6.4.1 Creating a New Cluster

1 In the Administration Console, click Access Manager > New Cluster.
2 Fill in the following fields:
Cluster Name: Specify a display name for the cluster.
Type: Select the type of cluster you want to create: Gateway Appliance or Gateway Service.
Primary Cluster Server: Select the server that is to be the primary server in the cluster. This
field is empty until you have selected one or more servers to be members of the cluster.
3 In the Server Name list, select the servers that you want to be members of the cluster.
You can create a cluster of one, and add additional servers later.You cannot create a cluster that
contains Access Gateway Appliances and Access Gateway Services. The cluster can contain
only one type of Access Gateway.
Each server you add to the cluster adds about 30 seconds to the time it takes to configure the
cluster because certificates must be synchronized and configuration options must be sent to that
server. If you create a very large cluster of twenty servers, it can take up to ten minutes to
configure and create the cluster.
4 Select the server you want to be the Primary Cluster Server.
5 Click OK.
6 After the cluster has been created, each server in the cluster needs be restarted. On the Access
Gateways page, click Update All by the name of the cluster.
