Firmware Update Manual Page 1
Introduction
Compatibility
For information about any firmware release, see the readme.txt file that accompanies the firmware. Such
information includes compatibility, cautions and warnings, known issues and files included in the
release.
This manual does not contain the procedures themselves. It serves as a guide to the publication that
contains the procedures you need.
Prerequisites
• Local boot disk.
• The intended Fibre Channel target should be big enough to hold all system files and the swap
slice of the current local boot disk.
Things to Know Before You Download
• Firmware differs between adapter models. Make sure you download the appropriate firmware for
your adapter.
• Before you download the files, create a directory into which you can download and unzip them.
• As a measure of protection, ensure that critical files on your local boot disk are backed up.
• Depending on the release, the firmware kit contains either a .all file or a .awc file that updates
the kernel if the existing kernel is an earlier version. If the update process is interrupted (such as
by a power outage) and the kernel is being updated, you may have to return the adapter to
Emulex for repair.
• Firmware may be bundled with or without boot code. Boot code allows you to designate a Fibre
Channel drive as the boot drive. If the adapter’s devices will be used to boot the system, Emulex
recommends that you use the firmware package that includes boot code, if one is provided. If
you select a firmware image that includes boot code, the update procedure will load both the
new firmware and boot code at the same time. After updating, refer to the boot code manual for
procedures on enabling the boot code on your adapter.
• If you are currently using an Emulex driver, you can update firmware with the management
application that was loaded when the driver was installed.
