In a NetWare cluster, you have the option of installing the GroupWise software on each node in the cluster or on a GroupWise volume along with a domain or post office, as described in Section 2.8.3, Deciding Where to Install the Agent Software. Before you run the GroupWise Installation program to install updated software, make sure you understand where in your cluster the GroupWise software is already installed.
If your existing GroupWise software is installed on each cluster node, it is very important to update all nodes on the failover path of each domain and post office at once, because each domain and post office should be serviced by only one version of the agent software. If you do not update all nodes on the failover path at once, there is the potential for a domain or post office to be serviced by a different version of the agent software during a failover situation. This can cause database problems.
If your existing GroupWise software is installed on a GroupWise volume along with a domain or post office, updating the agent software on the GroupWise volume needs to be done only once, because the agents fail over along with the domain or post office they service.
Keep in mind these cluster-specific details as you follow the instructions in Update
in the GroupWise 8 Installation Guide to update your GroupWise system in a NetWare cluster.
