1 Introduction This topic provides an overview of the SNMP implementation for monitoring the XP7 Storage, including the agent and management functions. SNMP Manager overview SNMP Manager is installed in the network management station. It collects and manages information from SNMP agents installed in the managed devices on the network.
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 The standardized configuration and database of network management information is called a Management Information Base (MIB). A standard MIB is common to all SNMP interfaces.
SNMP Agent functions The SNMP Agent is mounted on the managed device (hard disk, etc.) in the network. It collects error information, the usage condition, and other information about the device, and forwards the information to the SNMP Manager. The SNMP Agent reports disk storage system failures to the manager using the functions described in the following paragraphs. SNMP traps An SNMP Agent uses the SNMP trap function to report a storage system error to the SNMP Manager.
Table 3 REQUEST operation errors Error Description Corrective action noError (0) Normal N/A noSuchName (2) • There are no MIB objects that are required. (Not supported.) Verify that the name of 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. SET operation is not supported. genErr (5) Error occurred for other reasons. Retry the operation.
2 Using SNMP This topic describes how to use Remote Web Console to manage SNMP Manager IP addresses, community names, and community IP addresses. It also explains how to test SNMP trap reports. Editing alert settings This topic describes how to set the Edit Alert Settings. CAUTION: Be sure to document your storage system name before this process, because the settings will be cleared when the SVP is replaced.
Changing a community IP address This topic describes the procedure to change a community IP address. Prerequisite: You must have Storage Administrator (Initial Configuration) role to perform this task. 1. From the Settings menu, select Environmental Setting - Edit Alert Settings. 2. In the Edit Alert Settings window, select the SNMP tab. 3. In the SNMP Trap Settings, select one or more specific IP addresses, and click SNMP Trap Change. 4.
For more information, see the HP XP7 Remote Web Console User Guide. Deleting a community name This topic describes how to delete a community name. Prerequisite: You must have Storage Administrator (Initial Configuration) role to perform this task. 1. From the Settings menu, select Environmental Setting - Edit Alert Settings. 2. In the Edit Alert Settings window, select the SNMP tab. 3. In the SNMP Trap Settings, click Community - Delete. 4. Click Finish. 5.
Deleting an SNMP Manager IP address This topic describes how to delete an SNMP Manager IP address. Prerequisite: You must have the Storage Administrator (the Initial Configuration) role to perform this task. 1. From the Settings menu, select Environmental Setting - Edit Alert Settings. 2. From the Edit Alert Settings window, select the SNMP tab. 3. In the SNMP IP Security window, click Extension SNMP (check box).
3 SNMP supported MIBs This topic describes the standard and extension MIB specifications, the SNMP GUI, and trap configuration. Trap configuration Failure report trap An extension trap protocol data unit (PDU) includes the product number of the device that experienced the failure, the device nickname, and a failure reference code. If you obtain the information with GetRequest command, access the MIB by using the product number of the device as an index. The following table shows the failure report trap.
Table 8 Supported MIBs MIB Standard MIB: MIB-II Extension MIB Supported? system group Yes interface group No at group No ip group No icmp group No tcp group No udp group No egp group No snmp group No Yes MIB access mode The access mode for MIB in all communities is read only. If you send a GET request for a SET operation, you will receive NoSuchName as a GET RESPONSE. An example object system supported by an SNMP Agent is shown the following figures.
Figure 6 Object system (3) MIB mounting specifications The supported MIB mounting specifications are as follows: • mgmt OBJECT IDENTIFIER ::= {iso(1) org(3) dod(6) internet(1) 2 } • mib-2 OBJECT IDENTIFIER ::= {mgmt 1} An SNMP Agent mounts only system groups in mib-2, as shown in the following. Table 9 System groups Name Description Mounted value sysObjectID {system 2} This is the product identification number. Fixed value. See “Object identifier system” (page 14). 1.3.6.1.4.1.116.3.11.4.1.

5 Troubleshooting This topic provides troubleshooting information for the SNMP Agent. Getting help If you have difficulty with any of the procedures included in this topic, or if a procedure does not provide the answer or results you expect, please contact HP Technical Support. Solving SNMP problems 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.

Glossary allocation The ratio of allocated storage capacity versus total capacity as a percentage. Allocated storage refers to those logical devices (LDEVs) that have paths assigned to them. Allocated storage capacity is the sum of the storage of these LDEVs. Total capacity is the sum of the capacity of all LDEVs on the disk array. BC P9000 or XP Business Copy. An HP application that provides volume-level, point-in-time copies in the disk array.
to be associated with 1 to 36 LDEVs. Essentially, LUSE makes it possible for applications to access a single large pool of storage. M-VOL Main volume. MCU Main control unit. OPEN-x A general term describing any of the supported OPEN emulation modes (for example, OPEN-E). There are two types of OPEN-x devices: legacy OPEN-x devices with a fixed size (such as OPEN-3, OPEN-8, OPEN-9, and OPEN-E), and OPEN-V, which has a variable size and is a CVS-based volume.
