Legato NetWorker ClientPak and Storage Node Installation Guide

Configuring the Storage Node on the NetWorker Server

This section describes how to configure NetWorker storage nodes for MPE/iX to use

autochangers and tape devices. These sections are adapted for MPE/iX from the Legato

NetWorker Administrator’s Guide, UNIX Version, for Release 5.1. For a detailed

description of storage nodes, refer to this document in the Documents Library from the

Legato home page (http://www.legato.com).

Storage Nodes

A storage node is connected to a NetWorker server and one or more devices used in a

NetWorker backup and archive process. Devices attached to storage nodes are called

remote devices because they are not physically attached to the controlling NetWorker

server. The storage node runs special NetWorker software that controls devices. The

data stored on media in remote devices is tracked in the media database and online

client file indexes on the controlling NetWorker server.

Storage nodes you add to your NetWorker configuration can increase the NetWorker

server’s performance, give you more flexibility in designing your network, and

centralize the control of data management activities to one or more NetWorker servers.

To create a storage node, you must install the storage node binaries from the

NetWorker software distribution on the storage node computer. You already installed

the storage node automatically when you installed the NetWorker for MPE/iX

software.

Configuring Autochangers

The term “autochanger” refers to a variety of backup devices: autoloader, carousel,

library, near-line storage, datawheel, tape devices, and jukebox. Note that NetWorker

for MPE/iX does not support silos. For an autochanger, you must manually add the

storage node’s hostname to the Administrator list on the NetWorker server before you

define the devices with the JBCONFIG program.

To configure a remote autochanger, follow these steps:

1. Verify that the storage node is included in the Administrator list in the Server

resource of the controlling server. It must have the form manager.sys@hostname,

where hostname is the hostname of the storage node.

2. Run the JBCONFIG program on the MPE/iX storage node computer to define

each device in the autochanger. Refer to the JBCONFIG or jbconfig man page for

the syntax and options for this program.

3. When the JBCONFIG program is complete, you can remove the storage node’s

hostname from the Administrator’s list.

– If you need to configure a new autochanger later, you must add the hostname

before you run the JBCONFIG program again.

– After you add the storage node’s hostname to the Administrator list, one

instance of NSRMMD starts on the storage node for each device that it

controls. Refer to the NSRMMD or nsrmmd man page for the syntax and

options for this program.
