An Overview of nPartition Boot and Reset
Configurable Boot Settings
HP System Partitions Guide: Administration for nPartitions, rev 5.1 175
• 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 an nPartition
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 nPartition
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.
You can stop an nPartition from automatically booting, and instead
access the nPartition’s BCH interface, by typing a key within ten
seconds of the nPartition booting to BCH.
Primary Boot Path: 0/0/1/0/0.8
Boot Actions: Boot from this path.
If unsuccessful, go to BCH.

To discontinue, press any key within 10 seconds.
• Core Cell Choices
The core cell is the cell that “runs” the nPartition before it boots
HP-UX. A processor on the core cell serves as the monarch processor
that runs Boot Console Handler (BCH). The core cell is the one
whose core I/O is active for the nPartition.
