To view the servers that are members of clusters:
Click Devices > Access Gateways.
The members of a cluster are listed under the cluster name. The red double dagger symbol identifies the server that is the primary cluster server.
To add a server to a cluster, select the server, then click Actions > Assign to Cluster > [Name of Cluster].
A cluster cannot contain both Access Gateway Appliances and Access Gateway Services. The cluster can contain only one type of Access Gateway.
To remove a server from a cluster, select the server, then click Actions > Remove from Cluster.
Usually when you delete a server from a cluster, you have discovered that traffic is lighter than anticipated and that it can be handled with fewer machines while another cluster is experiencing higher traffic and can benefit from having another cluster member. When the server is removed, its configuration object maintains all the configuration settings from the cluster. When it is added to a new cluster, its configuration object is updated with the configuration settings of the new cluster. If your clusters are behind an L4 switch, you need to reconfigure the switch so that the server is assigned to the correct cluster.
When a server is removed from a cluster, its Embedded Service Provider is stopped. If you are not going to assign it to another cluster, you need to reconfigure the server so that it is protecting resources other than the ones it protected in the cluster. When you apply the changes by clicking Update, the Embedded Service Provider is restarted.
You cannot remove the primary cluster server unless it is the only server in the cluster. If you need to remove the primary cluster server from a multiple server cluster, you need to assign another the server to be the primary cluster server.
To modify which server is the primary cluster server, see Changing the Primary Cluster Server.
To view detailed information about a server in the group, click the name of the server.
To view detailed health information about a server, click the health icon of the server.
