1 Overview of SNMP 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). A standard MIB is common to all SNMP interfaces.
Component Status Information You can obtain the status information for certain storage system components from an SNMP manager. Table 1 (page 6) lists the components for which the status can be obtained. Table 1 Available Component Status Information Area Component Name Disk Controller Processor BUS Cache Shared memory Power supply Battery Fan Others Disk Unit Power supply 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 (page 7) illustrates the SNMP environment.
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 parameters, and a group of operations that can be executed with the object.
Error Reporting Table 5 (page 9) shows errors to be reported for the REQUEST operations. Table 5 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.
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 (page 10)). NOTE: Option buttons (left side of the window) and subsystem information icons (window upper right corner) have been omitted from the screen shot.
NOTE: To set the SNMP Agent properties from HP StorageWorks 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). ◦ The IP Address list box: 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.
NOTE: The device location is required to use SNMP Agent. Make sure to document the device location, because the settings will be cleared when SVP is replaced. 12 • Apply implements settings made on this window. • Cancel cancels settings made on this window.

5 SNMP Supported MIB Trap Configuration Extension Trap Specifications The specifications of the supported extension trap are as follows. Table 6 Extension Trap Specifications Operation Specification Mounting Value SNMP Community Specified community name — Protocol Data Unit (PDU) Type Trap PDU 4 Enterprise ID Agent Identifier 1.3.6.1.4.1.116.3.11.4.1.1 Agent IP Address Agent IP Address — Generic Trap Code EnterpriseSpecific — Specific Trap Code See Table 7 (page 19).
NOTE: For example, the object identifier for a failure in a disk controller processor would be 1.3.6.1.4.1.116.5.11.4.1.1.6.1.2. Standard MIB Specifications Supported MIB Table 9 (page 20) shows the supported MIBs. If you send a GET request for an object (MIB) that is not supported, you will receive NoSuchName as a GET RESPONSE.

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.
