Hi,

¿It's necessary some commands when you boot the operating system after add the tow new CPU?

Thanks in avance.

No, nothing should be necessary after installing the additional CPUs. The system should see them and start using them automatically!

Hello,

Operating System must detect HW configuration automatically, no configuration needed.

The OS will not need anything, however the hardware may. These servers use Processor Support Modules to regulate voltages for the processors. The first 2 CPU's utilize PSM 0 and the second two CPU's utilize PSM 1. So, basically to upgrade to four CPU's you need to have two PSM's installed.

Another way to verify CPU configuration outside of the OS is to run the following from the BCH Main Menu:

> IN PR

--or--

> CO CPU

Or from the GSP: SS

Bob
