Explanation: RECOVER is an optional parameter specifying whether DFSMShsm prevents all recovery and restore processing or prevents only tape data set recovery processing. The RECOVER parameter, without any subparameters, specifies that all recover and restore processing tasks are prevented. No additional recovery and restore processing tasks are started. The RECOVER parameter prevents any request for backup data sets on a mounted tape volume.
| Subparameter | Explanation |
|---|---|
| TAPEDATASET | RECOVER(TAPEDATASET) specifies that tape recover and restore processing is prevented. No additional tape data set processing tasks are started. You can still perform recover processing tasks from DASD. |
The point at which DFSMShsm stops recovery processing is controlled by the ENDOFDATASET and ENDOFVOLUME parameters. WAIT-type command requests fail, and NOWAIT-type command requests remain queued.
Defaults: If TAPEDATASET is not specified, command recovery for both data sets and volumes is prevented.
