5. Log back in to the standby CP blade and run firmwareDownloadStatus on the standby CP blade to validate a
successful commit. This may take 10 minutes.
6. If you are upgrading through several levels of the Fabric OS, repeat step 2 through step 5 as often as necessary
based on the path outlined in the preceding table. Otherwise, proceed to step 7.
7. Log out of the standby CP blade and log in to the active CP blade.
8. Proceed to the procedures for verifying operation of the new CP blade.
Downloading firmware from a USB device
For this task, determine the correct sequence of upgrading firmware versions to reach your target version.
Complete the following steps to download the firmware from a USB device.
This section assumes that the new firmware has already been copied onto the USB device. The folder structure on the
USB device must be as follows in order to allow the device to be enabled:
•
brocade>
–
config
–
firmware
–
firmwareKey
–
support
The firmware folder contains the folder for the specific release you are installing.
1. Insert the USB device into the active CP blade.
2. Attach a serial cable from the PC to the active CP blade.
3. Log in to the active CP blade as admin if you are not still logged in and enter usbStorage -e to enable the USB
device.
4. Remove the serial cable from the active CP blade and attach it to the standby CP blade and log in as admin.
5. Run 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).
6. When the download process finishes, run firmwareDownloadStatus to verify that the firmware has been updated.
The command displays a running account of the progress of the firmwareDownload command until the command has
completed. The final message is similar to the following and will appear with a date and time stamp.
NOTE
The slot number for the CP blade is different for a chassis with slots for four port blades and a chassis with
slots for eight port blades. The slot number in the following example is for a chassis with slots for four port
blades.
Slot 4 (CP0, active): Firmwaredownload command has completed successfully. Use firmwareshow to verify the
firmware versions.
7. 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.
