Error durinng FabricOS update "Firmwaredownload to co-CPU failed. (0x126)"

Hello Team,

 

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:

 

CXC0082:admin>

CXC0082:admin> firmwareshow

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 ?

 

 

Kind regards

 

Helmut

I think I've seen that before. It's a hardware problem, something like flash memory refuses to accept writes. You'll have to replace the problem CP.

Helmut,

 

firmwaredownload -s, start the upgrade on single CP.

 

have you tried to start the firmwaredownload -s on standby CP ?

Hello,

 

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.

 

 

Helmut
