Console-Access Devices

You must have console access to all cluster nodes. If you install Cluster Control Panel software on your administrative console, you must provide the hostname of the console-access device used to communicate with the cluster nodes. A terminal concentrator can be used to communicate between the administrative console and the cluster node consoles. A Sun Enterprise 10000 server uses a System Service Processor (SSP) instead of a terminal concentrator. A Sun Fire^TM server uses a system controller. For more information about console access, see the Sun Cluster 3.1 Concepts Guide.
