Hmm, I guess I'm used to changers where the tape mechanism and the changer mechanism are relatively separate. In most cases the changer has little idea about what type of tape it put in the drive. The only thing it might know is an id from a barcode label. Your changer is evidently different, as the error below suggests -- it indeed came from the changer LUN on the device. > > only reason you would have gotten an error message that a cleaning tape was > > installed would be in response to a command to the tape drive. > > > Well... i didn't have the time today to attempt to debug this > properly but i did turn on cam debugging and tried to reproduce it, > and surely enough the same thing happened again. here's what it said: > > # camcontrol debug -I -T -S -c 0:4 > Mar 1 19:23:21 src /kernel: (ch0:ahc0:0:4:1): MODE SENSE(06).

From the logs above, it looks like you tried to move the tape into the drive twice. Note that the first and second move medium commands are identical -- i.e. same source and destination. So is that what happened? Once a tape drive has ejected a tape, I'm not sure if you can push the tape back in the tape drive without first moving it back to a slot or something. If you wanted to put it back in the drive, you'd probably have to do something like: chio move drive 0 drive 0 But I kinda doubt that would work. I'm surprised it gave the error it did, though. I would expect something like "source element empty" or "destination element full". > and it reports itself as a `HP C1553A 9608', does someone have the > same drive who could also try this? > > > My guess is that your problem is that your autoloader is configured in > > autoloader mode instead of changer mode or something. > > > Hmm i didn't have the sucker's manual handy to check this, so > at the moment i can only say that chio does work on it with > regular tapes...
