Managing clusters
Using the PowerHA® graphical interface, you can perform many tasks that are associated with the cluster technology that is the basis of your IBM® i high availability solution. These tasks help you manage and maintain your cluster.
Note: The PowerHA graphical interface allows you to perform these tasks from any node in the cluster.
