# sys.fn_virtualservernodes (Transact-SQL)
[!INCLUDE[tsql-appliesto-ss2008-xxxx-xxxx-pdw-md](../../includes/tsql-appliesto-ss2008-xxxx-xxxx-pdw-md.md)]

  Returns a list of failover clustered instance nodes on which an instance of [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] can run. This information is useful in failover clustering environments.  
  
> [!IMPORTANT]
>  This [!INCLUDE[msCoName](../../includes/msconame-md.md)][!INCLUDE[ssSQL11](../../includes/sssql11-md.md)] system function is included for backward compatibility. We recommend that you use [sys.dm_os_cluster_nodes (Transact-SQL)](../../relational-databases/system-dynamic-management-views/sys-dm-os-cluster-nodes-transact-sql.md) instead.

## Syntax  
  
```  
  
fn_virtualservernodes()  
```  
  
## Tables Returned  
 If the current server is a clustered server, **fn_virtualservernodes** returns a list of failover clustered instance nodes on which this instance of [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] has been defined.  
  
 If the current server instance is not a clustered server, **fn_virtualservernodes** returns an empty rowset.  
  
## Permissions  
 The user must have VIEW SERVER STATE permission for the instance of [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)].  
  
## Examples  
 The following example uses `fn_virtualservernodes` to query on a clustered server instance:  
  
```  
SELECT * FROM fn_virtualservernodes();  
```
