Please, make sure to have active subnet manager on your InfiniBand fabric - it is essential for IPoIB operation.

Well, changing the MTU and using datagram mode did not fix things. I suspect that the problem lies in the difference between what ifconfig shows and what the ip command shows. The fact that ip says "NO-CARRIER" and "state DOWN" seems to indicate that the interface is not completely functional in the IPoIB world. I don't understand why ip thinks there is no carrier, yet the status lights on the HCAs and switch are ok and everyone seems to be communicating ok on the InfiniBand side of things. I did some further experimentation and hooked up the other InfiniHost HCA to our existing network. I see the same symptoms there, i.e. "ip show device" shows no carrier and the interface state is down. Does this indicate that there is some problem with IPoIB on Fedora9? We are running kernel 2.6.26.6-79.fc9.x86_64. Is there some IPoIB debug I can turn on somehow? _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
