Test and restore firmware on enterprise-class platforms

9

Testing different firmware versions on enterprise-class platforms

1. Connect to the Brocade enterprise-class platform IP address.

2. Enter the ipAddrShow command and note the address of CP0 and CP1.

3. Enter the haShow command and note which CP is active and which CP is standby. Verify that 

both CPs are in sync. 

4. Enter the firmwareShow command and confirm that the current firmware on both partitions on 

both CPs is listed as expected.

5. Exit the session.

6. Update the firmware on the standby CP.

a. Connect to the enterprise-class platform and log in as admin to the standby CP.

b. Enter the firmwareDownload -s command and respond to the prompts. 

At this point, the firmware should download to the standby CP only. When it has completed 
the download to that CP, reboot it. The current enterprise-class platform session will be 
disconnected.

7. Fail over to the standby CP.

a. Connect to the enterprise-class platform on the active CP.

b. Enter the haShow command to verify that HA synchronization is complete. It will take a 

minute or two for the standby CP to reboot and synchronize with the active CP. 

CAUTION

If you are downgrading from Fabric OS v6.2.0 to v6.1.0, your CPs will not gain synchronization 
and this will be a disruptive firmware download. Refer to 

 on page 191 for more 

information on synchronization states.

c. Enter the firmwareShow command to confirm that the primary partition of the standby CP 

contains the new firmware.

d. Enter the haFailover command. The active CP will reboot and the current enterprise-class 

platform session will be disconnected.

If an AP blade is present: At the point of the failover an autoleveling process is activated. 
See, 

 on page 196 for 

details about autoleveling.

8. Verify the failover.

a. Connect to the enterprise-class platform on the active CP, which is the former standby CP.

b. Enter the haShow command to verify that the HA synchronization is complete. It will take a 

minute or two for the standby CP, which is the old active CP, to reboot and synchronize with 
the active CP.

NOTE

If the CPs fail to synchronize, you can still proceed because the version being tested is already 
present on the active CP, and subsequent steps will ensure that the standby CP is updated to 
the same version as the active CP.
