The FROMVOLUME and TOVOLUME parameters of the RECOVER command,
used when recovering non-VSAM data sets, have different results when
DFSMShsm recovers VSAM data sets:
- The FROMVOLUME parameter applies only to uncataloged data sets
and, therefore, is not used for VSAM data sets.
- For VSAM data sets not cataloged, the TOVOLUME parameter can specify
only a volume owned by the same catalog where the data set being recovered
is cataloged or will be cataloged. When you do not specify the TOVOLUME
parameter, DFSMShsm recovers the data set to the volume specified
in the current catalog entry. If no catalog entry exists, DFSMShsm
recovers the data set to the same volume from which DFSMShsm backed
up the data set.
