My understanding is that MWV on a fullpack or devno minidisk that starts on cyl0 will let VM push the Virtual R/R through the hardware to the real R/R bit on the device. Is this still correct? I specifically chose this approach so that I could start building my new VM systems 2nd level on my production VM systems, and share the production RACF database with the 2nd level VM test/maintenance systems. I was trying to get away from a dedicated maintenance/test LPAR - which is what is required with DEDICATEed shared RACF database volumes. -- Jay Brenneman
