For a DEFRAG, protected data set relocation cannot be done because DEFRAG requires a free DSCB for processing protected data sets. For a DUMP, nnn free DSCBs are required to successfully complete a subsequent RESTORE FULL operation.
For DEFRAG, only unprotected data sets are relocated, and the final return code is 4. For DUMP, the DUMP FULL operation continues, and the final return code is 4.
None.
If temporary data sets exist on the volume, you can scratch them. If no temporary data sets or not enough space exists on the volume, you can dump one or more data sets to free a DSCB and rerun the job. If there is enough space on the volume, you can also use ICKDSF REFORMAT EXTVTOC to enlarge the VTOC and then rerun the job.
