Feature Description

SMF supports the maintenance mode flag to disable the impact on a cluster if the cluster in GR setup is scheduled for in-service (rolling upgrade). This is useful so that the other mated cluster executes its responsibility and other activities on the targeted cluster without any issue.

If the maintenance mode flag is set to true, cluster role change and GR trigger for the rack is allowed only in case of CLI-based failover.

For more information, refer to the Redundancy Support chapter.
