Initializing the volume with the FCWITHDRAW keyword

During DUMP FULL and DUMP TRACKS operations, DFSMSdss invokes ICKDSF to initialize the source volume of the DUMP operation at the end of the dump processing, when all of the following conditions are true:

FCWITHDRAW is specified
The VTOC tracks on the source volume of the DUMP operation are the target of a FlashCopy® relationship
TRACKS, if specified, designates one extent range that represents the entire volume
The volume is not a VM-format volume (CP volume)
The volume supports data set FlashCopy or space efficient FlashCopy.

If these conditions are not met, DFSMSdss performs a FlashCopy withdraw operation only.

For information about how to disable the volume initialization function, refer to Changing the default initialization processing during DUMP with FCWITHDRAW (OA18929).
