Launching Cluster Console Tools

All CCM tools are launched using the same command-line form:

% tool_name clsluster_name

where tool_name is cconsole, ctelnet, or crlogin, and cluster_name is a name given to the cluster at installation time. For example,

• Launch ctelnet by entering:

  % ctelnet hpc_cluster

• Launch crlogin by entering:

  % crlogin hpc_cluster

• Launch cconsole by entering:

  % cconsole hpc_cluster

If you want to use cconsole to monitor messages generated while rebooting the cluster nodes, you will need to launch it from a machine outside the cluster. If you launch if from a cluster node, it will be disabled when the node from which it is launched reboots.

Because cconsole accesses the console ports of every node in the cluster, no other accesses to any console in the cluster will be successful while the cconsole session is active.

Note that all three CCM commands take the standard X/Motif command-line arguments.
