The DFSMSdss patch byte PBNOINIT at offset X'4D' in ADRPATCH contains a non-zero value which indicates that DFSMSdss should bypass initializing the DUMP source volume following a successful DUMP operation with FCWITHDRAW specified. As a result, the physical space on the space efficient volume remains allocated.
DFSMSdss processing continues. The return code is 0.
None.
To release the allocated physical space on the space efficient volume that is the target of a FlashCopy® relationship, initialize the volume with ICKDSF. When ICKDSF initializes a space efficient FlashCopy target volume, the relationship will be withdrawn and the physical space will be released.
If bypassing the volume initialization during DUMP FCWITHDRAW operations is not desired, reset the patch byte to X'00'. See z/OS DFSMSdss Storage Administration for information on how you can set or change the patch byte value.
