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 !
