Boot Process for nPartitions, Cells,
and HP-UX
On HP nPartition servers, each partition’s cells go through the stages
described here when proceeding from being powered on or reset to
forming an nPartition (partition rendezvous) to booting the BCH
interface and booting the HP-UX operating system on a partition.
The boot process for nPartitions is similar to the process on other HP
servers. However, on HP nPartition servers, each cell boots and performs
self tests (POST) separately, and one or more cells rendezvous to form a
partition before providing a BCH interface for the partition.
Unique boot features of nPartitions include the ability to boot to BCH or
HP-UX when some of a partition’s cells are powered off, if a core cell has
booted in the partition. Likewise, inactive cells in a partition can be reset
and power cycled without affecting the rest of the partition.
