I must admit, I'm curious as to why one cannot use GPFS with IB and OPA both in RDMA mode. Granted, I know very little about OPA but if it just presents as another verbs device I wonder why it wouldn't "Just work" as long as GPFS is configured correctly.

I can see no reason why that wouldn't work. But it would be nice to a
have an official answer or evidence that it works.

All,

I see in the GPFS FAQ A6.3 the statement below.  Is it possible to
have GPFS do RDMA over EDR infiniband and non-RDMA communication over
omnipath (IP over fabric) when each NSD server has an EDR card and a
OPA card installed?



RDMA is not supported on a node when both Mellanox HCAs and Intel
Omni-Path HFIs are enabled for RDMA.
