cpuconfig cell cpu on configures the processor on the cell.
Enter help cpuconfig for more details on configuring and deconfiguring processors
from the EFI Shell.
Step 4. Reboot the nPartition using the reset command.
Whenever changing processor configurations you must reboot the corresponding
nPartition to allow the configuration changes to take place.
Step 5. Exit the console and management processor interfaces if finished using them.
To exit the EFI environment type
^B (Control-B); this exits the nPartition console and
returns to the management processor Main Menu. To exit the management processor,
type X at the Main Menu.
Configure and deconfigure memory (DIMMs)
You can configure and deconfigure memory modules (DIMMs) from any cell that is
assigned to an nPartition. Deconfiguring memory causes it to not be available for use by
the cell or its nPartition.
Whenever you configure or deconfigure memory, you must reboot the corresponding
nPartition for the configuration change to take effect.
NOTE DIMMs operate either in ranks of four or echelons of two, depending on memory
architecture of the server. When you deallocate a DIMM, all other DIMMs in the rank or
echelon also will not be used the next time the nPartition boots.
Each rank or echelon is numbered (0, 1, 2, and so on up to hexadecimal number F as
needed). The DIMMs in the rank or echelon are lettered (A to D). For example, rank 0
includes DIMMs 0A, 0B, 0C, and 0D; echelon 1 has DIMMs 1A and 1B.
Configure and deconfigure memory using the following procedure:
Configuring and deconfiguring memory (DIMMs) [EFI shell]
From the EFI Shell environment, use the dimmconfig command to configure or
deconfigure memory modules (DIMMs) in cells assigned to the local nPartition.
Step 1. Access the EFI Shell environment for the nPartition whose memory 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 dimmconfig command with no arguments to list a current summary of the
memory configuration for the local nPartition.
Step 3. Use the dimmconfig command to change memory configurations for any of the cells
assigned to the local nPartition.
