• You could wait with the installation of SP untill you have added the node-installation of all three SQL instances. After the installation of all three SQL instances you can apply the SP (on the third node) to all three instances at once.

    1. add server to WFSC at OS level

    2. install first SQL instance on node with 'add node' installation

    3. install second SQL instance on node with 'add node' installation

    4. install third SQL instance on node with 'add node' installation

    5. install SP on third node and apply to all three instances
