Shared Volume
For convenience throughout the rest of this section, the term "Messenger volume" means "a cluster-
enabled shared volume where the Messenger agents are installed." Complete the following planning
tasks for the Massager volume:

Selecting the Messenger Volume
If you are not planning to enable archiving, or if you are not anticipating a large Messenger archive,
you can use one Messenger volume. If you anticipate archiving a large number of messages so that
the Messenger archive grows very large, you might want to have a separate Messenger volume for
the Archive Agent and the archive database. The steps in this section cover setting up the Messenger
agents on a single Messenger volume.

Determining an Appropriate Failover Path for the Messenger Volume
By default, a Messenger volume is configured to have all nodes in the cluster in its failover path,
organized in ascending alphanumeric order. Only one node at a time can have the Messenger volume
mounted and active. If a Messenger volume's preferred node fails, the volume fails over to the next
node in the failover path.

Messenger volume fails over to.
Selecting IP Address Resolution Methods for the Messenger Volume
Because you are using a cluster-enabled volume for the Messenger agents, you must ensure that
short name resolution is always successful. For background information, see
