Issue/Introduction

Is there a command or a screen that will show if  product Disk Backup and Restore - MVS is used?

Resolution

Try to do the console command: S DMSAR,DMSAR=STATUS. If there is a reply to it and no JCL error message then Disk is running

The DMSAR STATUS shows if the SVC hooks are installed for auto restore (DMSAR). 

The DMSAR STC would be running for any Disk function usage, for a short duration. Otherwise the output queue may show the task. The started task is used for the auto restore function.  All other jobs are batch jobs.

If the SVC hooks are not installed it is still possible to use Disk without auto restore but it is not common because then the RESTORE would always be required through a batch job.

Executing a batch job for a  LISTV or LISTD would determind if Disk is available.

Another idea would be to look at automation scheduling tools to see if they have regular scheduled jobs that reference Disk functions like backup / archive.
