About releasing pages in a THP V-VOL
Releasing pages in a THP V-VOL frees up pool capacity. When a page in the THP V-VOL contains
zero data, the free capacity of a pool increases after the pages are released. You can perform
the operation to reclaim zero pages on each V-VOL and monitor progress. For details, see
Pool Management Status window” (page 354)
. If you stop the operation to reclaim zero pages, the
zero pages that have been reclaimed cannot be restored.
Logically, there is no difference between a page with just zero data and the area of a THP V-VOL
without a page allotted. Both are effectively identical. However, the former uses pool capacity and
the latter does not.
