Hello Folks,
Using auto lp-syc is a good improvement over the previous methods of upgrading 
a line card, but there are times it may not do the trick. Because the 
management modules also use an FPGA (the mbridge) to communicate with the 
backplane, you can run into a situation where the older module's FPGA image 
cannot talk to the management module. The LP and management modules have their 
own separate out-of-band network that bypasses the backplane, so auto-lp will 
attempt to stop the reboot cycle and use this connection to push the correct 
code to a misbehaving LP. Unfortunately, this may not work in every situation, 
so you may need to manually upgrade the code.

If you have a linecard constantly rebooting, you should use "boot lp 3 
interactive" from Enable mode to force the card to start in interactive mode 
(this will stop the reboot loop). You can then push the correct software and 
fpga image to the card. I tend to use the older "copy tftp image" method 
because it will automatically copy the correct IronWare LP code and you can 
target a specific LP with it vs. the whole chassis. I also use "copy tftp lp 
.... Fpga-all lp 3" to automatically sync the correct FPGA code to a specific 
module.

Alternately, you can use the new "copy tftp system" method to automatically up 
grade all code and fpga images on an LP. The command should only push to a 
module that needs to be upgraded, but I would make sure you have an outage 
window if you do this on a live system.

There is some good guides on doing this at the Brocade Communities site and the 
software upgrade guide for each version of IronWare has details notes on how to 
use the methods I mentioned and how to fix common problems when things go 
wrong. Check my.brocade.com for more info.

Your application image doesn't match then most likely.

Somehow the linecard doesn't recognize the difference between some 5300x and 
5400x application images, so it doesn't do an automatic lp sync on boot. Also 
attempting a manual lp sync doesn't see a problem.

Boot the card in interactive/monitor mode ('rcon lp 3' from console to get into 
the linecard shell and hit the b when it says so) and then make sure you 
upgrade the lp monitor, boot, application, xpp, sp2 and xgmac images from the 
generic commandline in your XMR. Then powercycle the linecard with a power-off 
and power-on and and it should work.

Thanks to all who answered including private mails.

It was not a problem of wrong module type in configuration etc.

I've downgraded IronWare to 5.2 and now modules are ok:



telnet at NetIron<http://puck.nether.net/mailman/listinfo/foundry-nsp> MLX-16 
Router#show module

        Module                             Status      Ports  Starting MAC

M1 (upper): BR-MLX-MR2-M Management Module     Active

M2 (lower):

F1: NI-X-HSF Switch Fabric Module         Active

F2: NI-X-HSF Switch Fabric Module         Active

F3: NI-X-HSF Switch Fabric Module         Active

F4:

S1: NI-MLX-10Gx8-D 8-port 10GbE (D) Module  CARD_STATE_UP       8        
0024.38a1.c900

S2: NI-MLX-10Gx8-D 8-port 10GbE (D) Module  CARD_STATE_UP       8        
0024.38a1.c930





I will try upgrading to 5.3 later once more time in order to check whether

it causes that problem.

Hi,

we were facing the same problem with a BR-MLX-10Gx4-X card in an XMR chassis. 
The card constantly rebooted after the message

  rw2_cpu_pkt_buf_init : rx_priority_mode set failed after 6 tries.

We were running software 5.3.0b. We performed an upgrade to 5.3.0c and after 
that all was fine:

#show module
        Module                             Status      Ports  Starting MAC
M1 (left): NI-XMR-MR Management Module     Active
..
S3: BR-MLX-10Gx4-X 4-port 10GbE Module  CARD_STATE_UP   4        748e.f85c.2d60

It presume therefore there is an issue with version 5.3.0b in relation with 
this linecard.

Best,
  - Jeroen
