Regrettably absent is the ability of CP to perform standard (and common extension) inquiries of a remote LUN without having to ATTACH it to a guest. I.e. CP QUERY LUN 5 WWPN xxxxxxxxxxxxxxxxx DETAILS. Right now, LUNs are very much like tape drives: they have to be attached to a guest that knows how to talk to it in detail in order to get useful information out of it.
