If you are adding the high availability benefits of OES Cluster Services to a GroupWise system that is already up and running, the first step is to install OES Cluster Services, following the instructions in OES Cluster Services for Linux Administration Guide for your version of OES Linux. You should also review Introduction to GroupWise and OES Cluster Services on Linux to help you apply clustering principles and practices to your GroupWise system.
You do not need to transfer your entire GroupWise system into the cluster all at once. You can transfer individual post offices where the needs for high availability are greatest. You can transfer a domain and all of its post offices at the same time. You might decide that you don’t need to have all of your GroupWise system running in the cluster.
This section provides a checklist to help you get started with moving your GroupWise system into a clustering environment:
Decide which shared partitions in your cluster you want to use for GroupWise domains and post offices.
Decide which nodes in your storage area network you want have on failover lists for the GroupWise agents.
Review Planning GroupWise in a Linux Cluster. Fill out the System Clustering Worksheet to help you decide which domains and post offices you want move to which shared partitions.
Move a domain and/or post office onto the GroupWise partition, following the instructions in Moving Your Primary Domain to Another Server
in the GroupWise Administration Guide.
Review Configuring the Linux Agents in a Cluster, fill out the Agent Clustering Worksheet, and install the agents as needed for the first clustered domain and/or post office, following the instructions in Creating a New GroupWise System to Work with OES Cluster Services. This includes setting up the load and unload scripts for the GroupWise partition.
Test the first component of your clustered GroupWise system, following the instructions in Introduction to GroupWise and OES Cluster Services on Linux.
Take care of the cluster management details described in Managing Your Clustered GroupWise System on Linux.
Move more domains and post offices into the cluster as needed. If you have GroupWise libraries, see Planning a New Library for a Clustered Post Office.
Add other components to your clustered GroupWise system as needed, following the instructions in: Implementing the Internet Agent in a Linux Cluster.
