You can stop a partition from automatically booting, and instead
access the partition’s BCH interface, by typing a key within ten
seconds of the partition booting to BCH.
• Core Cell Choices
The core cell is the cell that “runs” the partition 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 partition.
One cell is selected as the active core cell for the partition when the
partition boots. By default, the lowest numbered eligible cell in the
partition is chosen. To be eligible the cell must: be active, have a
connection to functioning core I/O, and be assigned to the partition.
You can designate up to four core cell choices, which are considered
in the order you specify as candidates to be selected as the active core
cell for the partition.
If none of the core cell choices is eligible to serve as the core cell, then
the partition attempts to select a core cell using the default algorithm
(lowest numbered eligible cell).
When no active cell in a partition can be selected, the partition will
remain at a ready for reconfig state and cannot boot to BCH.
• Cell Use-on-Next-Boot Value
Each cell in a partition has an associated use-on-next-boot value that
determines whether the cell’s resources are used by the partition.
This setting does not affect the cell’s partition assignment. The
use-on-next-boot value only determines whether the cell is an active
or inactive member of the partition when the partition boots.
Primary Boot Path: 0/0/1/0/0.8
Boot Actions: Boot from this path.
If unsuccessful, go to BCH.
