Firmware management in a FICON environment
You can use either the CLI or DCFM to upgrade or downgrade your Fabric OS. Go to
http://www.brocade.com and follow the link “Brocade Connect Login” to access firmware
packages. Registered users can log in and follow the links for downloads. New users can easily
register and download release notes.
Firmware is downloaded in a .gz or .zip file. DCFM has intelligence built-in that unbundles the
necessary files, making it unnecessary to unbundle the package. With both Web Tools or the CLI, it
will be necessary to unzip or ungunzip the package first.
For more information on the firmware download process, refer to the Fabric OS Administrator’s
Guide.
Upgrade/Downgrade Considerations
Concurrent upgrades are generally supported from one major release level to the next, for example,
v6.2.x to v6.3.x. As a precaution, always read the appropriate section in the Brocade Fabric OS
Release Notes before upgrading or downgrading firmware.
NOTE
Firmware may need to be upgraded in multiple steps. Consult the Release Notes for details.
When downgrading firmware, turn off and disable all features not supported in the final release.
For more information on the firmware download process, refer to the Fabric OS Administrator’s
Guide.
