Sorry, Lee; I misread your original post where you asked how RACF *protects* FCP disks. It doesn't. CP doesn't allow ESMs to control ATTACH/DEDICATE. (It's on the to-do list.) If they want RACF control over what guests can see the LUN, then they have to use EDEVs, since that's the only way to get minidisks, where the ESMs hold sway.
