About SIMs
Dynamic Provisioning and Dynamic Tiering provide Service Information Messages (SIMs) to report the status of the DP-VOLs and pools. If an event associated with a pool occurs, a SIM and an SNMP trap are reported.
An example of a SIM condition is if the actual pool usage rate is 50.2%, but only 50% is displayed because the capacity amount is truncated after the decimal point. If the threshold is set to 50%, a SIM and an SNMP trap are reported, even though the pool usage rate displayed on the GUI does not indicate the threshold is exceeded.
