 - **Cluster-wide shutdown**:
 
 ** **Planned**: A whole cluster is shut down and restarted with the same configuration, state, and data as before the restart. A planned shutdown includes rolling restarts, where the cluster is restarted member by member for scenarios such as installing an operating system patch or new hardware. xref:maintain-cluster:rolling-upgrades.adoc[Rolling upgrades] are an example of a rolling restart.
