Subject: del volhist?

Hi,

I'm running tsm 5.5.1.1 on win64, did a backup db to devclass drm
(devtype=file),and wanted to delete only that one dbbackup so I issued:

tsm: server>del volhist todate=today t=dbb dev=drm ANR6978E DELETE
VOLHISTORY: Invalid device class UNKNOWN.
ANS8001I Return code 3.

but, yes the deviceclass drm does exist:

so, I must be doing something wrong, or is this a TSM error?
