FROMVOLUME(volser) is an optional parameter that specifies that the data set was uncataloged and that it resided on the volume specified by the volser when DFSMShsm created the backup version. For volser, substitute the serial number of the volume where the uncataloged data set resided when DFSMShsm created the backup version.

If FROMVOLUME is used to direct DFSMShsm to restore a data set from a dump copy, the dump copy made from the specified volume will be used regardless of the catalog status of the data set when the dump copy was made. The data set will be restored to the FROMVOLUME specified and left uncataloged.

If the FROMVOLUME is not specified, the volume on which the data set is currently cataloged, or where an incremental backup version was found, is used to locate an eligible dump copy.
