Alain, Yes, that used to be true ... VM would eventually end up allocating all the drives to the various MVS systems, then it could never get a tape drive back for its own use.
This is no longer the case ... the MULTIPATH feature implemented a few years ago in CA MIM for z/VM addresses this problem ... that's why I mentioned MULTIPATH in my original response. As Dennis mentioned ... there is ATS, but that is in fact a z/OS *only* solution, there's no component for z/VM.

As Denis says, I remember that CA-MIM was not able to share drives when V= M or MVS are lvl2. Is it still the case ? Alain
