Obtaining dump volume information

You can request information about all dump volumes or specific dump volumes. In addition, you can select the volumes with specific characteristics. The forms of the requests for information about dump volumes are:

LIST DUMPVOLUME

LIST DUMPVOLUME -
   SELECT(AVAILABLE)

LIST DUMPVOLUME -
   SELECT(UNAVAILABLE)

LIST DUMPVOLUME -
   SELECT(EXPIRED)

LIST DUMPVOLUME -
   SELECT(UNEXPIRED)

LIST DUMPVOLUME -
   SELECT(NORETENTIONLIMIT)

LIST DUMPVOLUME -
   SELECT(DUMPCLASS(class))

LIST DUMPVOLUME(volser)

The first form of the request obtains information about all the dump volumes in the system. The next six forms of the request obtain information about all dump volumes in the system that meet certain conditions. The eighth form obtains information about all dump volumes in a group of volumes made from the same DASD volume from one dump operation. The variable volser can be any of the dump volumes in the group.

You can determine the data sets that were on a particular volume when the volume was dumped. The commands to do this are:

LIST ML1(volser) BCDS ALLDUMPS

LIST PRIMARY(volser) BCDS ALLDUMPS

LIST DUMPVOLUME(volser) -
   CONTENTS

The first two commands give lists of the volumes to which the source volume has been dumped and the date of the dump. The third command lists the contents of the source volume when it has been dumped. You can specify any one of the dump volumes in the set of dump volumes for volser for a particular date.

If a volume is processed by both full-volume dump and incremental backup, DFSMShsm maintains VTOC copy data sets for both operations. To determine the most up-to-date copy, issue the following command:

LIST PRIMARYVOLUME(volser) BCDS

If the full-volume dump is more recent than the backup, use the three preceding dump-related commands to obtain the latest VTOC copy. If the backup was more recent than the dump, use the LIST command for BACKUPCONTENTS as indicated in Obtaining DFSMShsm-managed volume information.
