Why does HP XP7 Storage pool usage level exceed the threshold?
If the pool usage level exceeds the threshold in HP Storage, it could be due to too many THP V-VOLs associated with the pool, too much data stored in the pool, or the pool's capacity being insufficient, or even the threshold being too low. To resolve this, consider adding pool-VOLs to increase the pool's capacity, reclaim zero pages to release space, or set a larger value for the pool's threshold.

Contact HP technical support to restore the cache memory.
