Have you looked at the IBTA Integrators List to see if these cables have been tested and passed both FDR compliance and Interop. In our experience, non-compliant cables or old HCA firmware are the most common cause for links not supporting full FDR rates.

Yes, i tried switching that flag, it doesn't seem to make a difference.

as for the cables, they were supplied by Cray.  i haven't specifically checked them, but i trust they are FDR capable.

i did bounce the links and the whole machine, but it seems to keep coming up in that state.

me either, i reset back to a completely default opensm config and it still trips Bad Q_Key and doesn't let me actually talk on the fabric.
the port shows LinkUp, but smpquery/ipoib data fail

is there a possibility that there's a programming error on the fabric with the partitions, because i have QDR and FDR adapters on the same fabric.  perhaps something it can't figure out on its own and i have to hard code into the config?
