So, I just tried out my new tape library (Powervault 124T) and it worked for the first job I did. I erased some tapes, let that job finish, ejected the magazine, reloaded with some tapes that had data, I did an inventory on them, and while I thought it finished. It must not have. I ejected the tape magazine, changed tapes, and discovered there was one still in the drive, and the job was not doing anything. It was stuck.
I canceled it, said okay I’m going to re-run it, but now the drives shows locked & I can’t unlock it.
