2. Configuring the SQL Server Instance
Now that we have all three Windows servers in a
failover cluster, we need to enable the AlwaysOn Availability Groups
feature within each SQL Server instance. To do this, we connect to each
server: SQL-EAST, SQL-WEST, and SQL-SOUTH
and launch the SQL Server Configuration Manager found under the
Configuration Tools folder within Microsoft SQL Server 2012. When the
SQL Server Configuration Manager launches, click the SQL Server
Services node, then select the Properties context menu of the SQL
Server service account. Click the AlwaysOn High Availability tab, and
check the Enable AlwaysOn Availability Groups check box, as shown in Figure 4.

Restart the SQL Server service, and now, your SQL Server instance is ready for AlwaysOn Availability Groups.
