Restoring a non-VSAM data set from a dump copy

If the target data set exists, DFSMShsm deletes the data set. DFSMShsm invokes DFSMSdss with the storage class name and management class name associated with the data set. DFSMShsm also passes the target volume serial number selected by the criteria mentioned in Selecting the target volume for physical dump copy restore. With the information that DFSMShsm passed to it, DFSMSdss then restores the data set to that volume.

Note: Use the FORCENONSMS keyword to recover the data set to a non-SMS managed volume.

If the target data set does not exist, DFSMShsm invokes DFSMSdss with the storage class name and management class name associated with the data set when it was incrementally backed up. If the data set does not have an incremental backup version, neither the storage class name nor the management class name is passed to DFSMSdss, and the data set may be restored as non-SMS-managed.

If you specified the NEWNAME parameter in the command and a data set with that name exists, DFSMShsm deletes the existing data set. DFSMShsm then invokes DFSMSdss to restore the NEWNAME data set. DFSMSdss restores the data set to the volume passed by DFSMShsm. If the restore is successful, DFSMShsm catalogs the restored data set.
