RunZeroPageReclaim
RunZeroPageReclaim performs a zero-page reclaim operation, which returns unused capacity in
THP/Smart volumes (virtual volumes).
Zero-page reclaim can be performed for THP/Smart volumes that satisfy either of the following
conditions:
• The volumes do not constitute a copy pair.
• The volumes constitute a copy pair that was created by either Continuous Access Software or
Continuous Access Journal Software.
You can use the GetZeroPageReclaimStatus command to check whether a zero-page reclaim
operation has finished.
