I believe when amdump completes the tape is rewound but not ejected. Its not even rewound here Mitch. Since amanda uses the non-rewinding device, the only time a rewind command is issued is when it wants to verify its got the right tape to write to. amcheck does this, and amdump does at startup, but not again. Sorry. I should be more careful about what I believe at 2:30 AM. I've used a number of different tape types and not seen any problem that could be traced to leaving a tape in a drive. But Exabyte is a drive I've had very little experience with. I can verify that too, I've had zilch trouble from leaving the tape in the drive, using a Seagate 4586np changer with a 4 tape magazine. FWIW, once one of these changers is loaded, I found that an 'mt -f /dev/nst0 rewoffl' will in fact cause it to load the next tape after that one has been rejected. Interesting. I've seen different behavior from different changers, but I haven't seen this. Is this in gravity mode? -Mitch

It may be possible to 'adjust' this behaviour with one of those dip switches visible under a rubber plug in the top right side of the drawer carraige when the drawer is open. I have two drives that are very similar, and one does it, one doesn't. The docs you can dl and print are pretty ambiguous about this. The command will not cause it to recycle back to slot one however, when its reached slot 4, its end of magazine. -- Cheers, Gene AMD K6-III@500mhz 320M Athlon1600XP@1400mhz 512M 99.07% setiathome rank, not too shabby for a WV hillbilly
