including the configuration information, the status information for device, and statistical, which is known collectively as a Management Information Base (MIB). Each parameter is called a managed object, and it consists of the parameter name, one or more parameter(s), and a group of operations that can be executed with the object. The MIB defines the type of information that can be obtained from a managed device, and the device settings that can be controlled from a management system. SNMP Agent Overview System Configuration The SNMP agent for the HP storage system is on the SVP, which is the computer within the storage array that manages the storage system. The storage system has an exclusive LAN for communications between a disk controller and a service processor, and a separate LAN for SNMP. The configuration of each Network Management Station is determined by the type of SNMP Manager. The following figure illustrates the SNMP environment. Figure 2 SNMP Environment Architecture The following figure shows an example of SNMP operations by using an SNMP manager. 6 Overview of SNMP

SNMP Agent Functions SNMP Traps An SNMP agent reports a storage system error to a SNMP manager using the trap report function. If an error occurs, an SNMP agent issues an SNMP trap to an SNMP manager to report a failure. Issuing an SNMP trap, an SNMP agent also reports a product number, nickname, reference code, and an identifier of the component. The following table lists the events that trigger an SNMP agent trap. Table 1 SNMP Trap Triggering Events Description Events All operations in a storage system stopped. Acute failure detected. Operation in a component where a failure occurred stopped. Serious failure detected. Partial failure. Moderate failure detected. Minor failure. Service failure detected. An SNMP agent logs the most recent 256 traps, so you can see the trap history of a particular device. SNMP Agent Operations The following table lists the types SNMP Agent operations. Table 2 SNMP Agent Operations Description Operation Obtains a specific MIB object value. GET REQUEST is the request from an SNMP manager, and GET RESPONSE is the agent's response to that request. GET Continuously finds a MIB object. GETNEXT REQUEST is the request from an SNMP manager, and GETNEXT RESPONSE is the agent's response to that request. GETNEXT Reports an event (failure) to an SNMP manager. TRAP occurs without a request from the SNMP manager. TRAP SNMP Agent Overview 7

Table 3 SNMP Agent REQUEST Operations Corrective Action Description Error N/A Normal noError(0) Verify that the requested object is correct. • There are no MIB objects that are required. (Not supported). • The GETNEXT REQUEST command that is specified for the following object identifier of the last supported MIB object is received. noSuchName(2) SET operation is not supported. SET REQUEST is received. readOnly(4) Retry the operation. Error occurred for other reasons. genErr(5) SNMP Manager Functions Component Status Information You can obtain the status information for certain storage system components from an SNMP manager. The following table lists the components for which the status can be obtained. Table 4 Available Component Status Information Component Name Area Processor Storage System BUS Cache Shared memory Power supply Battery Fan Others Hard Disk Drive Power supply Disk Unit Fan Others Drive The following table lists the storage system component status as well as the trap report function.

To set the SNMP Agent properties from XP Remote Web Console computer, select Extension SNMP on SNMP Information window. Install The Manager section allows you to add and delete SNMP manager information (see “Adding SNMP Manager IP Addresses” (page 14)). Manager Displays the IP addresses of registered SNMP managers from which the SNMP agent accepts requests. If no manager is registered, the SNMP agent accepts requests from all managers. You can register up to 32 managers. IP Address list box SNMP Information Tab 11

Description Item Enter the IP address of the manager that the SNMP Agent receives the request from. • Ipv4 and Ipv6 addresses can be specified for IP Address. However, if the OS of SVP is Windows XP and you enter Ipv6 address and select Apply, an error message is displayed and the Ipv6 address is not set. • Any IP address having all values set to zero (0) cannot be specified for Ipv4 and Ipv6. • The Ipv4 address is specified by entering four (4) numbers that are separated by periods (.) using a maximum 3 digits from zero (0) to 255 inclusive (for example, XXX.XXX.XXX.XXX where X is a number). Enter the numbers only and do not enter periods. • The Ipv6 address is specified by entering eight (8) hexadecimal numbers that are separated colons (:) using a maximum 4 digits from zero (0) to FFFF inclusive (for example, YYYY:YYYY:YYYY:YYYY:YYYY:YYYY:YYYY:YYYY where Y is a hexadecimal number). Enter the hexadecimal numbers only and do not enter the colons. The cursor can be moved between the entry field using the Tab key. IP Address text box Is selected when entering an Ipv4 address. The Ipv4 address can be entered to IP address text box when this radio box is selected. Ipv4 radio box Is selected when entering Ipv6 address. The Ipv6 address can be entered to IP address text box when this radio box is selected. Ipv6 radio box Adds new IP addresses to the IP Address list box. Set Allows you to add, delete, or change SNMP trap information. The registered IP address is the trap destination for the specified community. • Each community can have more than one defined IP address (see “Adding a Community Name” (page 16) and “Adding Community IP Addresses” (page 18)). • You can register up to 32 community names and up to 32 IP addresses per community name. • You can use up to 180 alphanumeric characters for a community name. You cannot use the following: ", \, ;, :, ,, *, ?, <, >, |, /, ^, &, %, and a space before or after the community name. Community & Trap 12 Using the SNMP GUI

SNMP Agent Reference Guide: • “Mitigating SNMP Errors” (page 41) • “Calling HP Technical Support” (page 41) Mitigating SNMP Errors Use setup.exe when you install a secondary SVP. If you do not, traps could be reported to an IP address that is not specified in SNMP settings. This could have serious consequences, including the following: • SNMP Security Function If the SNMP security function is working, and a command is executed from an IP address that is not entered, you will get a no reply return and a certification error is received for a trap. • SNMP Cold Trap Function Depending on your network environment, when the SVP is rebooted you might not receive Microsoft agent SNMP agent cold traps. ◦ ◦ The Microsoft SNMP agent might report Link up/Link down Trap when the SVP reboots. ◦ A number of Link up/Link down Traps may be reported when the OS of the SVP is Windows Vista. • Abnormal Response to SNMP Command If an error occurs in the SVP, traps might not be sent. • Problems Inputting MIB Definition Files If you cannot input two or more MIB definition files because of the specifications of the SNMP manager software, use the MIB definition files for storage system. Error reports include storage system nicknames, which can be used to identify each storage system series (for example, HP StorageWorks XP24000/XP20000 Disk Array and HP StorageWorks XP12000/XP10000 Disk Array). Calling HP Technical Support If you need to call HP technical support, make sure to provide as much information about the problem as possible. Include the circumstances surrounding the error or failure, the storage system Remote Web Console configuration information saved in the floppy diskette(s) by the FD Dump Tool, the exact content of any messages displayed on the Remote Web Console, and the severity levels and reference codes of service information messages (SIMs) displayed on the Status tab of the Remote Web Console main window.
