  • About releasing pages in a DP-VOL

    Releasing pages in a DP-VOL frees up pool capacity. When a page in the DP-VOL contains zero data, the free capacity of a pool increases after the pages are released. You can reclaim zero pages on each V-VOL and then monitor the progress on the View Pool Management Status window. If you stop the reclaim zero pages operation, the zero pages that have already been reclaimed cannot be restored.
