Q DRM returns empty list

[mirrorsaw]

Hi everyone,
I noticed today that one of my SP8.1 servers is not automatically clearing down old DB backups, but worse yet, when I run Q DRM it shows an empty list and "ANR2034E QUERY DRMEDIA: No match found using this criteria."
We run DB backups to disk every day, and they complete successfully , I can see all of the DBV files sitting on the drive so they definitely exist.
I feel like if I can solve the mystery of the empty DRMEDIA list, that will also solve my problem with these DBV files never expiring.

Here is DRMSTATUS for a working server:
Plan Instructions Prefix:
Replacement Volume Postfix: @
Primary Storage Pools:
Copy Storage Pools:
Active-Data Storage Pools:
Container Copy Storage Pools:
Not Mountable Location Name: NOTMOUNTABLE
Courier Name: COURIER
Vault Site Name: VAULT
DB Backup Series Expiration Days: 4 Day(s)
Recovery Plan File Expiration Days: 60 Day(s)
Check Label?: No
Process FILE Device Type?: Yes
Command File Name:

and DRMSTATUS for my broken server:
Plan Instructions Prefix:
Replacement Volume Postfix: @
Primary Storage Pools:
Copy Storage Pools:
Active-Data Storage Pools:
Container Copy Storage Pools:
Not Mountable Location Name: NOTMOUNTABLE
Courier Name: COURIER
Vault Site Name: VAULT
DB Backup Series Expiration Days: 4 Day(s)
Recovery Plan File Expiration Days: 60 Day(s)
Check Label?: No
Process FILE Device Type?: No
Command File Name:

The only difference I can see is 'Process FILE Device Type'?

OMG solved my own problem in a matter of minutes, how embarrassing , the issue indeed was that I needed to run SET DRMFILEPROCESS YES

Maybe this post will be useful to future generations
