Sun Cluster 3.0 12/01 System Administration Guide

1.2 Administration Tools

You can perform administrative tasks on Sun Cluster using a Graphical User Interface (GUI) or using the command line. This section provides an overview of these tools.

1.2.1 Graphical User Interface

Sun Cluster supports two Graphical User Interface (GUI) tools that you can use to perform various administrative tasks on your cluster. These GUI tools are SunPlex^TM Manager and Sun Management Center. See Chapter 9, Administering Sun Cluster With the Graphical User Interfaces for more information and for procedures about configuring SunPlex Manager and Sun Management Center. For specific information about how to use these tools, see the online help for each GUI.

1.2.2 Command Line Interface

You can perform most Sun Cluster administration tasks interactively through the scsetup(1M) utility. Whenever possible, administration procedures in this guide are described using scsetup.

You can administer the following items through the scsetup utility.

Quorum
Resource groups
Cluster interconnect
Device groups and volumes
Private hostnames
New nodes
Other cluster properties

Listed here are the other commands you use to administer Sun Cluster. See the man pages for more detailed information.
