Hi,  Can I suggest a slightly different approach?

It's always been my understanding that when you use DRM and set the
value DRMBACKUPEXPIREDAYS to whatever, you should then not do DELETE
VOLHIST TYPE=DBB at all.  When the MOVE DRM is actioned to move the
tape form COURIERRETRIVE to ONSITERETRIEVE (having got the tape back
and checked it in) then the tape will be removed then from the volume
history automatically.

We make use of MOVE DRM wherest=VAULTRETRIEVE to get tapes back from
offsite, generate (using the cmd and cmdfile options) emails and
checkin commands to help the flow.

This is what we have done for years and it has worked very well for us.

Regards, Sheelagh
