Description of problem:
On the PowerVM based OCP cluster, with the SMT change from 8 to 4, while the worker node has actual 12% CPU utilization , the OCP admin tool reports 92% CPU utilization.
Version-Release number of selected component (if applicable):
OCP 4.11.9
How reproducible:
The IBM Cloud Pak for Data 4.5.x documentation recommends to change SMT level using the Machine Configuration modification. https://www.ibm.com/docs/en/cloud-paks/cp-data/4.5.x?topic=settings-changing-power Before following the steps in the above link , first on the PowerVM based OCP cluster run the following command oc adm top nodes Then observe the CPU utilization of the worker nodes, then follow the steps above and after SMT has been changed and validated, re-run the same command as above to note the CPU utilization. Follow the steps in the above link and once the cluster SMT level has been
