I wish everyone wishing help would be as thourough as you.
I suspect that the problem lies in mtx. It is a very fragile program as Peter
has pointed out. I'd recommend that in the "loaded)" section of mtx-changer,
you put a "mtx -f $ctl status" (or whatever is the correct syntax) just
before the one that obtains the loaded status, then ignore the return code
from that call. Leave the existing call to mtx after the new one you add.
Hopefully, this will have the effect of clearing the error status from the
SCSI channel.
You might also check to ensure you are using the latest mtx version, though
since you are using FC3, I think you are OK.
