This page presents an overview of the create nPartition
wizard.
For a guide to nPartition configuration
requirements and recommendations, refer to the configuration guide.
To begin the create nPartition wizard, select
nPartition Create nPartition
from the actions menu. This action can be
selected from any scope. You do not have
to select any objects from the current view before starting the wizard. However, if
the current view includes any selected free
cells, then those cells will be pre-selected to be assigned to the new
nPartition. You can change this selection in the second step of the wizard.
For more information about scope, views, actions, and selecting objects, refer to
the overview help page.
Creating nPartitions
nPartitions provide both hardware and
software isolation between different instances of an operating system
running on a single server system. Each nPartition consists of an assigned group
of cells (containing CPUs and memory), and
I/O chassis (through which peripheral devices can be
attached).
When you create an nPartition, Partition Manager steps through the process. At each
step, a dialog is presented that allows you to specify the information needed to
complete that step. Help is available at each step, and at any time you can back
up to previous steps, or cancel out of the wizard. At each step, reasonable
default values are provided, although these defaults may not be the optimal
choices for your nPartition.
Steps of the Create nPartition Wizard
The create nPartition wizard consists of the following
steps.
Specify the partition name of the new nPartition.
Select the cells that will belong to the nPartition.
Set optional attributes of the cells in the nPartition.
Request the mix of interleaved memory and
cell local memory (CLM) to be used by
the nPartition at boot time.
Cell local memory is only supported on nPartitions
running HP-UX 11i v2 (B.11.23), SuSE Linux Enterprise Server 9, or Microsoft® Windows®.
Also specify whether Hyper-Threading
is enabled for the nPartition, if its cells have processors that support Hyper-Threading.
Choose whether the nPartition will automatically boot to the system
firmware user interface once it has been created, or will be
booted manually later.
Review a summary of the nPartition's configuration, along with the results of
a set of high availability checks.
Preview the command that will be executed to create the nPartition, along with
any additional steps that should be followed after the nPartition is created.
The nPartition will be created at the end of this step.
Messages
The following message may be displayed when the create
nPartition wizard is started.
There are no unassigned cells in the complex that can be the new
nPartition's core cell (i.e., there is no free cell that is attached to an
I/O chassis that contains core I/O). Every nPartition must have at least
one viable core cell. The Create nPartition task will exit.
|
Every nPartition needs a core cell. If there are no
available cells that meet the requirements to be a core cell, then a new
nPartition cannot be created. The wizard will be canceled when you click
the [OK] button.
Before you can create a new nPartition, you must have at least one free
viable core cell. Either delete an existing nPartition, or unassign a viable
core cell from an existing nPartition.
On servers based on the HP sx2000 chipset, core I/O is provided on each cell, so every cell is a
viable core cell. On all other nPartition servers, a cell is a viable
core cell only if it is attached to an I/O chassis
with core I/O.
