1. Check the Actions pending field for any actions marked Y. DFSMSrmm cannot return the volume to scratch status until all other release actions have been completed.
2. Check the Store Information Intransit field. If Intransit is Y, the volume is moving from one location to another. The volume must return to a library location or its home location before DFSMSrmm can return the volume to scratch status.
3. Use the RMM CHANGEVOLUME CONFIRMMOVE command when the pending volume move has been completed.
4. Run DFSMSrmm inventory management to complete the volume's move to its home location.

If Intransit is N, the destination field is blank and the volume is in a library location or its home location, then the volume should return to scratch during the next EDGHSKP EXPROC processing.

If Intransit is N, and the volume that is in an automated tape library dataserver and has a destination to a location outside the automated tape library dataserver, you can either cancel the move, or eject the volume and confirm the movement.

If the volume is system-managed, DFSMSrmm will not change the status of the volume from master to scratch if the update to the TCDB fails. The system running inventory management processing must have access to the TCDB. Check for error messages in the DFSMSrmm MESSAGE file.

If your installation uses the DFSMSrmm EDG_EXIT200 exit, check this exit because it could prevent the volume from returning to scratch. You can determine whether there is any active exit for EDG_EXIT200 by checking the messages in the MESSAGE file.
