Re: MVS + ADSM on 3494

     I use exit CBRUXENT, there is a sample exit in SYS1.SAMPLIB(cbrspuxe).
     The exit gets control for each tape inserted in the ATL.  My mainframe
     tapes have serial numbers that start with A and my AIX tapes have
     serial numbers that start with B.  For tapes with a serial number
     starting with A the exit sets the return code to 0 (insert the
     cartridge into the tape library), for tapes that start with B the exit
     sets a return code of 12 (LEAVE THE CARTRIDGE IN THE INSERT CATEGORY
     X'FF').  The tapes in X'FF' status then need to be labeled and checked
     in to ADSM on the AIX system.  As was mentioned in another reply, you
     need to use different scratch and private codes for the tapes.

My customer has an IBM 3494 Library, that used to be dedicated to a MVS.

I was able to share this library with a NetFinity running Adsm Server,
and it all seemed to work very well until today. The guy that was in
responsible for MVS Backups told me that the number of MVS tapes had
increased but he hadn't added none. I had added some for ADSM !

We did some tests, and despite of the category of ADSM tapes (that were
far different from MVS tapes), the MVS was able to pick some of my tapes
and to backup on them ! I can4t use MVS tapes but MVS can use mine !

Even worse, when MVS requested a tape tht was already in use by ADSM,
the program that requested the tape crashed (Abend!) ! You can imagine
what a thing like that can do to a huge batch processing ?!

Does anyone know how to really separate the tapes between these two
systems ?! A don't know for how long MVS will keep working without
picking up ADSM tapes !

Thanks All !
