Conﬁguring Boot Paths for a Partition

Each partition in an HP Superdome complex has three boot path

variables.

The boot path variables are: primary (PRI), secondary (HAA, the

“high-availability alternate”), and the alternate (ALT) boot device paths.

Typically, HAA is a mirror of PRI, and ALT refers to a DVD-ROM or tape

device.

This section describes how to set these variables.

BCH Use the following procedure to conﬁgure a partition’s boot paths through

its BCH interface.

Step 1. Determine the device path for the target boot device, and select which

boot path variable (PRI, HAA, ALT) will be conﬁgured with the target

boot device’s path.

Step 2. Access the partition BCH interface’s main menu and check the current

setting for the selected boot path variable (PRI, HAA, or ALT).

Check the setting by using the BCH menu’s PATH command, which can

be abbreviated as PA. For example, to display all boot path settings enter

PA with no arguments:

You can perform this task using the BCH interface or HP-UX

commands.
