nPartition Administrator's Guide, Second Edition

Once you begin the HP-UX boot process and load ISL, the BCH interface is no longer available.
The BCH menus and commands for nPartitions differ slightly from the commands menus for
BCH on other HP 9000 server systems.
To display the current BCH menu and commands, type DI.
The BCH interface HELP command lists BCH command or menu details.

Extensible Firmware Interface System Boot Environment
On HP Integrity servers the system boot environment is provided by the Extensible Firmware
Interface (EFI).
EFI is available through an nPartition console interface before an operating system has booted
and after the cells have booted and performed nPartition rendezvous (to make the nPartition
active).
The EFI environment enables you to manage and configure the operating system boot process
for an nPartition. You also can configure some settings for the local nPartition, get information
about the nPartition and its server complex, and perform other tasks such as reboot.
The EFI boot environment has two main components:
• EFI Boot Manager — A menu-driven interface that enables to you configure and select boot
options. From the EFI Boot Manager you can load an operating system, reset the nPartition,
and configure various system boot and console options.
• EFI Shell — A command-line system boot interface that you can enter by selecting the EFI
Shell option from the EFI Boot Manager Menu.
Type exit to leave the EFI Shell interface and return to the EFI Boot Manager Menu.
The EFI Shell provides much of the same functionality as the Boot Console Handler (BCH)
interface on HP 9000 systems (PA-RISC systems).
For details on using the EFI Shell use the help command.
The following commands are supported for accessing and using the EFI system boot environment
for an nPartition:
• To access an nPartition console type CO from the service processor (MP or GSP) Main menu.
• To force console write access, type ^ecf (Control-e c f).
• To exit the console, type ^b (Control-b) to return to the Main Menu.
Windows Special Administration Console (SAC)
After an nPartition has successfully loaded Microsoft® Windows® Server 2003, you can access
a text-based Windows administration interface at the nPartition console.
