I have an Exabyte VXA-2 1x7 library. I have backup media assigned by day (Monday, Tuesday, etc) with two Thursday backup tapes. Monday is in slot 1, Tuesday slot 2, etc. Thursday tapes get swapped each Friday, ie Thursday1 taken out and offsite, and Thursday2 put in.
About every two weeks (this is the only pattern I can find) the device grabs the wrong media. It then continues to grap random media, though it successfully backs up every night. I suspect that it has something to do with the Thursday media, but am not sure what or how to fix it.
Any ideas are appreciated.
