Managing The Servers In The Cluster - Novell ACCESS MANAGER 3.1 SP2 - ACCESS GATEWAY GUIDE 2010 Manual

6.4.2 Managing the Servers in the Cluster

To view the servers that are currently members of clusters:
1 In the Administration Console, 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.
2 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.
3 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.
