I am not sure if there are any specific tapes, but they do remain online for a while. They are attached to a AIX machine, i have check the errpt but could not find any thing special. They are 3590E and are being used in 3494. Do they need any hardware level service? Looking forward for any help "David N.

If AIX, check the errpt. If Windows check your event viewer. * How long do they work for after you make them available again? Do they break right away as soon as they use a tape, or it is specific tape(s) causing the issue. Bad Tapes can cause weird things to happen. * What kind of drives are they, and what kind of library are they in? Lots of things can cause a drive to go off-line. ----- David N.
