Assuming the cluster has already been configured, edit the cluster configuration file to update the
"MAX_CONFIGURED_PACKAGES" (for example, increase MAX_CONFIGURED_PACKAGES by
the number of packages you are adding to the cluster). After editing the configuration file apply
the change via the cmapplyconf -C <cluster_config_file> command.
Distribute the cluster configuration file to all the nodes of the cluster using rcp (this is optional but
recommended).
The cluster has been updated so that you can add packages. To actually bring the cluster up, issue
the command cmruncl, then cmviewcl to see the cluster up and running.
