This message is issued to the dump activity log when a fast replication backup volume is successfully dumped to tape. Because the volume that was dumped (frbvol) is a fast replication backup volume, the dump tape that was produced (tapevol) actually represents the source volume (srcvol) that the backup volume was a backup for.

Even though DFSMShsm records will indicate that tape tapevol is a dump of volume frbvol, the dump tape cannot be used to recover backup volume frbvol. Rather, it can be used to recover the source volume srcvol.

See z/OS DFSMShsm Storage Administration for more information.
