A cluster is stopped using the stop-cluster command. The following example stops the cluster named mycluster. The command prompts for the administrative passwords.
$ asadmin stop-cluster --host myhost --port 1234 --user admin mycluster
myhost is the administrative server host, 1234 is the administrative port, admin is the administrative username.
For the full syntax, type asadmin help stop-cluster. When a cluster is stopped, all the server instances in the cluster get stopped. A cluster without instances cannot be stopped.
