A logical cluster is assigned resources from the physical cluster:
Instances – are a logical cluster’s base instances, which means that they are started when a logical cluster starts and that a failback restores them.
Failover resources – are an ordered list of instances on which a logical cluster is to run should one or more of the base instances fail. Any instance in the physical cluster can be a failover resource. Workload management capabilities let you group and configure resources to specify failover order and precedence.
