RunZeroPageReclaim
RunZeroPageReclaim performs a zero-page reclaim operation, which returns unused capacity in
THP volumes (virtual volumes).
Zero-page reclaim can be performed for THP 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.
NOTE:
This command can be used only with P9500 and XP24000/XP20000. The microcode version required
for XP24000/XP20000 is 60-07-00-XX/XX or later.

command. In the execution result, use the arrayType value or the displayArrayType value to
specify the model parameter, and use the serialNumber value to specify the serialnum parameter.
devnums: Obtain this value from the execution result of the GetStorageArray (subtarget=LDEV)
command. Execute this command by specifying only the model and serialnum parameters, and
LDEV for the subtarget parameter. In the execution result of this command, the devNum value of
an LDEV appears under An instance of LDEV. Use this devNum value to specify the devnums
parameter.
