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 nPartitionCreate 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.

This action will be dimmed and unavailable if there are no free cells in the complex, or if any non-free cells are selected or in the scope of the current view.

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.

  1. » Set nPartition Name

    Specify the partition name of the new nPartition.

  2. » Select Cells

    Select the cells that will belong to the nPartition.

    Only free cells can be assigned to the new nPartition. If you want to use cells that are currently assigned to other nPartitions, you must first remove those cells from the nPartitions that they are assigned to, and then create the new nPartition out of the (now) free cells. See the unassign cell(s) help topic for information about removing cells from an nPartition.

  3. » Set Cell Attributes

    Set optional attributes of the cells in the nPartition.

  4. » Configure Memory

    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.

  5. » Set Boot Options

    Choose whether the nPartition will automatically boot to the system firmware user interface once it has been created, or will be booted manually later.

  6. » View Summary

    Review a summary of the nPartition's configuration, along with the results of a set of high availability checks.

  7. » Finish

    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.
