Switching control boards is not something to be done lightly. At a minimum, 
you have to power off the entire platform and/or delete all your domains. 
Gee, where did my data go again?

To switch control boards, do the following:

#.  Power off the entire E10K except the control boards. If it's not 
    possible to power everything off except the control boards, you'll have 
    to domain_remove all the domains.
#.  Update the name service, if necessary, for the new control board address 
    including the /etc/ethers if the mac address has changed.
#.  Run ``ssp_config cb`` on the SSP and specify the new configuration 
    information.
#.  Reboot the SSPs
#.  Using ``hostview``, ensure the J and C symbols show upin the display 
    control board squares. This signifies that the control boards are active.
#.  Power on the E10K and/or recreate the domains.
#.  Use ``bringup`` to restart your domains.
