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

NOTE: The boot device path that you specify in the setboot command (path in the
following examples) must be a valid HP-UX hardware path to a bootable HP-UX device.
Starting with HP-UX 11i version 3, the persistent DSF name and the lunpath hardware
path are valid entries to the setboot command, in addition to the legacy hardware path.
Regardless of the type of argument passed in input to setboot, setboot stores in stable
storage and displays in output an active lunpath hardware path to the device. This
lunpath hardware path may be automatically replaced by another active lunpath upon
failure of the initially configured lunpath. For more details, see the setboot(1M) in HP-UX
11i v3 white paper located on HP’s technical web site: http://docs.hp.com.
• Use the setboot -p path command, where path is a legacy hardware path, to
set the primary boot path, for example:
/usr/sbin/setboot -p 0/0/2/0/0.6
• Use the setboot -h path command where path is a lunpath hardware path,
to set the high-availability alternate boot path, for example:
/usr/sbin/setboot -h
0/5/1/0.0x50001fe15001eead.0x4001000000000000
• Use the setboot -a path command, where path is a persistent DSF, to set the
alternate boot path, for example:
/usr/sbin/setboot -a /dev/disk/disk13
Procedure 2-12 Setting the PRI, HAA, and ALT Boot Paths Using the Boot Console Handler
NOTE: A few older systems display elements in HEX. These systems are the rp4440,
rp3440, rp3410, and HP 9000 Superdome servers.
1. After powering on or resetting your computer (or nPartition) take control of the
boot process by hitting any key on the console keyboard so that
autoboot/autosearch will not boot the system automatically (if they are
currently enabled). The Boot Console Handler will display its main menu.
The Boot Console Handler (BCH) will display its main menu and prompt for a
command:
