Question 1:
- are you operating a medium changer ? A medium changer is a device
which can automatically load, remove and choose from different
cassettes.
if no: well, why are you using mtx, then ?
Question 2:
- if you answered YES to the first question, are you 100% sure that
your tape device has LUN (Logical Unit) 0 as the tape drive, and
1 as the changer ? (if you don't know, look in the debug messages,
or do a scsi-probe/probe-scsi/sprobe/whatever from PROM monitor
after clean shutdown).
If you do not have such changer, you need other software. I have software
for Solaris, including full source, which can be used to control a
SCSI ID-based autochanger (such as the DILOG Libra series, from
the company I work for, thank you for reading this subliminal
advertising :)).
Look at http://www-internal.alphanet.ch/archives/local/autochangers/plt/
this works under Linux (through sg) and Solaris (see README.Solaris)

Presumably there is no LUN 1.
