	A few more points to follow-up my original posting:

o	Yes, I know about the "o" compatibility switch for rdump and
	rrestore.  It doesn't work when dumping from a 2.0 machine to
	a 3.1 machine, as far as I can tell.  (I assume it works the
	other way around.)  2.0 has no "o" switch at all.

o	I did manage to back up our VAX by doing:

		On VAX:		rdump 0uf server:/tmp/root.dump /

		On DS5400:	dd if=/tmp/root.dump of=/dev/rmt1h bs=10k

	Not ideal, but it works.  (But I cannot rrestore from the tape
	drive anyway... gotta go back to disk first, then rrestore from
	the file.)  :-(  

Still flailing...
