CLUSTERS

What occurs when you remove a server from a cluster
When the removed server detects the change to its Domino Directory that indicates the server was removed from a cluster, the Cluster Administrator on that server does the following:
Note It is possible to remove a server from a cluster even if the server is shut down. However, the documents for this server's databases remain in the Cluster Database Directory. To remove these documents, open the Cluster Database Directory, select the Databases by Server view, and manually remove the documents for the server.

The role of the Administration Process in removing a server from a cluster

You can choose to remove a server from a cluster immediately or you can submit the request to the Administration Process. If you submit the request to the Administration Process, Domino creates a Remove Server from Cluster request to the Administration Requests database on the server from which you initiated the Remove from Cluster request. If you make the request on the administration server, the Administration Process acts immediately on the request. If you make the request from another server, that server's Administration Requests database must replicate with the administration server before the Administration Process can process your request. The Administration Process then removes the cluster information from the Server document in the administration server's Domino Directory. The next time the administrative server replicates with the removed server, Domino replicates these changes to the removed server's Domino Directory. Cluster membership changes do not take effect until the removed server receives the changes to the Server document.

If you choose to remove a server from a cluster immediately, Domino immediately makes the changes to the Server document on the server from which you initiated the Remove from Cluster command. If you initiate the request on the server you are removing, Domino updates the cluster information immediately on the server you're removing. You do not have to wait for the Administration Process to update the Domino Directories on the cluster servers. Although this removes the server from the cluster faster, it can also lead to replication conflicts.
