About releasing pages in a THP V-VOL
You can reclaim zero pages and release the appropriate pages if the status of all data in the pages
in the V-VOL reads no logical records (referred to as zero page). 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 in Remote Web Console. For details, see
“View Pool Management
Status window” (page 293) . 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.
