I am having some problems with dumps on our Encore.  What I am trying
to do is put multiple level 1 dumps on the same tape.   The way I
do this is by first rewinding the tape, writing the 1st dump, rewinding
the tape, mt -f /dev/rmt20 fsf 1 (skipping over the first dump using
the no_rewind device), writing the 2nd dump, rewinding the tape, etc.....

I can restore the 1st dump ok, but trying to restore any of the others gives
me the following error:

	# mt rew
	# mt -f /dev/rmt20 fsf 1
	# restore iv 
	Verify tape and initialize maps
	Dump   date: Wed Nov 25 09:02:36 1987
	Dumped from: Thu Nov 19 12:57:03 1987
	Cannot find file dump list
	# 

Any ideas?  I would prefer if I could get this to work instead of having
to use 1 tape per dump (I am aware that I CAN'T put multiple level 0
dumps on the same tape -- my level 1 dumps are relatively small, though,
so all of my level 1 dumps WILL fit on one tape).

Thanks in advance,
