An Overview of nPartition Boot and Reset
Configurable Boot Settings
HP System Partitions Guide: Administration for nPartitions, rev 5.1 174
Configurable Boot Settings
Each nPartition has its own collection of boot-related settings that
specify which hardware manages the boot process (the core cell), how the
boot process proceeds (automatically boot HP-UX, or wait for BCH
commands), and whether cells are configured as active cells when the
nPartition boots.
nPartition boot settings are stored as part of the server Complex Profile
data.
You can configure each nPartition’s boot settings by using the
nPartition’s BCH interface or by running HP-UX utilities on the
nPartition.
By using the parmodify HP-UX command or Partition Manager, you also
can configure some boot settings for remote (non-local) nPartitions in the
same server complex.
You can reconfigure boot settings at any time to change the nPartition’s
boot behavior, specify different boot devices, or adjust settings based on
nPartition configuration changes. Some boot setting changes require
rebooting to take effect.
Also see Checklist and Guidelines for Booting nPartitions on page 184 for
details on ensuring a bootable nPartition configuration.
You can configure the following boot settings for each nPartition: boot
device paths, boot actions, core cell choices, cell use-on-next-boot value.
• 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.
