Service Information Messages (SIMs)

The Hitachi Virtual Storage Platform G200, G400, G600 generates a service information message (SIM) to notify users of a possible service requirement for the storage system. SIMs can be generated by the system's channel and storage path microprocessors or the service processor (SVP). The SVP reports all SIMs related to TrueCopy operations.

All SIMs are recorded on the Hitachi Virtual Storage Platform G200, G400, G600 SVP and displayed in the Alert tab of the Device Manager - Storage Navigator Storage System window.

For more information, see the Hitachi Storage Navigator User Guide.

During TrueCopy operations, the primary and secondary system generate a service SIM when P-VOL or S-VOL pair status changes for any reason, including normal status transitions (for example, COPY to PAIR).

• SIMs generated by the primary system include the P-VOL device ID (byte 13).

• SIMs generated by the secondary system include the S-VOL device ID (byte 13).

If SNMP is installed and operational for the Hitachi Virtual Storage Platform G200, G400, G600, each SIM results in an SNMP trap being sent to the appropriate hosts.

For further information about SNMP operations and SIMs, see the Hitachi Command Suite User Guide, or contact Hitachi Data Systems customer support.
