Feature Overview

In 4.18 we introduced the automated recovery of the control plane nodes, where when the cluster loses quorum due to control plane nodes failure recovering it is done running a recovery script and quorum is restored almost immediately, before we bring back the nodes that failed:

https://docs.redhat.com/en/documentation/openshift_container_platform/4.18/html/backup_and_restore/control-plane-backup-and-restore#dr-quorum-restoration 

This process replaces a series os manual steps that aren't needed after the added automation. The manual steps are still documented:

https://docs.redhat.com/en/documentation/openshift_container_platform/4.17/html/backup_and_restore/control-plane-backup-and-restore#dr-restoring-cluster-state 

This document has 24 sections with a total of 75 steps, which is more prone to human error than the new procedure.

Goals 

• Validate that the manual process doesn't cover any use case that the automated process doesn't cover.
• Remove the manual process once confirmed we don't need it and it can be entirely replaced by the new method.
