Explanation: FROMVOLUME(volser)
is an optional parameter specifying the volume where the uncataloged
data set or data sets resided when DFSMShsm backed up the data sets.
You specify this parameter only if the data set was uncataloged. For volser, substitute the serial number of the volume where the
uncataloged data set or data sets resided when the backup versions
were created.
Defaults: None.
Note: - The data sets you specified should have been either all cataloged
or all uncataloged when DFSMShsm created the backup versions. If
the data sets were all uncataloged, they should have been on the same
volume. If the backup versions were not created from the same volume,
the backup versions of the data sets are not deleted.
- If you have cataloged and uncataloged data sets with
the same name, DFSMShsm deletes the backup versions of the cataloged
data set unless you specify the FROMVOLUME parameter. If you specify
the FROMVOLUME parameter, only the backup version of the uncataloged
data set is deleted.
- FROMVOLUME does not apply to SMS-managed data sets.
- FROMVOLUME does not apply to cataloged data sets.
