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.

For information about how to disable validation on certain parameters in the task, see Turning off validation in a task.
Procedure
- Open the Server Automation domain.
- From the Domain Panel, select PowerVM Modify a Logical Partition (LPAR) Profile.. and select
- 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 for 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 for 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 for the parameter. For more information, see Turning off validation in a task.
- 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.
- 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.
- 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.
- Click Take Action, and in the Take Action dialog box, select the LPAR that you want to modify, and click OK.
