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 that is used to communicate with the cluster nodes.

• A terminal concentrator is 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 instead of a terminal concentrator.

For more information about console access, see the Sun Cluster Concepts Guide for Solaris OS.
