Overview

A Veritas Cluster group is a collection of dependent or related resources that is managed as a single unit. Each Veritas Cluster group is linked to a designated node, which is responsible for activating the resources contained in the group. If a failure occurs in the designated node, the responsibility for activating the resources is switched over to a different node.

Veritas Clusters are composed of several clustered servers. Each server is responsible for running certain services and applications. The servers are used as backups for one another. When a system components fails, another server takes over to provide the necessary service.
