BACKING UP AND RESTORING

7 SOFTWARE

 

You should always back up your software and configuration files to a network

 

management station (NMS) in case your hardware or software fails. This chapter

 

describes how to back up and restore the software using Upgrade Link or the

 

command-line utilities.

 

 

Prerequisites

Confirm the following items:

 

■ You have installed the utilities according to Chapter 2.

 

■ You have set the path for the utilities (UNIX only). If you have not set the path,

 

complete the following step for your UNIX shell:

 

■ For a C-shell installation, add the contents of the following file to the .cshrc

 

file for each user you want to have access to the utilities, including root:

 

/usr/3Com/common/data/.login-bcm

 

Or you can enter the path after every logon:

 

source /usr/3Com/common/data/.login-bcm

 

■ For a Bourne shell installation, add the contents of the following file to the

 

.profile file for each user you want to have access to the utilities, including

 

root:

 

/usr/3Com/common/data/.profile-bcm

 

Or you can enter the path after every logon:

 

. /usr/3Com/common/data/.profile-bcm

 

■ For NETBuilder II with DPE — All boot sources (primary, secondary, and test) are

 

on drive A. The DPE module has flash memory drives A and B, but the

 

NETBuilder Upgrade Management Utilities only support drive A. Use the

 

bcmconfig utility or the SysconF command on the NETBuilder II user interface

 

to set up the boot sources if they are not on drive A.

 

■ All configuration files are in the same directory as the boot image.

 

■ You have booted your bridge/router from the primary boot source.

 

■ For Upgrade Link — You have a web browser installed with Java support, such

 

as Netscape Navigator 4.5 or Internet Explorer 4.x, and it is in your path (UNIX).
