Cluster zones

PowerHA® SystemMirror® Version 7.2.2, or later, supports the concepts of cluster zones. Cluster zones can be used to organize clusters in a variety of ways. For example, you might create a zone for all your production clusters, another zone for development clusters, and another zone for test clusters. You can also organize zones based on the geographical location of the clusters, such as clusters located in New York City and clusters located in Boston. Cluster zones can be organized by various application such as DB2 Clusters, WebSphere Clusters, or cluster zones can also be organized by customer name.

Zone management

A group of clusters form a zone. An administrator can create different zones and assign any number of clusters to a zone. However, one cluster cannot be member of multiple zones. By creating a zone, an administrator can restrict the user from accessing a specific group of clusters.

You can also provide access to users for specific zones. If you do not add a user to a zone, that user cannot view clusters that are associated with the zone.
Note: If a cluster is not assigned to any zone, it will be displayed as Unassigned Cluster and it will be accessible to all PowerHA SystemMirror GUI users.
