   mt -f /dev/nrst0 fsf 1

   This will fast-forward past the first dump file one the tape and
   leave you at the beginning of the second file.

Note that something this will sometimes place you right before the start
of a secondary end of file marker.  The main way you know this is that you
will do the above 'mt' command and then try to do a restore and get an end
of file error.  Of course, the tape is now sitting beyond the EOF and the
restore, if attempted again, will probably work....  assuming that you
actually put a second file on the tape.

This sort of thing happens to me on my DDS2 drive.
