We found what the problem is...
There is an onboard mthca DDR interface and a mlx4 QDR add-in card.
When the system comes up, it finds the onboard HCA first and was
making that IB0. The ifconfig output shows that interface ib0 is up
even though the actual IB state is down/polling. We disabled the

I checked another working fabric here and also see the same warnings,
so it looks like the warnings are not really a problem.
Well, I assume that it is just IPoIB that isn't working. Since ibping
works, I believe that says the IB part is ok. Of course, I can't run
any of the perftools since they

BTW, I am able to communicate between nodes via 'ibping'. That is the
only test program I found that will work without needing a host IP.

Sure, here is the output:
Note this is with the switch we swapped in, so the port numbers don't
match the ibchecknet output in the original message.
# ibstat

Hello,
We installed 1.5.1 and are having problems getting the IB fabric
working. ibv_devinfo shows the HCAs ports are ok and ibdiagnet reports
no errors. However, ibchecknet shows that the switch ports are not
being configured. We have never seen this before and are at a loss as
to where the prob
