    OCP 4.18.22

    not 100% reproducible

    1.restart OCP masters one by one (waiting for the cluster getting back in an healthy state between each task)
    2.verify for performanceprofiles getting into degraded state
    
    

    Performanceprofile might get into degraded state and the only way to fix it is by restarting the pod

> How did you reboot the hosts?

Node restart is done through redfish with curl command.

> Did you wait for each master node being up and the cluster healthy again before moving to the next one?

Yes. Case is monitoring master node status first through ping and redfish and when node is up and running, through oc command: "oc get nodes". Only after previously restarted master is visible in node configuration, second one is restarted.
