Robert, I do not understand your last sentence. Why would your z/VM systems crash? Is it because they are on DASD that is under XRC?

As I understand it currently, if our z/OS systems go with GDPS, and if and when they test the fail-over (which they want to do at least twice a year), both of my z/VM systems will crash. -- .~.
