Support Failover Group
A failover group is a group that contains the resource that can be run at a single node at a time.
A failover group switches to the standby mode when the main resource is failed. The resource in this group only operates at the operating nodes.
For instance, a virtual IP address cannot be used at the operating node and the standby node at the same time. In addition, if a virtual IP address causes troubles, it will switch service to the standby node.
...
A single node group is a group of resources that can be run at a single node.
A single node group does not failover. When the included resource experiences troubles, a single node group will try to be online as many times as designated.
SingleNode Single Node Cluster
A single node cluster is a cluster of resources that can be run at a single node. A single node cluster does not failover.
A single node cluster only supports a single node group.
