Sounds like the Ultrix partition information is bad, or that NetBSD
isn't reading it correctly.   Can you boot Ultrix and send us the
complete output of the following command?

	chpt -q -v /dev/rrz2c

Try using

	dd if=/dev/tz0 of=/tmp/tape-file bs=16k

cp isn't a good choice for reading raw block devices.
