Overview Of The Afu - Adaptec RAID 2120S Software Reference Manual

Adaptec SCSI RAID Software Reference Guide
Your Adaptec RAID controller uses nonvolatile flash to store on-
board software, such as BIOS, microprocessor kernel, and monitor.
Whenever it becomes necessary to update any of those components
you can update your controller's flash components using the AFU.
AFU updates the controller's flash by reading flash image data from
a supplied user flash image (UFI) file and writing it to the controller's
flash components. A UFI file contains all of a controller's flash
images, as well as information about each image. It also includes
general controller information, such as controller type, to ensure
that AFU uses the correct UFI file when updating the controller's
flash.
The process of updating a controller's flash must be done carefully
to avoid rendering the controller inoperable. AFU is designed to be
easy to use with all the necessary safeguards to prevent a user from
accidentally damaging the controller's flash contents.

Overview of the AFU

The AFU performs the following primary functions:
■
Update—Updates all the flash components on a controller
with the flash image data from a UFI file.
■ Save—Reads the contents of a controller's flash components
and saves the data to a UFI file. This enables you to later
restore a controller's flash to its previous contents should the
need arise.
■ Verify—Reads the contents of a controller's flash components
and compares it to the contents of the specified flash image file.
■
Version—Displays version information about a controller's
flash components.
■ List—Lists all the supported controllers detected in your
system.
■
Reset—Resets one or more controllers in your system.
