Dropping a cluster allows a user to undo all the steps he or she performed to create a cluster. Dropping a cluster is different from removing a cluster from a server group. You can only drop clusters that are shut down.
You remove a cluster completely when you drop it. It
is no longer available for restart.
To drop the cluster:
Right-click the name of the cluster you want to drop.
Select Drop Cluster from the list.
Enter the login for the managing agent (usually, uafadmin).
Select OK.
