Sorry.  I think I misread your original email.  So your server has both tcp and o2ib NIDs, and you want the server to route requests from tcp clients to other resources on the o2ib network.  But when you mount Lustre, you want the client to use the server’s o2ib NID instead of mounting with the server’s tcp NID.  Is that correct?
