HP StorageWorks XP24000/XP20000 SNMP Agent Reference Guide Abstract This guide describes the implementation of SNMP for monitoring HP StorageWorks XP24000/XP20000 storage systems. The guide lists the monitored storage system components and supported traps, describes the trap protocol and extension MIB, and explains how to use the GUI to limit SNMP access to specific SNMP managers.

1 Overview of SNMP 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 Explore
• SNMP uses the TCP/IP UDP. If the SNMP agent does not 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.
Figure 3 Example of SNMP Operations 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.
Error Report The following table lists the errors to be reported for the REQUEST operations. Table 3 SNMP Agent REQUEST Operations Error Description Corrective Action noError(0) Normal N/A noSuchName(2) • There are no MIB objects that are required. (Not supported). Verify that the requested object is correct. • The GETNEXT REQUEST command that is specified for the following object identifier of the last supported MIB object is received. readOnly(4) SET REQUEST is received.
Table 5 Storage system Component Status Types (continued) Status Description Moderate failure detected Partial failure. Service failure detected Minor failure.
2 Using the SNMP GUI This chapter explains the SNMP information tab: • “SNMP Information Tab” (page 10) SNMP Information Tab The SNMP IP Security tab allows you to limit SNMP access to specific SNMP managers and to enter SNMP trap addresses. Click Go – Install – SNMP SNMP IP Security in the menu bar of Remote Web Console Main window. The SNMP IP Security tab displays. Select the SNMP SNMP IP Security tab (see “SNMP Information Tab” (page 11)).
Figure 4 SNMP Information Tab Table 6 SNMP Information Tab Item Description Install The Extension SNMP check box is selected if the SNMP Agent feature is enabled. To set the SNMP Agent properties from XP Remote Web Console computer, select Extension SNMP on SNMP Information window. Manager The Manager section allows you to add and delete SNMP manager information (see “Adding SNMP Manager IP Addresses” (page 14)).
Table 6 SNMP Information Tab (continued) Item Description IP Address text box 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.
Table 6 SNMP Information Tab (continued) Item Description System Group Allows you to add, delete or change SNMP system group information. If system group information has already been registered, the registered information displays. To register the system group information, the Extension SNMP check box must be selected. When you register system group information, select Apply. System group information is as follows: • Name: Connected storage system name.
3 Performing SNMP Operations This chapter covers adding and deleting an SNMP manager IP address, adding and deleting a community name, along with adding and deleting a community IP address: • “Adding SNMP Manager IP Addresses” (page 14) • “Deleting SNMP Manager IP Addresses” (page 15) • “Adding a Community Name” (page 16) • “Deleting a Community Name” (page 17) • “Changing a Community Name” (page 17) • “Adding Community IP Addresses” (page 18) • “Deleting a Community IP Address” (page 19) • “
6. Select Apply to implement the changes, or select Cancel to cancel the changes, then select OK on the confirmation message. 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. 2. 3. 4. 5. 6. Change to Modify mode. Log on to Remote Web Console. Click Go – Environmental Settings – SNMP Information in the menu bar of Remote Web Console Main window.
Figure 6 Delete IP Address Menu Adding a Community Name To add a community name: 1. 2. 3. 4. 5. 6. 7. 8. Change to Modify mode. 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 “SNMP Information Tab” (page 11)). In Community & Trap box, select and right-click Community. Add Community menu displays (see “Add Community Menu” (page 16)). Select Add Community.
Figure 8 Add Community dialog box Deleting a Community Name To delete a community name: 1. 2. 3. 4. 5. 6. Change to Modify mode. 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 “SNMP Information Tab” (page 11)). In Community & Trap, select and then right-click the unwanted community. The Delete Community menu displays (see “Delete Community Menu” (page 17)).
4. 5. 6. 7. Select Change Community. The Change Community dialog box displays (see “Change Community dialog box” (page 18)). 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 %. You can also use spaces, except at the beginning or the end of the name. Select OK.
NOTE: 5. 6. • If the values for an IP address are all set to zero (0), that address cannot be specified for Ipv4 and Ipv6. • The Add IP Address dialog box does not support shortened expression for Ipv6 address. Enter 8 hexadecimal numbers that are separated colons (:) to a maximum 4 digits from zero (0) to FFFF inclusive. • When the OS of the SVP is Windows XP, if you enter an Ipv6 address and select Apply, an error message is displayed and the Ipv6 address cannot be set. Select OK.
5. 6. 7. Select Delete IP Address. A confirmation message displays. Select OK or Cancel. The selected IP address is deleted from Community & Trap, but the change is not yet implemented. Select Apply or Cancel. Select OK on the confirmation message. Figure 14 Delete Community IP Address Menu Testing the SNMP Trap Report To test the SNMP Trap report: 1. 2. 3. 4. 20 Log on to Remote Web Console. Click Go – Environmental Settings – SNMP Information in the menu bar of Remote Web Console Main window.

6 Troubleshooting This chapter provides troubleshooting information for the HP StorageWorks XP24000/XP20000 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.
