1 Using the CLI

Introduction

The Common CLI Command Set provides a method of communication with the StoreOnce appliance

which is intuitive, consistent, and easy to use. The command set is broad in scope so that once

learned, you can use it with the entire StoreOnce portfolio of products.

The commonality of the CLI command set means that some unsupported commands will be present

in the CLI inline help (commands that are not applicable your appliance or are accessible through

a different CLI command). Any unsupported commands that are executed will return the failure

message: Command Failed - This command is not supported on this system.

You control the StoreOnce appliance by entering a command sequence using a specific grammar

and syntax. The operation defined by the command sequence is executed, and any output associated

with the operation is displayed in text or XML output (depending on the configuration settings).

When the operation is complete, the command prompt is displayed and you can enter the next

command sequence.

Command sequences are grouped by function. For example, commands related the network

configuration are in one group. This makes it easy to determine the correct command sequence

for a given operation. See “Categorical List of Commands” (page 10) for details.

Authorization levels are set for each user account to control what commands a user can perform.

This enables users to perform appropriate operations but prevents them from executing actions for

which they are not qualified; see “Accessing the CLI” (page 6).

Accessing the CLI

The CLI software embedded in the appliance enables you to manage and monitor storage-system

operation. For single-node products, you can access the CLI from an SSH terminal using an SSH

client application (freely available on the internet). For multinode products, you can access the CLI

from an SSH terminal connected to the master node using an SSH client application (freely available

on the internet). The CLI is running on the management console:

ssh <username>@<appliance IP address>

The Common CLI instruction set supports different authorization levels that permit execution of

different subsets of commands. Each authorization level has a unique command prompt. The

accounts in Table 1 (page 6) are created at the time of the StoreOnce system installation, and

the Administrator can create additional users at any time.
