HP XP P9500 Storage - Manual (Page 128)

NOTE: For a pool where only one user-defined threshold is set, the system assigns the system
threshold (fixed at 80%). The lower value of the single user-defined threshold and the fixed
system threshold are set as the Warning Threshold; the higher value of the two is set as the
Depletion Threshold. After one of the thresholds is changed, the system threshold cannot be
enabled again.
A SIM code is reported when the pool usage capacity exceeds the threshold changes.

Select multiple pools using the Shift key (if the pools are adjacent), or using the Ctrl key (if the
pools are not adjacent).

Working with SIMs
About SIMs
Thin Provisioning and Smart Tiers provide Service Information Messages (SIMs) to report the status
of the THP V-VOLs and pools. The SIM level is Moderate. If an event associated with a pool occurs,
a SIM is output to Remote Web Console to alert the user, and an SNMP trap is reported to the
open-systems host.
An example of a SIM condition is if the actual pool usage rate is 50.1%, but only 50% appears
on in Remote Web Console 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 appearing in Remote Web Console does not indicate the threshold is exceeded.
