Releasing Compatible FlashCopy relationships
This section describes an issue with the TSO FCWITHDR command in releasing a Compatible
FlashCopy relationship. There is no DFSMSdss command for releasing a Compatible FlashCopy
V2 relationship.
If the following operation is executed, the FCWITHDR command may be issued automatically by
a host server and relationships may be deleted:
•
A user deletes dataset.
•
A user initializes a volume.
•
Temporary dataset is deleted when a job completes.
You can release allocated space for a space-efficient target volume (TSE-VOL) by using the following
parameters:
•
IDCKDSF: RELATSPACE
•
ANTRQST Macro: SPACEREL
If you do not specify these parameters when releasing relations of TSE-VOLs, relations can be
deleted but the capacity of targets cannot be released.
