If the system fails with an HPMC and one of the CPU modules is suspect, you can deactivate

its CPU online temporarily. The online diagnostic STM has the Expert Tool and it provides

you the ability of the online CPU deactivation. And also you can mark the CPU to be

deconfigured and it will be deconfigured at the next system boot.



1) Check the CPU status with the HP-UX command "top".



2) Run STM. You can sue CSTM/MSTM/XSTM.



3) Install HP Only password. (System -> License -> Install HP Only...)



4) Run CPU Expert tool. You need to select one CPU at least.

1. Select a line of CPU on the map.

2. Tools -> Expert Tool -> Run



4) Select "Options" in the Expert Tool Menu.
