Write dump VTOC copy data set

If you request it, DFSMShsm makes a dump VTOC copy data set for each dump generation that is made for a volume. When DFSMShsm makes a dump VTOC copy data set, it also catalogs the data set. Only a single dump VTOC copy is made for each generation, no matter how many copies are in the generation.

The dump VTOC copy data sets are physical sequential data sets written on ML1 volumes. They contain an entry for each data set VTOC entry that is in the source volume’s VTOC when the volume is dumped. These data sets are created just before DFSMShsm invokes DFSMSdss. VTOC copy data sets are not made when DFSMShsm dumps a DFSMShsm-owned volume.

The data set name of the dump VTOC copy is:

prefix.DUMPVTOC.Tssmmhh.Vvolser.Dyyddd

where:

prefix: Prefix you specified with the BACKUPPREFIX parameter of the SETSYS command.
DUMPVTOC
T
V
D: Constants.
ssmmhh: Time in seconds, minutes, and hours.
volser: Source volume serial number.
yyddd: Year and day.

With the following sample job, you can selectively copy all dump VTOC copy data sets to tape. These tapes can be taken off site as a group for use during the recovery and restore process.

           //DFDSSDUMP   JOB 'ACCOUNT #','NAME',MSGLEVEL=(1,1)
           //            EXEC PGM=ADRDSSU
           //SYSPRINT    DD SYSOUT=A
           //TAPE2       DD UNIT=3490,VOL=SER=DPVTOC,LABEL=(,BLP)
           //SYSIN       DD *
             DUMP DATASET (INCLUDE(prefix.DUMPVTOC.**))
                  OUTDDNAME (TAPE2)
