Windows Azure Pack, SQL Always On, Listener and Port story

Hi Guys,

Today, I was at a customer where my colleague and I have to install Windows Azure Pack. The DBA gave us the SQL Always On Listener name and we started the setup. We specified the SQL listener, the credentials, the passphrase…

…and it failed with the following error message: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible
The complete error message is available:

Error:

System.Data.SqlClient.SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server) —> System.ComponentModel.Win32Exception (0x80004005): The system cannot find the file specified

After digging for a few hours, we finally found the following post: http://www.sqlservercentral.com/Forums/Topic1376770-1549-1.aspx saying that the Listener name could not be enough for certain application and that we also need to specify the port. The format to use is the following LISTERNAME,PORT.

Let’s try that, we specified the our ListerName,Port as below:

And we’ve been able to complete our Windows Azure Pack installation J

Have a good week!

Cheers
