Today i was updating 16 Switches within one Fabric from FabricOS 6.4.2b to 7.0.2b1
Switch types are: 2 times DCX-4S and the rest 5100
One of the DCX-4S shows the following behavior an it is not possible to update.
While CP1 was updated successfully i can't update CPU.
I get the following errormessage:

I alos tried another targetversion like 7.0.2e1 -> no success
I also tried a firmwaredownload -s -> no success
Unfortunaltely i can't find any explanation what error 0x126 means in detail.
Any idea what i could do to make it work ?

i run into Brocade DEFECT000373879.
Solution is to disable the co-cpu and then run the upgrade.
Got detailed instructions from Brocade support how to do this. (Procedure includes commands like "/sbin/bootenv/ Autoload no")
Thanks for all your replies and ideas.
