+When you update a cluster that contains {op-system-base-full} compute machines, those machines temporarily become unavailable during the update process. You must run the upgrade playbook against each {op-system-base} machine as it enters the `NotReady` state for the cluster to finish updating. For more information, see "Updating a cluster that includes RHEL compute machines" in the additional resources section.
