Disaster Recovery Guide

Recovering a NetWorker Storage Node

The storage node allows you to access the volumes on which the backups for

all of the network computers reside. If the storage node experiences a disaster,

it must be recovered before you can restore application and user data to other

computers on the network.

The following sections provide information on recovering a NetWorker

storage node:

• “Prerequisites” on page 40

• “How to Recover a NetWorker Storage Node” on page 40

Prerequisites

Before recovering the NetWorker storage node, ensure that the UNIX

operating system is installed on the computer and that the NetWorker server

is functional and available on the network.

If you need to reinstall the UNIX operating system, see “Installing and

Configuring the UNIX Operating System” on page 28.

If you need to recover the NetWorker server, see “Recovering a NetWorker

Server” on page 32.

Additionally, ensure that you have the following:

• Hostname of the NetWorker server.

• Version and patch level of the NetWorker storage node software that was

on the computer before the disaster occurred.

• Name of any links to NetWorker directories. An example of a typical link

from a NetWorker directory to a user directory is /nsr to /usr/nsr.
