Re: how to disable cpu

Hi,
Extract the bad CPU, the computer will start up normally without any change in its settings.
Just check its primary boot.

boot into PDC
go into service menu (ser)
then type "cpu" & you can disable the cpu by following the instructions, like

Re: how to disable cpu

if a CPU is definitely bad, all you have to do is reboot the machine. At the time of startup h/w test, it will mark it as bad and will boot w/o that CPU being presented to the OS.

Re: how to disable cpu

Hi

JUST re-booting the server will not necessarily disable the CPU. After all the error is LPMC (Low Priority Machine Code), This usually means a correctble error occoured.

I have recently dealt with rp8400 system with a faulty CPU that we had to maually disable (it was re-booted a few times without disabling the CPU).

Re: how to disable cpu

hi friends,

I disabled the cpu 0 at the pdc prompt and the system came up using the cpu 1 .
Since no expert was available at onsite to remove the defective cpu physically this was the only option.

The procedure is in the pdc prompt , got to configuration menu , by typing 'co'.

Then at the configuratio menu , type ' cpu 0 off' to disable cpu 0.Then do a power cycle of the server.

Thanks for all ur valubale suggestions

Re: how to disable cpu

I don't think you can disable a bad Monarch CPU, which I would expect to be CPU0. If that is the bad CPU, it needs to be replaced.
