The storage system generates a service information message (SIM) to notify users of a possible service requirement. The SVP reports all SIMs related to TrueCopy operations.
SIMs are classified according to the following severities: service, moderate, serious, or acute.
All SIMs are recorded on the SVP or storage system and displayed in the Alert tab of the Device Manager - Storage Navigator Storage System window.
For more information, see the System Administrator 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 on the storage system, each SIM results in an SNMP trap being sent to the appropriate hosts.
For further information about SNMP operations and SIMs, see the System Administrator Guide, Hitachi Alert Notification Guide, SIM Reference Guide, or contact customer support.
