You can define dynamic cluster members when you are creating a dynamic cluster, or you can add dynamic cluster members to an existing dynamic cluster.
To access this administrative console page, click Servers > Dynamic clusters > New.
To add dynamic cluster members to an existing dynamic cluster, click Servers > Dynamic clusters > dynamic_cluster_name > Dynamic cluster members > Add. You can only add dynamic cluster members to dynamic clusters that are in manual membership mode and do not have a membership policy defined.
