SIMs
XP Thin Provisioning has five SIMs (Service Information Messages) to inform users of the V-VOL and pool
status. SIM levels are all Moderate. The next table describes the SIM codes. When the events in the table
occur, XP Thin Provisioning outputs SIMs and warns users, and reports trapping to SNMP. For details
about the procedure to complete SIMs, see “ Managing Pool-Related SIMs ” on page 61.
