Use Device Support Facilities (ICKDSF) to convert a VTOC to a non-indexed
format to update the volume. If you do not, keep the following considerations
in mind:
- Initializing a Volume: If you do not change
the volume serial number, you must vary the volume offline before
starting the job.
- Restoring a Volume from a Dump Tape: There
are no operational requirements if you change the volume serial number
or do a partial restore that does not modify the VTOC or VTOC index.
If you do a restore, and modify the VTOC or VTOC index without changing
the volume serial number, you must vary the volume offline after it
is restored.
- Copying a Volume: There are no operational
requirements if you change the volume serial number of the receiving
volume or do a partial dump without modifying the VTOC or VTOC index.
If you modify the VTOC or VTOC index without changing the volume serial
number, you must vary the receiving volume offline after it is copied.
