Implementing high availability

For IBM® i environments, a task-based approach is used to implement high availability. The task-based approach allows you to design and build a customized high-availability solution for your business, using different interfaces for technologies that are related to high availability.

You are required to install the IBM PowerHA® SystemMirror® for i licensed program number (5770-HAS) on each system that is participating in high availability. The task-based approach uses the PowerHA graphical interface from which you can create and manage the cluster, cluster resource groups, cluster administrative domains, and independent ASPs. With the task-based approach, other interfaces, such as the CL commands, can also be used to manage the technologies within your solution.
