HP XP P9500 Storage - Manual (Page 301)

Description Item
For Snapshot:
Check Warning Threshold and enter a threshold.
You cannot set this item if the result of the following calculation exceeds 95:
(used-pool-capacity/pool-capacity) * 100 (%)
Select the Depletion Threshold check box, and then enter a threshold. The
minimum threshold is the pool usage rate plus 1%. The maximum threshold is
100%. Depletion Threshold
If you change the Snapshot pool, you cannot set this item.
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 you use Thin Provisioning, Smart Tiers, or Snapshot, for the pool in which only one of the
user-defined thresholds is set, 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 text box of the assigned system
threshold is blank. In the pool for which the system threshold is enabled, if either of the thresholds
is changed, the unchanged threshold is defined as follows:
•
If you change only 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 only 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.

Confirm proposed settings, name the task, and then click Apply. The task will be added to the
execution queue.
