Service Information Messages (SIMs)
The VSP G100, G200, G400, G600, G800 and VSP F400, F600, F800 storage systems generate 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 SVP and displayed in the Alert tab of the Storage Navigator Storage System window.
For more information, see the Hitachi Device Manager - Storage Navigator User Guide.
During TrueCopy operations, the primary and secondary systems 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 on the storage system, each SIM results in an SNMP trap being sent to the appropriate hosts.
For details about SNMP operations, see the SNMP Agent User Guide, or contact the Hitachi Solution Support Center.
