The following options of Compatible FlashCopy-to-PPRC primary volume must be specified at the
same time:
• DFSMSdss: FCTOPPRCPRIMARY

Releasing Compatible FlashCopy relationships
When you use the DFSMSdss command, keep in mind that the DFSMSdss command cannot release
Compatible FlashCopy relationships.
In the following situations, the FCWITHDR command might be issued automatically by a host server,
and relationships might 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 are deleted
but the allocated capacity of targets is not released.
