Boot Process for nPartitions, Cells,
and HP-UX
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 an
nPartition before providing a BCH interface for the nPartition.
NOTE This section covers nPartitions booting HP-UX in non-vPars mode.
For details on Virtual Partitions (vPars), refer to the chapter Virtual
Partitions (vPars) Management on nPartitions on page 443.
