Configurable Boot Settings
You can configure the following boot settings for each partition.
• Boot Device Paths
You can set boot device paths to reference the hardware paths where
bootable devices reside within the local nPartition.
The boot device paths include the primary boot device (PRI boot
path), the high-availability alternate device (HAA boot path, such as
a mirror of the root volume), and the alternate device (ALT boot path,
such as an install or recovery device).
The PRI path is the default device booted by the BCH interface’s BOOT
command.
You can set boot paths using the BCH interface, the parmodify
command, and Partition Manager. The setboot command can set the
PRI and ALT paths only.
• Boot Actions
Each boot device path has an associated boot action, which is
established by the path’s “path flag” setting. The boot actions (path
flag settings) are referenced automatically when a partition initially
boots to the BCH interface.
Boot actions have no effect on boot behavior when you manually boot
HP-UX using the BCH interface’s BOOT command.
The boot action for the PRI boot path establishes what the partition
does when it boots and first reaches the BCH interface: boot the PRI
device, go to the BCH Main menu, or skip the PRI path and attempt
to perform the HAA path’s boot action. You also can specify what
action to take if an attempt to boot a device fails (either go to BCH, or
try the next path).
Depending on the PRI path flag setting, the HAA boot action may be
referenced. Likewise, the HAA setting determines whether the ALT
boot actions may be referenced.
You can set boot actions using the BCH Configuration menu’s
PathFlags (PF) command. The setboot command can configure only
the PRI actions from HP-UX.
For details use the BCH Command menu’s HELP PF command.
