 Use the following commands to install the SQL Server HA package and [!INCLUDE [ssnoversion-md](../includes/ssnoversion-md.md)] Agent, if they aren't installed already. If you install the HA package after installing [!INCLUDE [ssnoversion-md](../includes/ssnoversion-md.md)], you must restart [!INCLUDE [ssnoversion-md](../includes/ssnoversion-md.md)] for the change to take effect. These instructions assume that the repositories for the Microsoft packages are already set up, since [!INCLUDE [ssnoversion-md](../includes/ssnoversion-md.md)] should be installed at this point.
