Firmware management in a FICON environment

You can use either the CLI or Brocade Network Advisor to upgrade or downgrade your Fabric OS. Go

to http://www.brocade.com and follow the link under the Services and Support tab for Drivers and

Downloads 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. The Brocade Network Advisor 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 and downgrade considerations

Concurrent upgrades are generally supported from one major release level to the next, for example,

v6.4.0 to v7.0.0. 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.
