Failover clustering 2008R2

I tested the failover clustering for SQL 2008R2.

When I stop the SQL server services manully, the failover did not fail to another resource. At the Faiolover cluster manager, SQl server(MSSQLSERVER)  only show the status for offline. I think it should be move to another owner intead of just show as offline.

Hope to get some advise.

Thanks
