A customer asked me today how she could find out what the maximum allowable virtual storage size was for a given guest (without looking at the CP directory entry). The only thing I could think of was CP DEFINE STORAGE <reallybignumber> and seeing if it fails. Of course, that carries a risk: if you happen to hit a value that *is* allowed, you get to reIPL.
Is there another way? QUERY VIRTUAL STORAGE MAX or something would seem like a reasonable extension... ...phsiii
