Yep. Release a page of virtual volume for Dynamic Provisioning, Dynamic Provisioning for Mainframe, Dynamic Tiering:

raidcom modify ldev -ldev_id [CU:ID] -status discard_zero_page

HCS CLI also has this


RunZeroPageReclaim performs a zero-page reclaim operation, which returns unused capacity in DP volumes (virtual volumes).

Command execution example:HiCommandCLI RunZeroPageReclaim -o "D:\logs\RunZeroPageReclaim.log" model=USP_V serialnum=10007 devnums=06:AC
