[ofa-general] Direct / "Crossover" IPOIB

[Robert Dunkley]

I've just setup two machines linked by a single Inifiniband cable. The
IPOIB side of things looks OK, ifconfig shows the interface and each
machine can ping itself on its Infiniband IP. They cannot ping each
other though and ibstat looks wrong. What do I need to do to make this
setup work?

 

Thanks,

 

Rob
