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.
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.
5. Exit the console and MP interfaces when you are finished using them.
To exit the EFI environment press ^B (Control-B). This exits the nPartition console and
returns you to the management processor Main Menu. To exit the management processor,
enter 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:
Procedure 4-49 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.
1. Access the EFI Shell environment for the nPartition whose memory you want to configure
or deconfigure.
Log in to the MP 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 Exit from the sub-menus until you return to the
screen with the EFI Boot Manager heading.
From the EFI Boot Manager menu, select EFI Shell to access the EFI Shell environment.
2. Enter the dimmconfig command with no arguments to list a current summary of the
memory configuration for the local nPartition.
3. Use the dimmconfig command to change memory configurations for any of the cells
assigned to the local nPartition.
NOTE: When you deallocate a DIMM, all other DIMMs in the echelon also will not be used
the next time the nPartition boots.
dimmconfig cell dimm OFF deconfigures the specified DIMM (dimm) on the cell (cell)
indicated.
dimmconfig cell dimm ON configures the DIMM on the cell.
Use dimmconfig cell to display the DIMM configuration for a cell.
