Managing high availability

After you have configure an PowerHA® solution, you can manage that solution by using interfaces that are related to high availability.

Managing clusters
Using PowerHA, 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.
Managing independent disk pools
In a high-availability environment, it is necessary that the application and its data remain consistent among the nodes that participate in high availability. An independent disk pool, also called an independent auxiliary storage pool (IASP), is a disk pool that contains objects, the directories, or libraries that contain the objects, and other object attributes such as authorization and ownership attributes. An independent disk pool can be used to help in this situation. Ownership of data and applications that are stored in an independent disk pool can be switched to other systems that are defined in the device CRG. PowerHA technology provides high availability during planned and some unplanned outages.
