CPU disabling

[Dave Forber]

I have a 6 CPU N-Class system, of which due to Oracle licensing only 4 should be running.

Digging around, I see that turning off CPU's on HP is not as 'easy' as other OS's in that it cannot be done online. I believe it has to be done via GSP?

Anyone got the procedure of what's needed please?

Hi Dave,

N class processor deconfiguration procedure:
--------------------------------------------
Boot or reboot the server(ctrl b then "rs") and interrupt the boot process when
prompted to hit press any key within 10 seconds. From the BCH Main Menu, enter
SER to get to the SERvice menu. The service menu command to
configure/deconfigure a processor is CPUconfig:

CPU ON|OFF

The server will need to be restarted with the "RESET" command for changes to
take affect.
