Configuring a cluster

You must add all the application servers that you joined into a cluster to the individual cluster lists of the servers. Using this list, the servers can recognize each other. You can configure these lists on each individual application server.

Before you begin

Define the application server as a member of the cluster. See Adding additional application servers.

Procedure

On the Administration menu, click Messaging > Server Settings (Application) > Cluster.
In the Number of member appliances in the cluster field, enter the number of application servers in the cluster.
The maximum number you can enter is 4.

The number of Member fields in the IP address of each appliance area increase to match the number you entered.
In each Member field, enter the IP address of an application server in the cluster.
- For a new cluster member, add each of the other cluster members to the cluster list to which the cluster belongs.
- For each preexisting cluster member, add the new member to the cluster list to which the cluster belongs.
Do not change the information in the Disk usage quota field.
Click Apply.
The system displays a confirmation message.
Click OK to proceed.
Repeat these steps until you configure all the application servers for your sites.
