38CHAPTER 5: UPGRADING A BRIDGE/ROUTER USING THE COMMAND-LINE UTILITIES

To check which version you have installed, enter:

bcmdiagnose -h

The version of the installed utilities is displayed in the following message:

bcmdiagnose version 11.3. Copyright 3Com Corporation 1999

If the version of the utilities you have installed is not version 11.3, you must first install the 11.3 utilities according to Chapter 2.

4Install the software. From a CD-ROM:

For UNIX, enter:

bcminstall

The path option may be used to install the utilities on an NMS that has two or more CD-ROM drives or to install from a remote CD-ROM drive. You must explicitly specify the second or remote CD-ROM drive using:

bcminstall -cdrom [<path>]

For example, to install software from a second CD-ROM drive on a Solaris machine, enter:

bcminstall -cdrom /cdrom/cdrom1/image

After the installation is complete, the screen shows an inventory of all bridge/router packages installed, including previous versions you have installed.

For Windows, open a command window and use:

bcminstall -cdrom <CD-ROM drive>:\image

From a Tarred File, use:

bcminstall -tar <path>/<filename>

From an Image File, use:

bcminstall -image <path>/<filename>

The image file is the NETBuilder bridge/routers boot file, for example, boot.29K or boot.68k.

Software Directories The bcminstall utility installs the software on the NMS in the following directory:

Windows:

\%tftpboot%\image\<platform>\SWFW\<version>\<pkg>

UNIX:

/tftpboot/image/<platform>/SWFW/<version>/<pkg>

For UNIX, if there is not enough space on the disk, you can link /tftpboot to another disk. For example, to link /tftpboot to the usr directory enter:

ln -s /usr/tftpboot /tftpboot

The utilities work only with the default directory names and structures.
