This variable is updated during cluster addition or cluster deletion.
NOTE : This variable should not be modified manually; it is the AdminP process that modifies it when you move a server in or out of a cluster, since it changes the Cluster Name field in the Server document in a Domino Directory.
Valid Values are :
1 = Enabled
0 = Disabled
This parameter indicates that the server is partitioned and/or clustered.
Refer to the Readme.txt for details on issues with installs to partitioned servers.
Example : SERVER_CLUSTER_ON=0
