Setting up your GroupWise system using a server cluster is the preferred method for providing high availability access to your GroupWise clients by ensuring you have failover redundancy and load balancing of available server assets. GroupWise uses OES Cluster Services (NCS) for clustering.
Your cluster needs to be set up before you create a GroupWise system, so you can configure GroupWise administration and agents to use the cluster as you install GroupWise. Before you begin with the instructions contained in the sections below, review the content in Overview of OES Cluster Services
in the OES Cluster Services for Linux Administration Guide.
