CLI Command Introduction

Command Line Interface Reference Guide
CLI overview
Issuing CLI commands through the maintenance port of the controller is the most
direct means of communicating with the controller. 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, the
HP StorageWorks Command Console (SWCC) application is an alternative
application for using CLI commands. The HP SWCC replicates most of the
functions available within the CLI in graphic form and provides a user-friendly
method of executing CLI commands.
Using the CLI
Access the CLI through the following methods:
■ Connecting a personal computer (PC) or local terminal to the maintenance
port on the front of the controller.
■ Using the Diagnostic Utility Protocol (DUP) utility from a system terminal,
enable a remote connection to the controller. After the controller is initially
configured and made visible to the host, other configuration tasks can be
performed through this remote connection.
■ Using the SWCC by way of a PC setup on the subsystem. SWCC can be used
to perform most of the CLI commands that the local terminal can perform.
Command overview
CLI commands are divided into categories based on the options or structures they
control. The following subsections list these command categories.
Array controller commands
Array controller commands configure the maintenance terminal characteristics,
CLI prompt, and so forth. These commands are also used to shut down and restart
the controller. Controller commands consist of general and failover commands.
The CLI commands that pertain to the controllers in a general way are:
■ CLEAR_ERRORS CLI
■ CLEAR_ERRORS controller INVALID_CACHE
