All SIMs generated by the VSP One Block storage systems are logged in the storage system and reported over SNMP to the hosts. In addition, the Remote Ops maintenance tool reports all SIMs to customer support.
SIMs are classified according to severity: service, moderate, serious, or acute. The service and moderate SIMs (low severity) do not require immediate attention and are addressed during routine maintenance.
The following figure illustrates a typical 32-byte SIM. SIMs are displayed by reference code (RC) and severity. The six-digit RC, which is composed of bytes 22, 23, and 13, identifies the event (for example, pair status change) or error condition and determines the severity. The SIM type, located in byte 28, indicates which component experienced the error.
