6. Perform one of the following tasks to download firmware:
• If you are using an FTP server to download the firmware, skip to Downloading firmware from an FTP server on page 96.
• If you are using a USB device to download the firmware, skip to Downloading firmware from a USB device on page 96. If
the firmware on the standby CP blade is more than one level down from the level on the active CP blade, you must have
formatted USB devices for each of the versions you will need to upgrade.
For details on supported upgrade paths and steps to upgrade through multiple versions of Fabric OS, refer to the Fabric OS
Release Notes , and the Fabric OS Upgrade Guide .
Downloading firmware from an FTP server
1. Log out of the active CP blade and log in to the standby CP blade.
2. Type
firmwareDownload -s to download the firmware to the standby CP blade. The -s option also disables the autoreboot, so
you will have to manually issue a reboot after the download finishes to initiate firmwarecommit. Enter all requested information
(use default values).
3. Type firmwareDownloadStatus to verify that the firmware has been updated.
4. Ensure that you are still logged in to the standby CP blade (the blade for which you just changed the firmware level) and type
reboot . The reboot of the standby CP will initiate a firmwarecommit to the secondary partition and log you out.
5. Log back in to the standby CP blade and type firmwaredDownloadStatus on the standby CP blade to validate a successful
commit. This may take 10 minutes.
6. Log out of the standby CP blade and log in to the active CP blade.
7. Type
haEnable to re-enable HA on the active CP blade.
NOTE
For Fabric OS 6.3.0 and later, haEnable will cause the standby CP blade to reboot. Wait until the power cycles and the
POST completes before moving to the next step.
8. Type haShow and verify that the command output includes "HA Enabled Heartbeat Up". If not, re-enter the command until you
have verified that redundancy is achieved.
9. Type version or firmwareShow to verify that the firmware version has been updated.
10. Pack the faulty CP blade in the packaging provided with the new CP blade, and contact the Brocade DCX supplier to determine
the return procedure.
11. Replace the chassis door ( Removal and replacement of the chassis door on page 83).
