That all sort of makes sense. However, I would question either the reboot procedure or the hardware manufacturer. My library is a totally different sort. It is a Sony LIB-162A5BBLE. The instructions regarding shutting it down or "rebooting" it are very specific about the procedures. I have to initiate a shutdown from the front panel. It secures everything (ejects tapes, repositions physical components) and then gives me the go ahead to power it down. At that point I can flip the power switch on the backside. If Quantum/HP suggest/allow simply powering things off and result in tapes being messed up, or if their shutdown procedure fails to eject tapes, then that is just wrong. It's good that they tell you now, so you have a safe workaround, but that should be built in to standard operating procedures. Just my 2 cents. --------------- Chris Hoogendyk - O__ ---- Systems Administrator c/ /'_ --- Biology & Geology Departments (*) \(*) -- 140 Morrill Science Center ~~~~~~~~~~ - University of Massachusetts, Amherst <[EMAIL PROTECTED]> --------------- Erdös 4 ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
