Lately more than in the past (however this has always been visible since tape support was first added) my tape library becomes quite confused as to which tape is in the library.
What I mean by this is when I swap tapes I always run an inventory job. Sometimes, the inventory job will not correctly update the name of a tape, and either show it as an unrecognized tape or show it as the old tape. Often times, I am then forced to run a catalog of the tapes, and other times still I must physically remove the affected tapes from the library, let it see the empty slots, then re-add the tape and re-inventory the slots. If I do not complete these steps, B&R excludes the tape due to retention (or not being in the correct media pool), and my tape job fails - which is very frustrating when it's 1TB through a VM, and has to start over again.
Figuring that perhaps my tape drive may be bummed out, I downloaded their utilities and ran some extensive diagnostics, which show no abnormal I/O concerns.
I'm using a Quantum Superloader 3, does anyone have any experience with this happening?
