How to Install and Configure the UNIX Operating System
When recovering a UNIX operation system, you must reinstall the same
version of UNIX and any patches that were in use prior to the disaster. Then
configure only those features that enable the computer to communicate over
the network. You can recover the remaining operating system configuration
settings after reinstalling the NetWorker software.
You can recover the UNIX operating system back to the original computer or
to a different computer.
To recover the operating system, complete the following tasks:
• “Task 1: Install the Operating System” on page 30
• “Task 2: Configure the Operating System” on page 30
• “Task 3: Configure the Devices and Test the Operating System” on
page 31
Important: Do not install the operating system from a UNIX X-Windows
session. Instead, recover the operating system in single-user mode from the
system console.
