Situation Description

LPAR is being soft-capped

 

Possible Causes
  1. Over the last 4 hours the average physical standard CP resource consumed by the LPAR has exceeded its Defined MSU Capacity (WLM Soft Cap) or its entitled limit based on guaranteed physical standard CP resources.
  2. Additionally, this situation is true if the LPAR is a member of an LPAR Group and it is being soft-capped by the LPAR Group 4-Hour MSU Limit being exceeded.

 

Suggested Actions

If a WLM soft-cap is defined for the LPAR, consider re-evaluating this limit based on the service goals of the workload(s) running on the LPAR

Check LPAR weights are established such that the LPAR is getting a sufficient share of the CPC's physical CPU resources. This applies if the CPC physical CPU resources are not fully utilized at the time of the high utilization and the entitled physical standard CP resource available to the LPAR is insufficient to meet workload demands.

In the case of capping due to the LPAR Group 4-Hour Rolling Average MSU Limit being exceeded the consumption of CPU resources across all the LPAR Group members requires evaluation.
