If you are adding the high availability benefits of a Windows cluster to a GroupWise 2012 system that is already up and running, the first step is to set up the cluster and review Section 20.0, Introduction to GroupWise 2012 and Clustering on Windows 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 Microsoft cluster:
Decide which shared disks you will use for GroupWise administration (ConsoleOne and the software distribution directory).
Decide which shared disks you will use for GroupWise domains and post offices.
Plan the resource groups for domains and post offices.
Review Section 21.0, Planning GroupWise in a Windows Cluster. Fill out the System Clustering Worksheet to help you decide which domains and post offices you will move to which shared disks.
Review Planning Cluster-Unique Port Numbers for Agents in the Cluster and fill out the Network Address Worksheet to record resource group IP addresses and to specify cluster-specific port numbers for all of your GroupWise agents.
Select the first shared disk that will be part of your clustered GroupWise system and set up the resource group for it, following the instructions in Creating GroupWise Resource Groups and Configuring Short Name Resolution.
Review Section 21.8, Deciding How to Install and Configure the Agents in a Windows 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 Section 22.5, Installing and Configuring the MTA and the POA in a Windows Cluster.
Test the first component of your clustered GroupWise system following the instructions in Section 22.6, Testing Your Clustered GroupWise System.
Take care of the cluster management details described in Section 22.7, Managing Your Clustered GroupWise System.
Move more domains and post offices into the cluster as needed. If you have GroupWise libraries, see Section 21.4, Planning a New Library for a Clustered Post Office.
Move GroupWise administration into the cluster as needed.
Add other components to your clustered GroupWise system as needed, as described in the following sections:
