Well, the answer to my question was extremely simple:
Do an interactive restore (i option) and start with
the last tape of the dump and work towards the first
(this was a multi-tape dump).

I would like to thank the following people for their prompt
responses which saved my butt!! I think everyone had the
same answer.

Hi all,

We have a large storage array (around 55 gig) for which
I use ufsdump to backup. This takes multiple tapes
(8mm 112 meter, Exabyte 8505 drive) to do a level
0 dump. Someone (not me!) accidentely deleted about
10 gig of data that I now need to restore from the
multiple tape, level 0 backup.

I try to restore by putting the first tape of the
backup in the drive and typing "ufsrestore xbyf 512
/dev/rmt/0cn <directory to be restored>". Everything
seems to work fine at this point, but after about
three hours (it must be near the end of the first tape)
I start seeing an error message repeated:

"Read error while trying to resynchronize"

All I can do at this point is <cntl>-c the ufsrestore
and tell it not to continue. The complete directory
structure and some of the files have been restored at
this point, but there is still a lot missing. There
are still three other tapes that were used for the
backup. Is there a way I can get the data off of them?
If I try to to a ufsrestore on anything but the first tape
I get an error message: "This is not volume 1 of the dump"

Any ideas??

Thanks for your help!! This list is the greatest!!
