Step 4. Reboot the nPartition to use the cells’ new configuration (the new use-on-next-boot
values).
If you have changed any cell use-on-next-boot settings for the nPartition then reboot the
nPartition in either of two ways:
• Use the Windows shutdown /r command to perform a standard reboot.
If you have only changed use-on-next-boot values from y to n, then perform a reboot.
Any cells set to not be used will still be assigned to the nPartition but will not be used
(will not rendezvous) in the nPartition.
• Use the Windows shutdown /r command to perform a reboot for reconfig.
If you have changed any use-on-next-boot values from n (do not use on next boot) to y
(use the cell on next boot), then you must perform a reboot for reconfig to allow the
currently inactive cells to reboot and rendezvous when the nPartition reboots.
Configure and deconfigure processors (CPUs)
You can configure and deconfigure processors from any cell that is assigned to an
nPartition. Deconfiguring a processor causes it to not be available for use by the cell or
its nPartition.
Whenever you configure or deconfigure processors, you must reboot the corresponding
nPartition for the configuration change to take effect.
NOTE Configuring and deconfiguring processors may be restricted based on any capacity on
demand (iCOD) or pay per use (PPU) contracts for the server complex.
Configure and deconfigure processors using the following procedure:
Configuring and deconfiguring processors (CPUs) [EFI shell]
From the EFI Shell environment, use the cpuconfig command to configure or
deconfigure processors in the local nPartition.
Step 1. Access the EFI Shell environment for the nPartition whose processors you want to
configure or deconfigure.
Login to the management processor and enter CO to access the Console list. Select the
nPartition console.
When accessing the console, confirm that you are at the EFI Boot Manager menu (the
main EFI menu). If at another EFI menu, select the
Exit option from the sub-menus until
you return to the screen with the EFI Boot Manager heading.
From the EFI Boot Manager menu, select the
EFI Shell menu option to access the EFI
Shell environment.
Step 2. Enter the cpuconfig command with no arguments to list the current processor
configurations for all cells assigned to the local nPartition.
Step 3. Use the cpuconfig command to change processor configurations for any of the cells
assigned to the local nPartition.
cpuconfig cell cpu off deconfigures the specified processor (cpu) on the specified cell
(cell).
