Moving an Existing Linux
GroupWise 7 System into a
Heartbeat Cluster
If you are adding the high availability benefits of Heartbeat to a Linux GroupWise
®
7 system that is
already up and running, the first step is to install Heartbeat, as described in Chapter 29,
“Introduction to GroupWise 7 and Heartbeat on Linux,” on page 281 .
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 do not 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 storage partitions in your cluster you want to use for GroupWise domains
and post offices.
‰ Determine the nodes in the cluster where you want GroupWise agents to fail over.
If any nodes in your cluster are servers where GroupWise agents have been running in the past
and have been starting automatically, use the following command to make sure that they do not
start automatically in the future:
chkconfig grpwise off
In a cluster, the GroupWise agents should not start automatically when a node restarts.
‰ Review Chapter 30, “Planning GroupWise in a Heartbeat Cluster,” on page 285 and
Chapter 31, “Setting Up a Heartbeat Cluster,” on page 297 . Fill out the “Heartbeat Clustering
Worksheet” on page 293 and the “System Clustering Worksheet” on page 140 to help you
decide which domains and post offices you want move to which shared storage partitions.
‰
Move a domain and/or post office onto the shared storage partition, following the instructions
in “
Moving a Domain ” in “ Domains ” or “ Moving a Post Office ” in “ Post Offices ” in the
GroupWise 7 Administration Guide .
‰
Using the information on the “System Clustering Worksheet” on page 140 , install the agents as
needed for the first clustered domain and/or post office, following the instructions in
Section 14.4, “Installing and Configuring the MTA and the POA in a Cluster,” on page 146 .
‰
Test the first component of your clustered GroupWise system, following the instructions in
Section 14.5, “Testing Your Clustered GroupWise System,” on page 160 .
‰ Take care of the cluster management details described in Section 14.6, “Managing Your
Clustered GroupWise System,” on page 161 .
