Legato NetWorker ClientPak and Storage Node Installation Guide

Configuring and Operating NetWorker Autochanger Support

This section provides information on how to configure and operate NetWorker

autochanger support. Much of the information is copied from the Legato NetWorker

Administrator’s Guide, UNIX Version. The commands have been modified to use the

MPE program names. Refer to the chapter on Device and Media Management in the

Legato NetWorker Administrator’s Guide for your NetWorker server platform for

additional information pertinent to all backup devices. The following topics are

addressed in this section:

• “Testing the Autochanger Connection” on page 37

• “Autochanger Configuration and Management” on page 41

• “Volume Management” on page 45

Overview

The NetWorker software displays the term “jukebox” to refer to an autochanger. The

term “autochanger” refers to a variety of robotic libraries, including carousel, library,

near-line storage, datawheel, and autoloader.

Autochangers automate the task of loading, mounting, and labeling backup media.

Before NetWorker can back up data to an autochanger, you must:

• Connect and configure the autochanger to the NetWorker storage node machine.

• Install and enable the NetWorker storage node software and device drivers.

• Use the JBCONFIG program to configure your autochanger.

• Enable the NetWorker Autochanger Module.

• Load and label your volumes.

You determine most of the autochanger configuration when you run the JBCONFIG

program. After you complete the configuration tasks, you can change the attributes of

the autochanger in the Jukeboxes resource.

Important: You cannot add or create autochanger resources using the NetWorker

Administrator program. You can only modify autochangers previously installed and

configured using the JBCONFIG program.

If you want to install and use additional autochangers for backups with your

NetWorker storage node machine at a later time, you must purchase and enter

additional enabler codes to allow NetWorker to use the additional autochangers.

You use the NetWorker Administrator program (NSRADMIN or JBCONFIG) to

modify the configuration of an autochanger or an autochanger device, and remove an

autochanger from the list available for use by NetWorker.

The nsrd daemon must be running on your NetWorker server before you start the

JBCONFIG program.
