Hi,

yes, you can do it:

1. Reboot the system.

2. Interrupt the boot process within 10 seconds by hitting any key.

3. This will bring up the Main Menu prompt from the BCH.

4. Enter the Service command:

Main menu: Enter command> SER

5. Enter the CPUconfig command:

Service Menu: Enter command> CPUconfig [] [ON|OFF]

Where = [0|1] processor

6. Enter the RESET command to reboot the system:

Service Menu: RESET



Have you found what CPU is bad? And first of all are you sure that is the problem?
I wrote that about what happened to me but an analisys of core is needed to discover what is the reason of the problem.

Best regards,
Fabio

Hi Fabio,

Thank you for the cpu disable procedure.
Since I don't have support with HP, I have to determine the root cause and tell the top management to make budjet for the same, and get it sanctioned.

I am assuming that the problem could be due to one of the processor. Please check the below URL as to why I am suspecting CPU

Thank you all for the support !

Hi,

ok, I suppose that the problem is about a bad CPU, following too my experience of few days ago. But I would advise you to not wait more than this because the definitive answer about the reason of the problem should come by analyzing the dump by HP.

Best regards and good luck,
Fabio
