5–2 CLI Commands
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 2–26 for 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.
