Mellanox SwitchX-2 MLNX-OS Upgrade Stall via WebGUI and MLNX-OS to Onyx Upgrade?

Yesterday, we posted about our OS update process and the grids that indicated the proper path to the most current version.

A catch that became apparent was that there were two streams of updates available to us:

1. image-PPC_M460EX-3.6.4112.img
2. onyx-PPC_M460EX-3.6.4112.img
• ETC
• 

As can be seen in the snip above we read an extensive number of Release Notes (RN) and User Manuals (UM) trying to figure out what was what and which was which. :S

In the end, we opened a support ticket with Mellanox to figure out why our switches were stalling on the WebGUI upgrade process and why there was a dearth of documentation indicating anything about upgrade paths.

The technician mentioned that we should use CLI to clean-up any image files that may be left over. That's something we've not had to do before.

Following the process in the UM to connect via SSH using our favourite freebie tool TeraTerm we connected to both switches and found only one file to delete:

• WebImage.tbz

Once that file was deleted we were able to initiate the update from within the WebGUI without error on both switches.

Since we had MLNX-OS 3.6.4112 already installed the next question for the tech was, "How do we get to the most current version of Onyx?"

The process was as follows:

1. Up to MLNX-OS 3.6.4112
2. Up to Onyx 3.6.6000
3. Up to Onyx 3.6.8008

As always, check out the Release Notes (RN) to make sure that the update will not cause any problems especially with in-production NICs and their firmware!

Happy News! Welcome to Onyx
