     If you check them out, yes, they do not show up in a "q libvol" but
     they will still show up in "q vol". If a restore/retrieve is issues
     against one of these tapes a request will be seen of "Offline media
     needed for recovery/restore blah blah Please checkin volume blah into
     library blah" I believe is close to the wording... (in my aix 4.1
     environment)
     When the media is worn out, upon initial data checks I
     "MOVE DATA volumeserialnumber stg=sameorotherpool"
     then do a delete volume blah this allows me to then use the tape for
     target practice, or a kite tail...
     When the libr is full, I set the reclamation to 65 or so in hopes of
     getting 2 of three tapes back and order an expansion cabinet for the
     library... with the 4mm you might have to get another library and
     define a 2nd storage pool... early implementation I used 2 8mm librs
     and had diskpool1's nextpool =-> tapepool1 and
             diskpool2's nextpool =-> tapepool2
     because you can't spread a single storage pool across libraries...
     now I have an IBM3494ATL w/ IBM3590Magstar drives... I just hit the 2+
     terabyte data quantity and have another S10 storage cabinet waiting to
     be installed... it will be another 2 weeks until the tapes get in
     (sigh) so I'm finding @ week old archives with the longest keep to's
     to check out and check in scratch volumes... but the influx of data is
     around 100 GB a night but old data expires, reclamation kicks off, and
     I play musical tapes again....
     later
          Dwight

I have a question that has no doubt been answered by someone in the past,
but I haven't seen it.  I have a 4mm tape robot that has all of it's tapes
more or less full.  I want to checkout tapes, then checkin new ones. When
I do this the tapes that no longer appear in the libvolumes are unavailable
for restoring files.  What can I do so that I am prompted for these tapes?
I also have a single tape 4mm drive.  I would really like to associate
these volumes with the single drive so that when the tape is needed, I can
mount it on a punctual basis and leave the robot alone.   Any suggestions?

What do others of you do when your robot's media is all full? or worn?
