If you are adding the high availability benefits of Novell® Cluster Services™ to a GroupWise® 7 system that is already up and running, the first step is to install Novell Cluster Services following the instructions in the clustering documentation for your version of NetWare®, as listed in Section 1.0, Introduction to GroupWise 7 and Novell Cluster Services on NetWare. You should also review Section 1.0, Introduction to GroupWise 7 and Novell Cluster Services on NetWare 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 could transfer individual post offices where the needs for high availability are greatest. You could 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 volumes in your shared disk system you will use for GroupWise administration (ConsoleOne® and the software distribution directory).
Decide which shared volumes in your shared disk system you will use for GroupWise domains and post offices.
Decide which nodes in your storage area network you will have on failover paths for the GroupWise agents.
Review Section 2.0, Planning GroupWise in a NetWare Cluster. Fill out the System Clustering Worksheet to help you decide which domains and post offices you will move to which shared volumes.
Review Planning Secondary IP Addresses and Cluster-Unique Port Numbers for Agents in the Cluster and fill out the IP Address Worksheet to select secondary IP addresses for cluster-enabled volumes and to specify cluster-specific port numbers for all of your GroupWise agents.
Select the first shared volume that will be part of your clustered GroupWise system and cluster-enable it, following the instructions in Cluster-Enabling Shared Volumes for Use with GroupWise and Configuring Short Name Resolution.
Move a domain and/or post office onto the cluster-enabled volume, following the instructions in GroupWise 7 Administration Guide.
Review Section 2.8, Deciding How to Install and Configure the 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 Section 3.5, Installing and Configuring the MTA and the POA in a Cluster. This includes setting up the load and unload scripts for the cluster-enabled volume.
Test the first component of your clustered GroupWise system following the instructions in Section 3.6, Testing Your Clustered GroupWise System.
Take care of the cluster management details described in Section 3.7, Managing Your Clustered GroupWise System.
Move more domains and post offices into the cluster as needed. If you have GroupWise libraries, see Section 2.5, 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, following the instructions in:
