Explanation: ALLDUMPS and BACKUPCONTENTS(nn)
are optional parameters you specify to determine the existence of
all full-volume dumps and to determine the contents of the user volume
at the time of incremental backup.
- ALLDUMPS
- is specified to determine the existence of all volume dumps
and on which dump volumes the dumps exist for a single level 0 or
migration level 1 volume. The following information is provided for
each selected dump:
- Source volume serial number
- Copy pool dump generations
- Dump class
- Dump date
- Dump time
- Dump relative generation number
- Dump expiration date
- Volume serial numbers of the set of volumes containing the dump
- BACKUPCONTENTS(nn)
when used with the PRIMARYVOLUME(volser) parameter,
is specified to list the contents of the user volume when the latest
or next-to-latest backup of (volser) was made. For nn,
substitute a 0 or 1 to indicate whether the latest or the next to
latest backup volume table of contents (VTOC) is listed. A 0 (zero)
indicates the latest. A 1 (one) indicates the next latest.
The
listing is from the requested VTOC data set. If 0 is specified, the
listing represents the contents of the user volume at the time when
the last incremental backup was done.
BACKUPCONTENTS, when used
with the PRIMARYVOLUME(
volser) parameter, is not processed
for volumes that have not been incrementally backed up by DFHSM 2.3.0
or a subsequent release. This happens because the VTOC copy data set
is not on a migration level 1 volume for incremental volume backups
performed by previous releases of DFSMShsm. With the PRIMARYVOLUME,
the listing can include data sets that are not eligible for incremental
backup by DFSMShsm. In addition to information provided for this
variation of the command, the following information is provided:
- Data set name
- Data set organization
- Date of last reference to data set
- Data set creation date
Defaults: If you do not specify
a 0 or 1 for nn, the default is 0 (list the latest backup
VTOC copy data set). If you specify any value other than 0 or 1, the
default is 0.
Note: - BACKUPCONTENTS is meaningful only when volser is specified
with the PRIMARYVOLUME parameter.
- The BACKUPCONTENTS parameter is not equivalent to the DUMPCONTENTS
parameter.
- BACKUPCONTENTS is ignored when DUMPVOLUME is specified.
- ALLDUMPS is valid with PRIMARYVOLUME and VOLUME when specified
with volser and with BCDS.
- Since DFSMShsm does not handle partitioned data set members individually,
the entire partitioned data set will be listed.
