It says: "A logical CPU is in the reserved state when it is in the level-2 configuration, is not available to be used to execute programs, and cannot be made available by issuing instructions to place it in the configured state" as opposed to a "standby" processor that *can* be made available, and "configured" processors that *are* available to execute programs. The LPAR configuration has fields for "initial" and "reserved" number of CPUs. My understanding is that "initial" is how many logical CPUs come online when you activate the LPAR, and that you can add logical CPUs upto the "reserved" without an outage of the LPAR. | Rob
