Verifying and Synchronizing Firmware on Blades

About this task

At this point, the active blade is up and running. The replacement blade is the standby blade. Next, you must ensure that boot and POST are complete on the 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.

Procedure

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.
Log on to 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 Fabric OS Command Reference Manual.
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.
If the firmware versions for both CP blades are the same, skip to Completing the Replacement.

If the firmware version on the replacement (standby) and active CP blades do not match, a warning message appears with the results of the firmwareshow command.
```
WARNING: The local CP and remote CP have different versions
of firmware, please
```
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: To use this command, you must restart the existing telnet, secure telnet, or SSH sessions to the standby CP blade.
- 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.
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.
