Mainframe Enablers TimeFinder SnapVX and zDP 8.5 Product Guide

When FREE is set to YES, the tracks that are associated with the target devices are freed from the storage resource pool. The default value is NO.

If a replication session exists on a target device, FREE processing fails. If any device in the request has a replication session, no backend space is freed.

The most likely cause of a FREE failure would be a Thin Reclaim (TRU) SDDF session. The ResourcePak Base for z/OS Product Guide describes TRU and the commands that are required to display TRU status and stop or start TRU. If multiple SCF tasks are active, each task should be checked.

FREE processing is initiated after UNLINK. If FREE processing fails, you can resubmit the same UNLINK command with FREE(YES) after the replication sessions on all target devices are removed. The “unlinked” state is recognized and only FREE processing is performed.

The FREE parameter can be specified on the UNLINK TGT command.
