The Veritas Cluster Management Console is a high-availability cluster administration and management solution. It can be configured to locally manage a single cluster or to centrally manage multiple clusters.
These two modes of configuration and operation are called single-cluster and multi-cluster. The differences between the modes are significant. Multi-cluster mode offers greater capability on a larger scale. Both modes require different installation and configuration procedures. The following table summarizes some of the differences between single-cluster and multi-cluster mode.
The configurational differences between the modes mean that you cannot switch a single Cluster Management Console installation from one mode to the other. However, the modes can co-exist in the same multi-cluster environment, with single-cluster-mode installations on VCS cluster nodes, and multi-cluster-mode installations on management server hosts. Such a deployment can be desirable if different IT administrators in your enterprise have different scopes of responsibility.
See the Veritas Cluster Server Installation Guide for information about installing Cluster Management Console.
See the Veritas Cluster Server Centralized Management Guide for information about managing multiple clusters using Cluster Management Console.
This chapter describes how to use the Cluster Management Console in single-cluster mode.
