Verifying and synchronizing firmware on blades

At this point, the active blade is up and running. The replacement blade is the standby blade. To verify that boot and POST are complete
on a newly installed CP blade, that the CP blade has achieved failover redundancy, and that firmware levels are synchronized on the
installed blades, perform the following steps.

1. Enter

slotShow

. The command output shows the new CP blade as "enabled."

If the standby CP is unresponsive, you can try unplugging the new CP blade, running

haDisable

on the active CP blade, and

plugging the new CP blade back in. At that point, you can repeat step 1 to begin the verification process again.

2. Log into each CP blade and enter the

haShow

command to display the CP status. Verify the CP state, status, health, and that

the HA state is synchronized. Remedy any issues before proceeding. For more information on

haShow

output, refer to the

Brocade Fabric OS Command Reference

3. Determine the firmware version of installed CP blades by entering

firmwareShow

. If the serial console on the replacement CP

blade is connected, issue the

firmwareShow

command there. More information is available through the console.

4. If the firmware versions for both CP blades are the same, skip to

Completing the replacement

on page 164.

If the firmware version on the replacement (standby) blade does not match that on the active CP blade, a warning message
appears with the results of the

firmwareshow

command.

WARNING: The local CP and remote CP have different versions

of firmware, please

5. Bring the replacement blade firmware to the same firmware level as the active blade using one of the following procedures:

•

Run the

firmwaresync

command on the active CP blade to copy all firmware from the active CP blade to the standby CP

blade.

NOTE

Using this command requires that existing telnet, secure telnet, or SSH sessions to the standby CP blade to be
restarted.

•

Run the

firmwareDownload -s

command or

firmwaresync

command (if versions are compatible) to update firmware on

the replacement blade to bring it up to the proper level.

6. Perform one of the following tasks to download firmware:

•

If you are using an FTP server to download the firmware, skip to the procedure for downloading firmware from an FTP
server.

•

If you are using a USB device to download the firmware, skip to the procedure for downloading firmware from a USB
device. 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

Brocade Fabric OS Upgrade Guide

Downloading firmware from FTP server

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 an FTP server to the replacement blade.

1. Log in to the standby CP blade as

admin

. If you need to know the IP address of the standby blade, run
