hi folks, We have 2 node windows failover cluster with 2 node sql server failover cluster instance. We have added 2 more windows node to this WINDOWS cluster with the aim of adding these 2 nodes as a standalone sql instances and then configuring always on, on these 2 new nodes and then make all 4 sql instances part of always on group (2 old SQL FCIs and 2 new standalone). IS this possible? When i try to install standalone sql instance on node 3 and node 4 i get below error after rule check happens in the setup process and i can not proceed with the install.

Rule 'StandaloneInstall_HasClusteredOrPreparedInstanceCheck' detection result: HasFailedPreparedFeature = False, : HasClusteredFeature = True (12) 2023-04-05 17:03:49 Slp: Evaluating rule : StandaloneInstall_HasClusteredOrPreparedInstanceCheck (12) 2023-04-05 17:03:49 Slp: Rule running on machine: MAchine_01 (12) 2023-04-05 17:03:49 Slp: Rule evaluation done : Failed (12) 2023-04-05 17:03:49 Slp: Rule evaluation message: The instance selected for installation is already installed and clustered on computer MAchine_01.

    Hi @Heisenberg,

    The instance selected for installation is already installed and clustered on computer MAchine_01. To continue, select a different instance to cluster.

    It looks like this is not a newly installed instance for you. Do you have a cluster instance installed on node 3 and node 4? You can refer to my steps below when you install the new instance.

    Of course, if there are no other instances on your node you can choose to install the default instance.

    One more thing to note is that if your ultimate goal is to install a four-node cluster, you'd better configure a voting mechanism.

    Please refer to this link: WSFC Quorum Modes and Voting Configuration (SQL Server)

    Best regards,

    Seeya
