Control processor blade (CP8) removal and replacement

5

6. If both CP blades are healthy and you want to replace the active CP blade, log in to the active 

CP blade and run the following steps:

a. Run the haFailover command to make the standby CP blade the active blade. The currently 

active CP blade becomes the standby blade. Wait until the status LED on the currently 
active CP blade is no longer lit.

b. Confirm the completion of the failover by running the haShow command.

c. Log in to the new active CP blade.

7. Run firmwareShow to note the firmware version of the active CP blade.

The following example shows the results of the firmwareshow command when the firmware 
versions on the two CP blades are not the same. Note the warning message at the end of the 
output.

8. Run haDisable from the active CP blade to prevent failover or communication between the CP 

blades during the replacement.

9. Use the configUpload command to upload the backbone configuration to a specified FTP 

server. Enter information at the prompts.

a. Run the fosconfig --show command to determine if virtual fabrics are enabled. If so, run 

the configupload -vf command. This command uploads the Brocade DCX 8510-4 virtual 
fabric data.

b. If virtual fabrics are not enabled, run the configupload command. This command uploads 

the Brocade DCX 8510-4 configuration.

Removing a control processor blade (CP8)

For this procedure, please refer to 

The chassis continues to operate while a CP blade is being replaced if the redundant CP blade is 
active and a failover does not occur. You can prevent failover by entering the haDisable command.

Complete the following steps to remove a CP8 control blade (CP).

1. Remove the chassis door.

2. Log in to the active CP as the admin user. You can use a serial cable or Telnet, Web Tools, or 

Fabric Manager. Determine which CP is active using the haShow command or view the active 
LED on the front of the CP.
