Returns a list of failover clustered instance nodes on which an instance of SQL Server can run. This information is useful in failover clustering environments.
This Microsoft SQL Server 2000 system function is included for backward compatibility. We recommend that you use sys.dm_os_cluster_nodes (Transact-SQL) instead.
The following example uses fn_virtualservernodes to query on a clustered server instance:
SELECT * FROM fn_virtualservernodes()
Here is the result set.
