Do you have more than 1 system attached to the Tandberg library?

It sounds like the tape drive thinks that it is already in use by another system. 

If you are sure that the tape drive is not in use, and it is not currently busy, then a reset of the tape drive may be in order.  It may have just gotten confused.
