How to setup a Failover sql server in SharePoint 2013

Question

Hi All,

 

We have a primary SQL server and another sql server for Failover. In central administration, when i click on the WSS_Content database that will take me to the next screen- where i can see its details and including Failover database server text box field.

 

Here we can enter the Failover server machine name. Is it enough or do we need to configure the server by executing any Powershell commands or anything else.Kinldy reply.

 

-Thanks
