It looks like the tape drive itself is detected, and is /dev/st0. If
I am reading the specs correctly, it has a four tape magazine. The
error on lun 1 is probably the response from the tape changer that
the kernel does not understand. I don't think the kernel supports
tape changers directly, but there are some user space programs that
support some changers. You will have to see if yours is supported.
Take a look at the mtx package.

You can check the drive itself using the mt command. (mt-st package.)
