Hi

I think you wanna diable CPU. If yes then,

reboot the server and interrupt the boot process.
Enter the service menu with SER
Then enter
CPU x OFF
where x=the CPU number you wish to disable.

Hi (Again),

The best way may be uysing the EFI utility cpuconfig.

For details, check this thread:

Use cpuconfig from EFI:

fs0:\> help cpuconfig
Deconfigure or reconfigure cpus

CPUCONFIG [module [on|off]]
CPUCONFIG [threads [on|off]]
CPUCONFIG [pstates [on|off]]

module : Specifies which cpu module to configure
threads : Use to display info or configure threads
pstates : Use to display info or configure Power/Performance States (P-states)
on : Specifies to reconfigure a cpu module, cpu threads, or enable
P-states
off : Specifies to deconfigure a cpu module, cpu threads, or disable
P-states

Note:
1. Cpu status will not change until next boot.
2. Specifying a cpu number without a state will display
configuration status.

Examples:
* To deconfigure CPU 0
fs0:\> cpuconfig 0 off
Cpu will be deconfigured on the next boot.

Press ENTER to continue, 'q' to exit:
* To display configuration status of cpus
fs0:\> cpuconfig

1 2 1.1 GHz 4MB 32MB 1F/01 B1 Active

* To display cpu thread status
fs0:\> cpuconfig threads

cpuconfig: Threads are turned off.

* To enable cpu threads
fs0:\> cpuconfig threads on

cpuconfig: Threads will be on after a reset

* To disable cpu threads
fs0:\> cpuconfig threads off

Press ENTER to continue, 'q' to exit:
cpuconfig: Threads will be off after a reset

Keep in mind that cpuconfig on an rx2660 enables/disables an entire processor - ie both cores if it is a dual-core processor...
