Well, start by doing Query PRocess and Query REQuest to see what may
be active for the volume.  Use Query LIBVolume to spot check, and
search back in the Activity Log to see what has been going on with the
volume.  Poke around and gather more info.

Context is lacking in the posting...  If an LTO volume, 8-character
volume names may be in effect, with L1 or L2 suffix characters.
