May I work with 3 processor in a rp5470_?

[Sebastian Perez]

Hi, I need to know if I can have three processor working in a rp5470. Actually I have one.
And may I install them without shutdown the server rp5470. What about the rp5430, can I install another processor in a rp5430 without shutdown the system_? I heard about the Dynamic Processor Deallocate.....

You must shut down the system to add more processors. You can have any number from 1 to 4 processors in an rp5470, and either 1 or 2 processors in an rp5430.

1) In rp5470, you can have up to 4 processors working at the same time.

2) Yes, the system is capable of doing dynamic processor deallocation with HP-UX 11 loaded. You can remove a working CPU when the system is online.

3) In rp5430, you can have up to 2 processors.

4) Even in rp5430, dynamic processor deallocation is supported.

Read about dynamic processor deallocation here:

These are the rp54XX product details:

Hi,

when you add third processor to the system,
you should have second Processor support
module present in the system. One PSM
supplies power to 2 cpus.

Hi Shiju,

I stongly feel you cannot plug in a processor
when system is live. The dynamic processor
deallocation feature may be for the processor
already plugged.

Not sure, can some one from HP clarify??

I personally would not plug another processor into a live system purely from a saftey aspect :-) John.
