If you have not already done so we highly recommend that you review the Supported Clustering section of this help file.
In the Active/Passive (AP) Cluster, two Cluster Nodes manage a single Exchange Virtual Server (EVS). When you license an AP Cluster, be aware of the following:
GOexchange® is ALWAYS licensed on a per-server basis.
NOTE: Most organizations running AP clusters only license the Active Node. If you desire the ability to run maintenance from the Active and the Passive node you must purchase a license for each node.
During licensing, you must select/choose the EVS Name that you want licensed to the "Cluster Node/Server."
Maintenance actions will only run on an EVS/Cluster Node that was designated during installation and licensing.
If the node that is the primary Preferred Owner is offline, it must be brought online and assume ownership of the EVS before the Maintenance Action is run.
In a basic Active/Active (AA) Cluster, two Cluster Nodes manage two EVSs. When you license an AA Cluster, be aware of the following:
GOexchange® is ALWAYS licensed on a per-server basis.
NOTE: If you want GOexchange® to maintain all the "Cluster Nodes" in an Active/Active Cluster you must license each "Cluster Node" and configure/manage them separately
During licensing, you must select/choose the EVS Name that you want licensed to the "Cluster Node/Server."
Maintenance actions will only run on an EVS/Cluster Node that was designated during installation and or licensing.
NOTE: GOexchange® can only Maintain One EVS. If multiple EVSs are attached to a Cluster Node, GOexchange® will only maintain the EVS that was designated during installation and licensing and will ignore all other EVSs.
