Guide
Abstract
This guide describes the implementation of Simple Network Management Protocol (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. The intended audience is a storage system administrator or authorized
service provider with independent knowledge of HP StorageWorks XP storage systems and Remote Web Console.

  • Page 8: Management Information Base (Mib)

    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.

  • Page 9: Snmp Agent Functions

    Figure 2 SNMP Environment Architecture The following figure shows an example of SNMP operations by using an SNMP manager. 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.
