If you mean that you had to do it manually and would like it to be
done automatically, it can't. That's the nature of the beast. The SCSI
Pass-Thru driver is exactly that, pass-thru. I.e. the driver has no
knowledge at all about what device it is talking to (in this case the
robot of the Autochanger) and hence *cannot* configure automatically
(like for example the stape driver can), so you have to do it manually.

OK. I'm going to have to read more about this Pass-Thru thing, as I fail
to see how the system can recognize a device but fail to create a device
file that is useable by the system's own utilities...

The point is that the pass-thru driver does *not* "recognize a
device". I.e. it doesn't know what a robot is, or any other device for
that matter. That's why you need to manually create the device file and
tell it (the driver) all it needs to know.

(And actually, I hadn't created the working device file until immediately
prior to the previous post... And guess what -- it works with mtx, too! :-)

Great!

Thanks,

You're welcome. I'm glad that my comment helped you solving the
problem.
