We share our 3494 between 2 MVS systems and one ADSM (AIX) system.  We
automated the checkin process.  Each MVS system and the AIX system has a
separate volume name range.  We let a background script run that queries
the 3494 using mtlib commands to see what tapes are in "insert" status.
We then process the AIX range of tapes and issue checkins for those.  I
rarely if ever issue a manual checkin command.

You need to make sure that your CHECKIN commands on each server use
the
VOLRANGE parameter. When you put tapes in the 3494, they are placed in
the
insertion catagory and the first 'host' to grab them get them. So you
could
possibly checkin serverA's tapes in for serverB and write over good
data.

For my AIX TSM Server, I create a server script that has the CHECKIN
command
with all my parameters. I then schedule this in an admin schedule to
run
daily after I know the operators have done tape rotation. TSM won't let
you
actually schedule a checkin command, but you can imbed it in a script
and
schedule the script. Also, this is the only command I run to manually
check
tapes in...RUN CHECKIN (CHECKIN is my script name). This way I make
sure
that I'm not going to checkin some other servers' tapes.

We use a naming convention for out tape volsers. R00000-R99999 is for
the
AIX server, and M00000-M99999 is for our OS/390 systems.
