Creating a Logical Partition (LPAR)

Using the PowerVM Create a logical partition (LPAR) task, you can create a new logical partition (LPAR) on a PowerVM® Managed System.

Before you begin

You must deploy and configure a management extender for PowerVM on an IBM® Endpoint Manager server. For more information, see Deploying a PowerVM Management Extender and Configuring a PowerVM management extender.

You must activate the following analyses:
  • PowerVM HMC Overview
  • PowerVM LPAR Overview
  • PowerVM Managed System Overview
  • PowerVM VIOS Overview
To activate the analyses, navigate to the Domain Panel of the Server Automation domain and select Virtualization > PowerVM > Setup and Maintenance and select PowerVM HMC Overview. In the Analysis: PowerVM HMC Overview pane, select Activate. Repeat this action for the PowerVM Managed System Overview, PowerVM LPAR Overview, and PowerVM VIOS Overview analyses.

For information about how to disable validation on certain parameters in the task, see Turning off validation in a task.

Procedure

  1. Open the Server Automation domain.
  2. From the navigation tree in the Server Automation domain, click Virtualization > PowerVM > Managed System Operations > Configuration Management and select PowerVM Create a logical partition (LPAR).
  3. In the Partition section, add the name, ID, and profile details of the new LPAR.
    HMC
    Select the hardware management console on which you want to create the LPAR.
    Managed System
    Select a PowerVM managed system on which you want to create the LPAR.
    Partition Name
    Enter a name for the new LPAR. Ensure that the name that you enter is unique on the Managed System that you select. To override the validation that is provided on the parameter, select OFF in the Validation column to the left of the parameter. For more information, see Turning off validation in a task.
    Note: In later actions, when a Fixlet or Task targets the computer that you create by name, unique names allow the IBM Endpoint Manager Platform to route actions to the correct computers. If the computer has the same name as another computer, host, or agent, this can cause targeting errors.
    Partition ID
    Enter an ID for the new LPAR. Ensure that the ID that you enter is unique on the Managed System that you select. To override the validation that is provided on the parameter, in the Validation column to the left of the parameter and select OFF. For more information, see Turning off validation in a task.
    Profile Name
    Enter a profile name for the new LPAR. To override the validation that is provided on the parameter, select OFF in the Validation column to the left of the parameter. For more information, see Turning off validation in a task.
  4. From the Processing Mode list, select whether you want to add shared or dedicated processors to the new LPAR. If you select shared, the managed system assigns partial processor units from the shared processor pool to the new LPAR. If you select dedicated, the managed system reserves entire physical processors that can be used only by the new LPAR.
  5. In the Processing Settings section, you can configure the processing settings for the new LPAR. From the Processing Mode list, if you select shared, the task displays the following parameters: Minimum Processing Units, Desired Processing Units, and Maximum Processing Units. If you select dedicated, the task removes these parameters. Use the Total Processors available field to view how many processors are available on the managed system that you selected.
    Minimum Processing Units
    Enter the minimum number of processing units that you want to use to create virtual processors for the new LPAR. Each processing unit is equivalent to the processing power of one processor. You can enter whole numbers or decimal numbers. For example, 2 or 2.5 processor units can be assigned to the partition.
    Desired Processing Units
    Enter the number of processing units that you want to use to create virtual processors for the new LPAR. Each processing unit is equivalent to the processing power of one processor. You can enter whole numbers or decimal numbers. For example, 2 or 2.5 processor units can be assigned to the partition.
    Maximum Processing Units
    Enter the maximum number of physical processors that you want to use to create virtual processors for the new LPAR. Each processing unit is equivalent to the processing power of one processor. You can enter whole numbers or decimal numbers. For example, 2 or 2.5 processor units can be assigned to the partition.
    Minimum Processing Units required
    View the minimum processing units to ensure that you enter valid values in the Minimum Processors field.
    Minimum Processors
    Enter the minimum number of processors that you want to assign to the new LPAR. Enter a value that is greater than the minimum processing units. If you select Shared, these processors are virtual. If you select Dedicated, these processors are physical.
    Desired Processors
    Enter the number of virtual processors that you want to assign to the new LPAR. If you select Shared, these processors are virtual. If you select Dedicated, these processors are physical.

Results

In the Action: PowerVM Create a logical partition (LPAR) window, you can view the progress of the action. When the Status changes to Complete, the new LPAR is created. In the Computers list in the All Content domain, you can view the new LPAR. You can distinguish an LPAR from other computers by using the Device Type column in the Computers list. The Device Type of the new LPAR is PowerVM LPAR.

What to do next

To work with the new LPAR, you must create a client for the LPAR on a NIM server and then netboot the LPAR. For more information, see Creating a NIM client for an LPAR on a NIM server and Netbooting a logical partition.
