3 Defining a cluster with HP Insight CMU

3.1 HP Insight CMU service status

Obtain the status of all HP Insight CMU service components with the following command on the management node:

#/etc/init.d/cmu status

HP Insight CMU must be properly configured before using the GUI. Ensure that the core and java services report configured.

3.2 Launching the HP Insight CMU GUI

The HP Insight CMU GUI can be used from any workstation connected through the network to the cluster management node. The HP Insight CMU GUI is composed of the following modules:

•A Java GUI running on the client Windows or Linux workstation•A server module on the management node to run tasks on compute nodes

IMPORTANT: If the server module is not running on the management node, the client module cannot perform any tasks.

TIP: To close an unwanted dialog window, use ESC.3.2.1 HP Insight CMU main window

If not already done, start the HP Insight CMU GUI on your workstation. Depending on your selected method of launching the GUI, the IP address of the management node might be requested. If your workstation has more than one network interface, then the correct network interface to use for communication with the management node might also be requested by the HP Insight CMU GUI.

The following figure represents the HP Insight CMU main window.Figure 4 HP Insight CMU main window
