Conﬁguring Boot Actions for Partition Boot Paths

Each boot path for a partition has associated with it a boot action. The

boot actions are set through path ﬂags, which can be set to the following

values:

• 0—Go to BCH (Boot Console Handler).

• 1—Boot from this path. If unsuccessful, go to BCH.

• 2—Boot from this path. If unsuccessful, go to the next path.

• 3—Skip this path and go to the next path.

The order of boot paths is: PRI, then HAA, then ALT. When a partition

boots, the partition attempts to perform the boot action for the PRI path

(and the HAA and ALT actions, as needed).

NOTE Following a self-test failure, a partition references its boot actions only if

the partition’s AUTOSTART value is set to ON.

BCH Use this procedure to set the boot actions for a partition’s boot paths.

Step 1. Log in to the Superdome complex’s GSP, access the partition’s console,

and access the BCH conﬁguration 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.

From the BCH main menu, enter CO to access the BCH conﬁguration

menu.

Step 2. List and set the path ﬂags (boot actions) for the partition’s boot paths.

Enter the PATHFLAGS command with no arguments to list the current

boot path settings and their path ﬂag settings.

Enter PATHFLAGS

path value

to set the path ﬂag value for the speciﬁed

boot path. The path may be PRI, HAA, or ALT, and the value may be 0–3.

You can perform this task using the BCH interface.
