  • Hi Satish,

    Do you want to create AlwaysOn Availability Group in your scenario? If that is the case, when you create AlwaysOn Availability Group between standalone instances, you need to have at least 2 VMs because each availability replica of a given availability group must reside on a different node.

    However, when you create  
    AlwaysOn Availability Group for SQL Failover Cluster, you need to have at least 3 VMs. For more details about how to create AlwaysOn Availability Group between SQL Failover Cluster Instance and a standalone or a Failover Cluster Instance, please review this blog.

    In addition, please post the full error message when you configure AlwaysOn Availability Group.

    Thanks,
