You can use a dedicated machine, known as the administrative console, to administer the active cluster. Usually, you install and run administrative tool software, such as the Cluster Control Panel (CCP) and the Sun Cluster module for the Sun Management Center product (for use with SPARC based clusters only), on the administrative console. Using cconsole under the CCP enables you to connect to more than one host console at a time. For more information about to use the CCP, see the Chapter 1, Introduction to Administering Sun Cluster, in Sun Cluster System Administration Guide for Solaris OS.
The administrative console is not a cluster host. You use the administrative console for remote access to the cluster hosts, either over the public network, or optionally through a network-based terminal concentrator.
If your cluster consists of the Sun Enterprise E10000 platform, you must do the following:
Log in from the administrative console to the SSP.
Connect by using the netcon command.
Typically, you configure hosts without monitors. Then, you access the host's console through a telnet session from the administrative console. The administration console is connected to a terminal concentrator, and from the terminal concentrator to the host's serial port. In the case of a Sun Enterprise E1000 server, you connect from the System Service Processor. See Console Access Devices for more information.
Sun Cluster does not require a dedicated administrative console, but using one provides these benefits:
Enables centralized cluster management by grouping console and management tools on the same machine
Provides potentially quicker problem resolution by your hardware service provider
