Hi John,

Yes you can delete these files which are generated from the AUTODUMP
facility of DFSMShsm and are controlled by the DUMPCLASS(VTOCCOPIES)
setting.  In the old days before DFSMS then defining a volume as Primary
to be managed by DFHSM would dictate whether the volume would have Backup,
Migration and/or Dump functionality associated.  Of course with DFSMS we
now do this at the DFSMS construct (E.g. STORGRP) level.  So it would seem
that the Level 0 (Primary) DASD volume no longer exists, but the VTOCCOPY
files do.

The DFSMShsm design of this process is extracted verbatim:

“When a volume dump of a level 0 volume is directed to a dump class that
has a VTOCCOPIES value greater than zero, a VTOC copy data set is created.
Only one VTOC copy data set is created for each dump generation. If more
dump copies of a given volume associated with the same dump class are kept
than the specified limit of VTOCCOPIES, the VTOC copies created for the
older dumps are excess. If the VTOC copy is in excess for all other dump
copies in the same generation, the VTOC copy is deleted and uncataloged
during this phase of automatic dump.”

You might also want to check if you have any legacy tape volumes from
dumps of these non-defined DASD volumes and determine whether you need
these or not.  Hopefully they will have previously cycled out naturally as
well.

Regards, UK Mikey.
