Modifying an LPAR Profile

Using the PowerVM Modify a Logical Partition (LPAR) Profile task, you can modify the profile name, the processing settings, and the memory settings of a logical partition (LPAR) profile.

Before you begin

You must activate the following analysis:
  • PowerVM® HMC Overview
  • PowerVM LPAR Overview
  • PowerVM Managed System Overview
To activate the analysis, 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 and PowerVM LPAR 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 Domain Panel, select Virtualization > PowerVM > LPAR Operations > Configuration Management and select PowerVM Modify a Logical Partition (LPAR) Profile..
  3. In the Partition section, select the LPAR that you want to modify and enter any changes to the following parameters:
    HMC
    Select the Hardware Management Console on which the LPAR that you want to modify is located.
    Managed System
    Select the PowerVM managed system on which the LPAR that you want to modify is located.
    Partition Name
    Select the name of the LPAR that you want to modify. Use the Partition ID field to verify that the LPAR that you select is correct. 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.
    Profile Name
    Select the LPAR Profile that you want to modify. 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.
    New Profile Name
    Enter a new name for the profile that you selected from the Profile Name list. 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. If you select shared, the managed system assigns partial processor units from the shared processor pool. If you select dedicated, the managed system reserves entire physical processors that can be used only by the selected LPAR profile.
  5. In the Processing Settings section, you can modify the processing settings of the selected LPAR. If you select shared, the task displays the following extra parameters: Minimum Processing Units, Desired Processing Units, and Maximum Processing Units. If you select dedicated, the task hides these three 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 physical processors that you want to use to create virtual processors. 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 physical processors that you want to use to create virtual processors. 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. 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 LPAR profile. Enter a value that is greater than the minimum processing units. If you selected Shared, these processors are virtual. If you selected Dedicated, these processors are physical.
    Desired Processors
    Enter the number of virtual processors that you want to assign to the LPAR profile. If you selected Shared, these processors are virtual. If you selected Dedicated, these processors are physical.
    Maximum Processors
    Enter the maximum number of virtual processors that you want to assign to the LPAR profile. If you selected Shared, these processors are virtual. If you selected Dedicated, these processors are physical.
  6. In the Memory Settings section, enter the changes that you want to make to the memory settings. Use the Installed Memory field Current Memory Available fields to determine how much memory is available to assign.
    Minimum Memory
    Select a minimum memory size for the selected LPAR.
    Desired Memory
    Select a memory size that you want to set for the selected LPAR.
    Maximum Memory
    Select a maximum memory size for the selected LPAR.
  7. Click Take Action, and in the Take Action dialog box, select the LPAR that you want to modify, and click OK.

Results

In the Action: PowerVM Modify a Logical Partition (LPAR) Profile window, you can view the progress of the action. When the Status changes to Complete, the LPAR profile is modified.
