About this Guide The HP StorageWorks XP24000 SNMP Agent Reference Guide describes the SNMP Agent interface for the HP storage system. Please read this manual carefully to understand how to manipulate your storage systems using the Remote Web Console software, and maintain a copy that is accessible from the Remote Web Console computer for reference purposes. The term storage system in this guide refers to an HP StorageWorks XP24000 Disk Array.
• 1 TB (terabyte) = 1,0004 bytes HP XP storage systems use the following values to calculate logical storage capacity values (logical devices): • • • • • 1 1 1 1 1 KB (kilobyte) = 1,024 bytes MB (megabyte) = 1,0242 bytes GB (gigabyte) = 1,0243 bytes TB (terabyte) = 1,0244 bytes block = 512 bytes Window Illustrations The windows shown in this guide were displayed on a Windows computer with the Internet Explorer browser.
1 Overview of SNMP Network Management Station (SNMP Manager) Managed Device (SNMP Agent) Figure 1 SNMP Environment Simple Network Management Protocol (SNMP) is an industry-standard the protocol for managing and monitoring network devices, including disk devices, routers, and hubs. SNMP uses Simple Gateway Management Protocol (SGMP) to manage the TCP/IP gateways. The standardized configuration and database of network management information is called a Management Information Base (MIB).
Component Status Information You can obtain the status information for certain storage system components from an SNMP manager. Table 2 on page 10 lists the components for which the status can be obtained. Table 2 Available Component Status Information Area Component Name Processor BUS Cache Disk Controller Shared memory Power supply Battery Fan Others Power supply Disk Unit Fan Others Drive The following status is indicated for each component status as well as the trap report function.
2 About SNMP Operations System Configuration The SNMP agent for the HP storage system is on the service processor (SVP), which is the computer within the storage array that manages the disk controller (DKC). 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. Figure 2 on page 11 illustrates the SNMP environment.
SNMP Manager SNMP Agent GET REQUEST GET RESPONSE GETNEXT REQUEST GET RESPONSE TRAP Figure 3 Example of SNMP Operations 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).
Table 4 SNMP Trap Triggering Events Events Description Acute failure detected. All operations in a subsystem stopped. Serious failure detected. Operation in a component where a failure occurred stopped. Moderate failure detected. Partial failure. Service failure detected. Minor failure. An SNMP agent logs the most recent 256 traps, so you can see the trap history of a particular device. SNMP Agent Command Table 5 on page 13 shows the types SNMP Agent operations.
• SNMP uses the TCP/IP User Datagram Protocol (UDP). If the SNMP agent doesn’t respond within a specified time 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.
3 Using the SNMP GUI SNMP Information Tab The SNMP Information tab allows you to extend the number of LUs and cache memory using Just in Time Storage. Click Go – Environmental Settings – SNMP Information in the menu bar of Remote Web Console Main window. The SNMP Information tab displays. Select the SNMP Information tab (see Figure 4 on page 15). Note: Option buttons (left side of the window) and subsystem information icons (window upper right corner) have been omitted from the screen shot.
• • • • 16 • Set: Adds new IP addresses to the IP Address list box. Community & Trap 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 ad dress (sees “Adding a Community Name” on page 19 and “Adding Community IP Addresses” on page 21). • You can register up to 32 community names and up to 32 IP addresses per community name.
4 Performing SNMP Operations Adding SNMP Manager IP Addresses To add SNMP Manager IP addresses: 1. Log on to open Remote Web Console Main window. Change to Modify mode (see HP StorageWorks XP24000 Remote Web Console User’s Guide if you need instructions). 2. Click Go – Environmental Settings – SNMP Information in the menu bar of Remote Web Console Main window. The SNMP Information window is displayed (see Figure 4 on page 15). 3.
Figure 5 Adding SNMP Manager IP Address (Top: Before Setting, Bottom: After Setting) Deleting SNMP Manager IP Addresses To delete an SNMP Manager IP address: 1. Change to Modify mode. 2. Log on to Remote Web Console. Click Go – Environmental Settings – SNMP Information in the menu bar of Remote Web Console Main window. The SNMP Information window is displayed (see Figure 4 on page 15). 3. Select one or more unwanted IP addresses in IP Address list box.
Figure 6 Delete IP Address Pop-Up Menu Adding a Community Name To add a community name: 1. Change to Modify mode. 2. Log on to Remote Web Console. Click Go – Environmental Settings – SNMP Information in the menu bar of Remote Web Console Main window. The SNMP Information window is displayed (see Figure 4 on page 15). 3. In Community &Trap box, select and right-click Community. Add Community pop-up menu displays (see Figure 7 on page 19). 4. Select Add Community.
Figure 8 Add Community dialog box Deleting a Community Name To delete a community name: 1. Change to Modify mode. 2. Log on to open Remote Web Console Main window, click Go – Environmental Settings – SNMP Information in the menu bar of Remote Web Console Main window. The SNMP Information window is displayed (see Figure 4 on page 15). 3. In Community & Trap, select and then right-click the unwanted community. The Delete Community popup menu displays (see Figure 9 on page 20). 4.
3. Select and then right-click the community name that you want to change in Community & Trap. The Change Community popup menu displays (see Figure 10 on page 21). 4. Select Change Community. The Change Community dialog box displays (see Figure 11 on page 21). 5. In the Community text box, overwrite the old community name with a new community name. You can use up to 180 alphanumeric characters, except for ", \, ;, :, ,, *, ?, <, >, |, /, ^, &, and %.
5. Select OK. The new IP address displays in Community & Trap, but the change is not yet implemented. 6. Select Apply. Select OK or Cancel. Figure 12 Add IP Address Pop-Up Menu Figure 13 IP Address dialog box Deleting a Community IP Address To delete a community IP address: 1. Change to Modify mode. 2. Log on to Remote Web Console.

7 Troubleshooting 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.
