HP-UX System Administrator's Guide: Routine Management Tasks

2. Enter one of the following BCH commands (depending on your needs):
Example 2-13 Setting the PRI (Primary Boot Path) Using the BCH
Example: Set the primary boot path address to 0/0/0/2/0.5
Main Menu: Enter Command > pa pri 0/0/0/2/0.5
TIP: In the above command pa is a shortcut for the path command. In the Boot
Console Handler interface, you can often abbreviate commands and options (pri
for “primary”). See the help system in the BCH interface for acceptable
abbreviations.
Example 2-14 Setting the HAA (High-Availability Alternate Boot Path) Using the
BCH
Example: Set the high availability alternate boot path address to 0/0/0/3/1.6
Main Menu: Enter Command > pa haa 0/0/0/3/1.6
Example 2-15 Setting the ALT (Alternate Boot Path) Using the BCH
Example: Set the alternate boot path address to 0/0/0/3/0.6
Main Menu: Enter Command > pa alt 0/0/0/3/0.6
Example 2-16 Setting the ALT (Alternate Boot Path) Using the BCH
Example: Set the alternate boot path address to the lunpath hardware path

Booting PA-RISC Systems from an Alternate Boot Source
A boot source consists of two parts:
• A boot device containing a file system where kernel files are stored.
• A kernel file containing the kernel to boot.
Your primary boot source is a kernel file on your primary boot device. This is where
(if your system is set up for automatic booting) your system will boot from during an
autoboot.
You can override where your system boots from by manually interrupting the automatic
boot and specifying a different boot device or a different kernel file on your primary
boot device.
