SIM reports of GAD operations

If a storage system requires maintenance, a SIM is issued and displayed in
the Alerts window of Device Manager - Storage Navigator. A SIM is also
issued when the pair status of a primary or secondary GAD volume changes.
SIMs are categorized into service, moderate, serious, and acute according to
their severity. The GAD operation history appears in the Histories window.
If SNMP is installed on the storage systems, SIMs trigger an SNMP trap that
is sent to the corresponding server. For details about SNMP operations, see
the Hitachi Command Suite User Guide or the Hitachi SNMP Agent User
Guide.
