sys.dm_os_cluster_nodes (Transact-SQL)
Returns one row for each node in the failover cluster instance configuration. If the current instance is a failover clustered instance, it returns a list of nodes on which this failover cluster instance (formerly "virtual server") has been defined. If the current server instance is not a failover clustered instance, it returns an empty rowset.
