To manage SQL Server failover cluster Instances and Always ON availability groups, you will need a Windows server failover cluster (WSFC). Windows Server tool called failover Cluster manager is used to manage Windows Server failover cluster. Using the failover cluster manager, you can manage the cluster very easily and efficiently and can easily perform different tasks like configure quorum, add new nodes to the cluster, failover the cluster group/resources to another node, add new disks, and much more. But sometimes if you are facing issues with the failover cluster manager and you are unable to connect to the cluster using the failover cluster manager, you will need to manage the failover cluster using the command line.
