Use the administration server when adding a server to a
cluster. The administration server does not have to be part of the
cluster.
Before you begin
To add a server to a cluster, you must have the following
access rights:
- Author access and Delete Documents rights and the ServerModifier
and ServerCreator roles in the Domino® Directory
- Author access with Create documents rights in the Administration
Requests database
About this task
If a server is part of a different cluster, you do not
have to remove the server from that cluster to add it to the new cluster.
The Cluster Administration Process removes the server from its original
cluster and then adds it to the new cluster.
Note: You
cannot use the Web Administrator to add a server to a cluster.
Procedure
- From the Domino Administrator,
make sure the administration server or another server is current.
- Click the Configuration tab.
- In the Task pane, expand Server,
and click All Server Documents.
- In the Results pane, select the server(s) you want to add
to the cluster.
- Click Add to Cluster.
- Choose the name of the cluster you want to add the server(s)
to, and then click OK.
- Choose Yes to add the server to
the cluster immediately, and then continue to the optional Step 9.
Or choose No to submit a request to the Administration
Process to add the server to the cluster, and then continue to the
optional Step 8.
- Optional: If you chose No in
Step 7 and you did not use the administration server to add the server
to the cluster, perform these tasks:
- Force replication between the server you used and the administration
server so that the administration server receives the requested changes
sooner.
- Force replication between the administration server and the cluster
servers so the cluster servers receive the changes sooner.
- Optional: If you chose Yes in
Step 7, the cluster information is added immediately to the Domino Directory on the server
you used to add the server to the cluster. If the server you used
is not part of the cluster, replicate the changes to one of the cluster
servers.
Results
When you add a server to a cluster, there can be a performance
impact because of the amount of replication that must take place initially.
Depending on the types of databases on the server and the number of
replicas you create, adding a server can affect CPU performance, Input/Output,
and network traffic. Therefore, it is a good idea to add only one
server at a time to a cluster, depending on the ability of the equipment
in the cluster. If you set up a private LAN for cluster traffic, adding
servers is less of a concern because it does not affect your primary
network.
