CLI Overview

The Command Line Interpreter (CLI) is one of the user interfaces through which you control your StorageWorks array controller in the StorageWorks subsystem. The CLI commands allow you to manage the subsystem by viewing and modifying the configuration of the controller and the devices attached to them. You can also use the CLI to start controller diagnostic and utility programs.

While the CLI provides the most detailed level of subsystem control, a graphical user interface (GUI) is available for use with the CLI. The GUI, StorageWorks Command Console (SWCC), replicates most of the functions available within the CLI in graphic form and provides a user-friendly method of executing CLI commands.

CLI commands for configuring and viewing the controllers use the relative terms “this controller” and “other controller.” See “Typographical Conventions,” page xviii, for an explanation of these terms.

Using the CLI

You can access the CLI by connecting a maintenance terminal to the maintenance port on the front of the controller. See “Establishing a Local Connection to the Controller,” page 2–26for instructions explaining how to connect a local terminal to the controller. After you have initially configured the controller, making it visible to the host, you can perform all other configuration tasks through a remote connection.

The section entitled “Maintenance Port Precautions,” page xvii, explains precautions you should observe when operating the CLI through a maintenance port.

Command Overview

The CLI consists of six basic command types:

■Controller Commands—Configure the controller’s SCSI ID numbers, maintenance terminal characteristics, CLI prompt, and so forth. Controller commands are also used to shut down and restart the controller.
