Thanks Jim!! Executed the command as suggested. The CPU status went from a plus '+' to a 'N' as expected and desired.
Thanks all!!

The removal of a physical CP will be blocked only if it would reduce the number of physicals below the number of currently online CPs in all active zones which use dedicated processors, plus at least one CP for the shared pool. LPAR will allow a zone which uses shared CPs and has more online processors than the number remaining in shared pool after removal to continue to run in this overcommitted state, but of course that is not optimal from a performance point of view, so we would recommend that you use the MVS CF CPU(x),OFFLINE command to reduce the number of online logical CPs in any zone so that it does not exceed the number of processors in the shared pool. One you do this, LPAR will not allow you to CF CPU(x),ONLINE to get back into an overcommited state. Jim Mulder z/OS System Test IBM Corp.
