I have a tape showing in the scratch set of my media pool that has been removed from the tape library. It doesn't show up in the Device Manager. When the backup starts, I get a prompt to load that tape or a blank one. Also, if I select assign a tape to the scratch set I see tapes that have been removed from the tape library. Why is this happening and what can I do about it. I ran DBCheck and DBFix on the database but didn't find any errors. Does anyone have any suggestions?
