nPartition Administrator's Guide, Second Edition

1. Access the BCH Main Menu for the nPartition whose memory you want to configure or
deconfigure.
Login to the service processor (MP or GSP) and enter CO to access the Console list. Select
the nPartition console. When accessing the console, confirm that you are at the BCH Main
Menu (the Main Menu: Enter command or menu> prompt). If at a BCH menu other
than the Main Menu, then enter MA to return to the BCH Main Menu.
2. Enter SER to access the BCH Service Menu.
3. From the Service Menu, use the DIMMDEALLOC command to list the current configurations
of memory modules (DIMMs) in the cells assigned to the local nPartition. Also use the
DIMMDEALLOC command to configure and deconfigure DIMMs for cells in the local nPartition.
NOTE: When you deallocate a DIMM, all other DIMMs in the rank or echelon also will
not be used the next time the nPartition boots.
Enter DIMMDEALLOC with no arguments to list the current DIMM configurations for all cells
in the local nPartition.
DIMMDEALLOC cell dimm OFF deconfigures the specified DIMM (dimm) on the cell (cell)
indicated.
DIMMDEALLOC cell dimm ON configures the DIMM on the cell.
Use DIMMDEALLOC cell to display the DIMM configuration for a cell.
Enter HELP DIMMDEALLOC for details.
4. Reboot the nPartition using the REBOOT command.
Whenever changing memory configurations you must reboot the corresponding nPartition
to allow the configuration changes to take place.
5. Exit the console and service processor interfaces if finished using them.
To exit the BCH environment type ^B (Control-B); this exits the nPartition console and
returns to the service processor Main Menu. To exit the service processor, type X at the Main
Menu.
Procedure 7-15 Configuring and Deconfiguring Memory (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. The EFI Shell is available
only on HP Integrity systems.
1. Access the EFI Shell environment for the nPartition whose memory you want to configure
or deconfigure.
Login to the service processor (MP or GSP) 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.
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.
