Reposting: Chassis Management Module (CMM) Fails to Switch Over

Question

This post was originally posted on IBM’s developerWorks public forum (https://www.ibm.com/developerworks/community/forums/html/topic?id=f9164eb4-1a74-42b3-8348-28dfa24caf...  The following is a summary of the post issue and the response.
Issue:
I'm facing an issue regarding the PureFlex Chassis Management Module (CMM) failover scenario such that I have two CMM’s installed in a single chassis connected to two ports of a switch. 
When accessing the CMM through the IP address, the CMM is accessible. 
However, when the switch port connected to the active CMM is shutdown or disconnected, the CMM is not failing over to Standby and there is no ping response to CMM.
What is causing this behavior and how do I resolve it?

Ah, ok. I was in the assumption the PCI connect had something to do with the video connection. But it seems like Apple wanted to reinvented PCIe...
I'm out of my territory here so feel free to ignore the following.
These are the things I notice in your Xorg.0.log:
[    19.474] (==) modesetting(G0): Depth 24, (==) framebuffer bpp 32
[    19.474] (==) modesetting(G0): RGB weight 888
[    19.474] (==) modesetting(G0): Default visual is TrueColor
[    19.474] (II) modesetting(G0): ShadowFB: preferred YES, enabled YES
[    19.500] (II) modesetting(G0): Output VGA-1-0 has no monitor section
[    19.526] (II) modesetting(G0): EDID for output VGA-1-0
[    19.526] (II) modesetting(G0): Using default gamma of (1.0, 1.0, 1.0) unless otherwise stated.
[    19.526] (==) modesetting(G0): DPI set to (96, 96)
What the hell is modesetting doing there?
And have you tried the nvidia blob? It could be that this is not well supported by nouveau. Maybe check up with their IRC / mailing list.
