LPAR Cluster Section
The CPU Utilization Report provides an LPAR Cluster Section if at least one LPAR cluster is defined on the central processor complex (CPC).
An LPAR cluster is a set of logical partitions that are resident on the same CPC and in the same parallel sysplex.
Workload Manager (WLM) manages processor access based on workload goals by dynamically adjusting the weights of the partitions within an LPAR cluster and optimizing the number of online processors for each partition.
The LPAR Cluster section contains CPU utilization and the partition attributes that are managed by Workload Manager (weight and number of online processors), and it summarizes data at the LPAR cluster level.
An example of the LPAR Cluster Section of the CPU Utilization Report is shown in the following figure.

LPAR Cluster Section field descriptions
The table below describes each field in the LPAR Cluster Section of the CPU Utilization Report.
Field | Description | |
|---|---|---|
CLUSTER | name of the LPAR cluster | |
PARTITION | name of the partition | |
SYSTEM | MVS system name | |
WEIGHT - DEFINED | INIT | initial weight that the partition has when the system is IPLed The TOTAL line shows the weight of the LPAR cluster. |
MIN, MAX | minimum and maximum weight that the partition can have 1 | |
WEIGHT - ACTUAL | AVG | average weight of the partition |
%MIN | percentage of time that the actual weight was in the minimum bandwidth of minimum weight to minimum weight plus 10% 1 | |
%MAX | percentage of time that the actual weight was in the maximum bandwidth of maximum weight minus 10% to maximum weight 1 | |
PROCESSOR - NUMBER | DEFINED | maximum number of logical processors that can be online for the partition |
ACTUAL | average number of logical processors that were actually online for the partition | |
PROCESSOR - % BUSY | LOG | percentage of busy time over online time of logical processors |
PHY | percentage of busy time over online time of all physical processors The TOTAL line shows the CPU utilization of the LPAR cluster. | |
STORAGE (MB) - CENTRAL EXPANDED | central and expanded storage, in megabytes, assigned to the partition The TOTAL line shows the total storage for the LPAR cluster. | |
1 Three dashes (---) appear if the partition is not WLM-managed.
