[f-nsp] Upgrading IOS on a MLX-8

[Mr. Dickerson]

I have upgrade numerous MLX's, as I work for Brocade in their Professional 
Services group. The process to upgrade an MLX is a little more complex than you 
may realize, especially since you are going from such an old code level to the 
latest (as a few others have pointed out).

First off, DO NOT attempt to use the combined image until you are at a minimal 
of code level 5.0. Trying to use the image on a code version any earlier, and 
you will have issues. 


Secondly, if you are running MRJ21 or any form of 10GB modules, the combined 
image will not work, as it does not have the correct images. You have to upgrade 
these line cards separately. 


Do not forget to upgrade your mbridge image. Follow the directions in the 
manual, for deleting the existing mbridge_old image or you will have issues if 
you try to back out of your upgrade. 


Be prepared to spend at a minimal of 30 minutes per MLX to do all the steps 
required to do the upgrade. You will be loading many images during this time, 
and it is very important that you keep track of where you are at in the process. 


If it helps you, here is a list of commands to upgrade an MLX-8 with 8-port 10GB 
modules and 24-port Copper GE modules. These are the all the images that are 
needed to upgrade the management, SFM, mbridge, and line cards which are 
installed. In our case, these were new "out of the box" MLX's so we did not have 
to delete the existing mbridge_old image first.

That won't brick anything, just cause it to probably not forward packets over 
that linecard.  Not an issue with proper OOB access via the MR.

If you want brickage, load a firmware version that predates support for that 
particular linecard (not really possible on XMR), or muck up the boot image on a 
linecard.  The FPGAs just work - or don't, but you don't interact with them 
directly.

"reload-check" is a good tip, though.
