If there are multiple node EGs (encryption groups) in a fabric, please complete firmwaredownload on one node
at a time before downloading on another node.
The Brocade 8000 does not support non-disruptive hot code loads (HCL). Upgrading the Brocade 8000 to FOS
v6.4 will be disruptive to the IO through the switch.
A code load of DCX or DCX-4s with one or more FCOE10-24 blades will disrupt the traffic going through those
FCOE10-24 blades.

message. This step is necessary even if users do not plan to use FC8-64 blades after performing firmware
upgrade to FOS v6.4. However, if areas 0x70-0x8F are not in use this step is not necessary. Please use
portAddress CLI to find out the areas in use within a Logical Switch.

This is
necessary to load the new FPGA image that enables IPv6 capability for FCIP links to 7800 and FX8-24 blade.
This step is mandatory even if IPv6 will not be used on the FCIP ports. Not performing this step will result in
unpredictable behaviors on the FCIP links. Please note that in the case of FX8-24, only the FX8-24 blade needs
to be power cycled and not the entire DCX/DCX-4S chassis.
