15.1.3 Determining an Appropriate Failover List for the Internet
Agent
By default, a GroupWise partition
organized in ascending alphanumeric order. Only one node at a time can have a particular
GroupWise partition mounted and active. If a GroupWise partition's preferred node fails, the
partition fails over to the next node in the failover list. You should customize the failover list for
each GroupWise partition based on the
As with the MTA and the POA, you need to decide which nodes in the cluster are appropriate
locations for the Internet Agent partition
on all of the nodes where you want the Internet Agent to be able to fail over. For a review of failover
lists, see Section 13.6.2, "Determining Appropriate Failover Lists for the Agents," on page
which describes the issues in the context of planning MTA and POA installations.

15.1.4 Determining Cluster Resource Information for the
Internet Agent
A cluster resource is a shared
that can function successfully anywhere in the cluster. Cluster resources include the GroupWise
agents and the Messenger agents. When using the Configure GroupWise for Clustering option, the
GroupWise Installation program needs to know the mount point for the
the Internet Agent domain is located.

15.1.5 Preparing DNS for the Clustered Internet Agent

In order for the Internet Agent partition to be recognized on your network, DNS must have an MX
record that includes the hostname corresponding to the secondary IP address of the Internet Agent
partition. A DNS A record associates the secondary IP address with the hostname.

15.1.6 Preparing Your Firewall for the Clustered Internet Agent

The Internet Agent receives incoming messages on the secondary IP address of the Internet Agent
partition. Your firewall configuration must be modified to allow inbound TCP/IP traffic from the
Internet to the Internet Agent secondary IP address on the following standard ports:
