Introduction to nPartitions

The resources belonging to inactive cells are not actively used by a
partition. For a cell’s resources to be actively used the cell must boot and
participate in partition rendezvous.
Genesis Partition
The Genesis partition is the initial, one-cell nPartition created within
a server complex. The Genesis partition is just like any other nPartition
except in how it is created.
If your server complex has its nPartitions pre-configured by HP, you do
not need to create a Genesis partition.
However, you always have the option of creating a Genesis partition by
using the service processor (GSP or MP) Command menu’s CC command,
G option, to “wipe out” any existing nPartition definitions and start a new
complex configuration that includes only the Genesis partition.
You can use HP-UX utilities running on the Genesis partition as the
method for configuring all nPartitions in the complex. The Genesis
partition always is partition number 0.
When it is first created, the Genesis partition consists of one cell that is
connected to an I/O chassis that has core I/O installed. The Genesis
partition also must have a bootable disk (or a disk onto which you can
install HP-UX).
If HP-UX is not installed on the Genesis partition’s disk(s), you can boot
the Genesis partition to the Boot Console Handler (BCH) menu and from
that point install HP-UX. This installation requires either having access
to an HP-UX install server, or a CD-ROM drive (or DVD-ROM drive)
connected to the cell’s I/O chassis.
After you boot HP-UX on the Genesis partition, you can modify the
partition to include additional cells. You also can create other, new
nPartitions and can modify them from the Genesis partition or any other
partition running HP-UX.
Note that—once you create additional partitions—you do not necessarily
have to use the Genesis partition to perform your partition management
and configuration tasks.
