How to get BE to use oldest or earliest allocated tapes
I am running BE 12.5 and have a library that holds 48 tapes. I run numerous jobs with several media sets, although I do not initially assign tapes to a media set. They get assigned as needed. The tapes are set to non-appendable until allocated and infinite overwrite protection. I do not have a media rotation - once a tape is used it is appendable in its media set until full and then it is removed and stored.
My question is, how do I get BE to select the oldest available or earliest allocated tape for a job from the blank or scratch media tapes? From what I have read it seems like it should do this, but instead it randomly selects tapes from the pool of available tapes (blank or scratch). As it is now, I have some tapes that sit in the library for long periods of time without ever being used.
Your ideas, suggestions, and advice will be appreciated.
