I was once granted access to, and crashability of, "a totally isolated test system" to test my sensitive supervisor state, key 0 code. I managed to cause JES2 on the test system to crash just after it had done a hardware reserve to its checkpoint data set, which, of course, was also shared by the production system. Thus I caused a lengthy non-optimal situation on the production system. My point is to examine every possible link between the two allegedly physically isolated systems with a high-powered magnifying glass and as a criminal trial lawyer would think; i.e., assume that the two systems have at least one link that you haven't found yet, guilty until proven innocent etc.
