Using the information in the Hardware Group Report

With the hardware group capping limit, which can be set in the logical partition controls of the Hardware Management Console (HMC), another restriction to an LPAR is added. This limit enforces an absolute capping for each type of processor defined to every partition in the hardware group. Even when an LPAR is not limited by its weight, its defined capacity, or a group capacity limit, it can be limited by this hardware group capping value. The minimum of the following limitations is applied to any partition:

Defined capacity
LPAR weights
Group capacity limit
Absolute physical hardware capping limit
Hardware group capping value

The Hardware Group Report displays the settings of the hardware groups and their partitions.

Table 1. Fields in the Hardware Group Report
Field Heading	Meaning
HW GROUP NAME	Name of the hardware group.
PARTITION	Name of the logical partition.
SYSTEM	Name of the z/OS system.
HW GROUP LIMIT	Absolute limit on partition usage of all processor types that are members of the same hardware group, in terms of numbers of CPUs. If the hardware group name or the limit changed during the reporting interval, an asterisk (`*`) is appended.
