Do you have an OpenFabrics-based network? (e.g., InfiniBand or iWarp) If so, this error message usually means that OFED is either installed incorrectly, or is not running properly (e.g., its services didn't get started properly upon boot).
If you don't have an OpenFabrics-based network, then it usually means that you have OpenFabrics services running when you really shouldn't (because you don't have any OpenFabrics-based devices).
