BCH This procedure (BCH Main menu PATH command, and Configuration
menu PATHFLAGS command) configures an nPartition’s boot paths and
boot actions (path flags) through its BCH interface.
To list all boot path and action settings for an nPartition, you also can
use the BCH Information menu’s BOOTINFO command.
Step 1. Determine which devices will be used for booting HP-UX on the
nPartition, and determine the boot behaviors you desire.
You need to determine the hardware paths of all potential boot devices
that you will configure as the PRI, HAA, and ALT boot paths.
You also need to determine which device you want to boot by default (if
any), and which (if any) device you want to boot if the default device fails
to boot.
Typically, the PRI path is set to the default boot device and the HAA
path is set to the device you want to boot if PRI fails to boot.
Step 2. Log in to the service processor (GSP or MP), access the nPartition’s
console, and access the BCH Main menu.
From the partition console you access the partition’s BCH interface. If
the partition is not at the BCH interface you must either boot the
partition or shut down HP-UX to return to the BCH interface.
Step 3. At the BCH Main menu, set the boot path values using the PATH
command.
To list the current boot path settings, enter PATH with no arguments.
To set a boot path, enter PATH VAR hwpath , where VAR is the boot path
variable (PRI, HAA, or ALT) and hwpath is a boot device’s hardware
path.
For example, to set the PRI boot path to a new value (4/0/2/0/0.10, in this
case) enter PATH PRI 4/0/2/0/0.10, as shown below.
Main Menu: Enter command or menu > PATH PRI 4/0/2/0/0.10.0
Primary Boot Path: 4/0/2/0/0.10
4/0/2/0/0.a (hex)
Main Menu: Enter command or menu >
