Explanation: FROMVOLUME(volser) is
an optional parameter specifying that the data set was uncataloged
and that it resided on the volume specified by volser when
DFSMShsm created the backup version or dump copy. For volser,
substitute the serial number of the volume where the data set resided
when DFSMShsm created the backup version or dump copy. If FROMVOLUME
is used to direct DFSMShsm to restore a data set from a dump copy,
the dump copy made from FROMVOLUME specified is used regardless of
the catalog status of the data set when the dump copy was first made.
The data set is restored to the FROMVOLUME specified and left uncataloged.
Defaults: None.
Note: - The FROMVOLUME parameter applies only to data set recovery; it
does not apply to volume recovery. If you specify FROMVOLUME when
it does not apply, DFSMShsm ignores it.
- You must specify the FROMVOLUME parameter if the data set you
want to recover was uncataloged when it was backed up.
- DFSMShsm recovers only cataloged data sets unless you specify
FROMVOLUME.
- DFSMShsm does not catalog the recovered backup version or dump
copy when you specify the FROMVOLUME parameter.
- The FROMVOLUME parameter does not apply to VSAM data sets.
- If the data set does not exist on the target volume for the recovery,
automatic class selection routines are invoked to determine if the
data set should be recovered as SMS, if FROMVOLUME is not specified.
- If FROMVOLUME is specified, DFSMShsm recovers the data set as
a non-SMS.
