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 “View
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.
