On a nonindexed VTOC, DEFRAG sets the DS4DOSBT bit on and the DS4EFVLD bit off in the VTOC before it starts processing and resets them at the end. This message appears if the setting or resetting cannot be done.
DEFRAG ends. The return code is 8.
None.
On a nonindexed VTOC, if the DS4DOSBT bit is on and the DS4EFVLD bit is off, allocate a temporary data set on the volume to allow DADSM to rebuild the free space information, then scratch the temporary data set.
