Test and restore firmware on switches

Power-on firmware checksum test
FIPS requires the checksums of the executables and libraries on the filesystem to be validated
before Fabric OS modules are launched. This is to make sure these files have not been changed
after they are installed.
When firmware RPM packages are installed during firmwareDownload, the MD5 checksums of the
firmware files are stored in the RPM database on the filesystem. The checksums go through all of
the files in the RPM database. Every file compares its current checksum with the checksum that is
in the RPM database. If they are different, the command displays an output message informing you
of the difference.
Because the validation may take up to a few minutes, it is not performed during a hot code load. It
is only performed after a cold reboot of the switch.
For more information on FIPS, see
Chapter 7, “Configuring Security Policies”
.
Test and restore firmware on switches
NOTE
This section does not apply to SAS or storage applications applied to the FA4-18 AP blade.
Typically, users downgrade firmware after briefly evaluating a newer (or older) version and then
restore the original version of the firmware. Testing a new version of firmware in this manner
ensures that you do not replace existing firmware because the evaluated version occupies only one
partition on the switch.
ATTENTION
When you evaluate new firmware, make sure you disabled all features that are not supported by the
original firmware before restoring to the original version.
Testing a different firmware version on a switch
1. Verify that the FTP, SFTP, or SSH server is running on the host server and that you have a user
ID on that server.
2. Obtain the firmware file from the Brocade website at
http://www.brocade.com
or switch
support provider and store the file on the FTP or SSH server.
3. Unpack the compressed files preserving directory structures.
The firmware is in the form of RPM packages with names defined in a
.plist
file, that contains
specific firmware information and the names of packages of the firmware to be downloaded.
4. Connect to the switch and log in using an account with admin permissions.
5. Enter the firmwareShow command to view the current firmware.
6. Enter the firmwareDownload -s command to update the firmware and respond to the prompts.
