I have a suspicion that 'restore' is broken somehow as I have a new tape
drive in our web server machine (SONY SDT-7000) and backups work without any
problems.  The problem occurs when we try to restore files as we lost a file
today, and bang, restore wouldn't work at all.  Below is a list of the
commands I did to test restore on a new clean tape to make sure it's not
something else:

www# dump -0u -a -f /dev/rst0 /usr/local
  DUMP: Date of this level 0 dump: Wed Mar 25 18:52:22 1998
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping /dev/rsd1s1e (/usr/local) to /dev/rst0
  DUMP: mapping (Pass I) [regular files]
  DUMP: mapping (Pass II) [directories]
  DUMP: estimated 84334 tape blocks.
  DUMP: dumping (Pass III) [directories]
  DUMP: dumping (Pass IV) [regular files]
  DUMP: 72.94% done, finished in 0:01
  DUMP: DUMP: 84372 tape blocks on 1 volumes(s)
  DUMP: finished in 389 seconds, throughput 216 KBytes/sec
  DUMP: level 0 dump on Wed Mar 25 18:52:22 1998
  DUMP: Closing /dev/rst0
  DUMP: DUMP IS DONE
www# mt -f /dev/rst0 rewind
www# restore -f /dev/rst0 -i
tape read error: No such file or directory
www#

So the last error confuses me.  I thought perhaps there was something broken
with the tape drive -- e.g. it not being able to read or something so I went
with tar and was able to write and read back from the tape drive which leads
me to determine 'restore' is not working, atleast not from the current
sources dated around 3/5/98 I believe.

Is there a known problem/workaround for this?

Thanks!
Jon
