Accessing the Boot Console Handler (BCH)
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 3-4 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 has been powered on,
has completed all Power-On Self Tests (POST), and has proceeded to
BCH. 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.
The BCH interface’s HELP command lists BCH command or menu details.
