Changing the PVU per core value

Available from 9.2.3. The number of processor value units is assigned per processor core based on the information that is provided in the PVU table. It might happen that the value that is assigned to a processor in your environment is incorrect. In such case, manually change the PVU per core value to ensure that subcapacity licenses are properly calculated. When the problem that causes incorrect detection of the PVU value is solved, reset the PVU per core to the value that is specified in the PVU table.

Before you begin

An icon representing a user. You must have the Manage Hardware Inventory permission to perform this task.

The Manually Adjust the PVU per Core Value fixlet that was used in earlier versions of BigFix InventoryLicense Metric Tool is deprecated. The PVU per core value can now be changed on the Hardware Inventory panel. If you previously changed the PVU per core value on some computers by using the fixlet, run the deprecated fixlet on these computers to remove the adjustment. Do it to avoid a situation in which the PVU values changed by the fixlet overwrite the values that you specify on the Hardware Inventory panel.

About this task

To properly calculate PVU values for Linux on IBM Power Systems, set the PVU per core value to 70.

Procedure

  1. In the top navigation bar, click Reports > Hardware Inventory.
  2. Click the pencil in the PVU per Core column, and click Change PVU per Core.
    Note: The pencil is not available for computers with the No Scan Data status. Capacity data is not available for such computers, and thus it is not possible to determine whether the PVU per core value was properly assigned or requires changing.

    Changing the PVU per Core value.
  3. Provide the PVU value that you want to assign to the processor.
    It will be changed for the server that is listed in the Server ID column and all virtual machines that are hosted on that server.
    Important: Ensure that you provide a correct PVU per core value as it affects your PVU reports. In case of doubts, contact BigFix Support for guidance.
  4. Provide a justification for changing the PVU value, for example a support case number. The justification is listed on the Audit Trail report. Then, click Change.

Results

The changed PVU per core value is displayed on the Hardware Inventory report. To reflect the change on other reports, recalculate the data. Open the All IBM MetricsAll Metrics report, and click Recalculate.

What to do next

When the problem that causes incorrect detection of the PVU value is solved, reset the changed PVU per core value to the value that is provided in the PVU table. To do this, click the pencil in the PVU per Core column, and click Reset PVU per Core. Then, click Reset. The PVU per core value is reset on the server that is listed in the Server ID column and all virtual machines that are hosted on that server.
