I am sorry to say my friend that re-labeling does not suffice.  When you
"re-label" a volume in networker it does not write back over the labeled
block size set for that tape.  OHHH GOD HOW I WISH IT DID!  In fact I am
planning on putting in an RFE for this.  I mean if the Legato is a tape
backup software would it not be nice if you could tell it or check off an
option like "Re-write label."  That would just make to much sense.
Otherwise we have been doing the same thing you have.  Rewind tape tar some
data to it then have NetWorker re-label the volume.

   Why tar ?
   What's wrong with /etc/LGTOuscsi/erase ?
   man erase...

Well, some implementations of "mt" give an erase option and it does just that;
it erases the ENTIRE tape.  It is much easier to use tar or dd to overwrite
the beginning of the tape.

There was some discussion of this some months ago along with a
discussion of stinit.def on Linux servers.   I thought the consensus
was that if you wrote a tape under one stinit regime, then relabled
under a different stinit regime (e.g. I went from no stinit to the one
recommended for ait-3) that the new tape would be labeled with
the characteristics in place at the time of the new labeling.
Is that wrong?  (Whenever I put in a tape that was labeled under the
old stinit regime, Networker complained.   It has never complained about
relabeled tapes.)
