I missed this first time around - it sounds like the device is reporting
that it's a direct access (ie disk) device at the SCSI level. Do you
know if this tape drive has ever worked on any operating system?
As far as using a working tape drive, something like:
tar cf /dev/nrst0 file ...
mt -f /dev/nrst0 offline
should work.

That's a NetBSD/pmax restriction because of the old SCSI driver.
However, the driver will detect it as a disk drive if that's what the
device wants to advertise itself as.
