Creating capacity configuration for Linux on z Systems (BigFix scenario)

Edit online

To properly calculate subcapacity values for products that are installed on Linux on z Systems, create capacity configuration for such computers. First, run a fixlet that creates a file with manually entered capacity values and places it on the target computer. Then, run regular software and capacity scans to discover the installed software and calculate its license metric utilization.

Before you begin

Note: Automatic capacity configuration is supported on Linux on z/KVM, on z/VM and on System z10 starting from model E64 (type 2097) mainframes with z/VM 6.3. Additionally, such systems must meet the following requirements:
  • Must support the Store Hypervisor Information (STHYI) instruction.
  • Global performance data control option must be set in HMC for LPARs.
  • The debugs file system must be mounted.
To confirm the STHYI feature is listed within the CPU model configuration, you can run the following command: 
virsh dumpxml <guestname>
The working setup is expected to have this lines present in the hardware scan results: 

<cpu mode='.../>
<feature name="sthyi" policy="require"/>

If the automatic capacity configuration is supported, you do not have to perform any manual actions to calculate the capacity values.

About this task

The Create Capacity Configuration for Linux on z Systems fixlet is relevant on all computers where manual configuration is required. It is not relevant on computers where automatic capacity configuration is supported. If the fixlet is not relevant, you do not have to perform any manual actions to calculate the capacity values.

Procedure

  1. Log in to the BigFix® console.
  2. In the navigation tree, click Sites > External Sites > IBM License Reporting (ILMT) > Fixlets and Tasks.
  3. Select Create Capacity Configuration for Linux on z Systems and specify the following values:
    • Machine Type
    • Processor Type
    • Shared Pool Capacity
    • System Active Processors
  4. To run the task, click Take Action.
  5. Select computers for which you want to create the capacity configuration, and click OK.
    The fixlet is relevant only on computers on which creating the manual configuration is required.

Results

You created capacity configuration that will be used to calculate subcapacity values. If you want to edit or delete the capacity configuration, use the Edit Capacity Configuration for Linux on z Systems or Delete Capacity Configuration for Linux on z Systems task.

What to do next

To discover software that installed on the computers and calculate its license metric utilization, schedule regular software and capacity scans. For more information, see: Initiating software scans (BigFix scenario), and Initiating the capacity scan on all computers (BigFix scenario).
