Boot Console Handler (BCH) Access

Each nPartition in a server complex has its own Boot Console Handler

(BCH) interface. When an nPartition is booted to BCH, its BCH interface

is available through the nPartition’s console.

The nPartition BCH interface enables you to manage and conﬁgure the

HP-UX boot process for an nPartition. You also can conﬁgure some

settings for the local nPartition, get some information about the

nPartition and its server complex, and perform other tasks such as

reboot.

Figure 3-3 shows details on accessing and using an nPartition’s BCH

interface, including the following points:

• To access an nPartition’s console type CO from the service processor

(GSP or MP) 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.

The BCH interface is available after an nPartition’s cells have been

powered on; its hardware has completed all Power-On Self Tests (POST);

and the cells have booted past boot-is-blocked, rendezvoused, and BCH

has started executing. Refer to the chapter An Overview of nPartition

Boot and Reset on page 161 for details.

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’s HELP command lists BCH command or menu details.
