HP XP P9500 Storage - Manual (Page 266)

CAUTION: If you want to change multiple parameters for a pool two or more times, wait until
the current task finishes, and then change the next settings. If you attempt to change settings before
the current task finishes, only the settings in the next task will be applied, so the result might be
different from what you expected.
If only one user-defined threshold is set for the pool, the system threshold (fixed at 80%) is enabled.
When the Edit Pools window opens on the pool to which the system threshold is enabled, the lower
value of the user-defined threshold or the system threshold is assigned to the Warning Threshold
and the other value is assigned to the Depletion Threshold. In this case, the system threshold text
box is blank. Additionally, if the system threshold is enabled for the pool, if either one of the two
thresholds is changed, the unchanged threshold is defined as follows:
•
If you change Warning Threshold, the higher value of the user-defined threshold or the system
threshold (fixed at 80%) is defined as Depletion Threshold.
•
If you change Depletion Threshold, the lower value of the user-defined threshold or the system
threshold (fixed at 80%) is defined as Warning Threshold.
In this case, note that the reported SIM code number changes when the pool usage capacity
exceeds the threshold. If the threshold changes once, the system threshold is not enabled again.
