We just had an "internal parity error" on a mellanox HCA. The HCA recovered. However, IPoIB did not fair as well. We are not sure of the details. What I have on the console is:

We tried to ifup ib0 and got: # zeus64 /root > ifup ib0 ib_ipoib ib_ipoib device ib0 does not seem to be present, delaying initialization. I then tried to unload the ib_ipoib module and that has hung for the last 15 min. I have run ibv_rc_pingpong and ib_rdma_bw through the node fine. ibstat and ibstatus and the switch show the link to be up. So it appears as though the card recovered fine. What can we do? :-/ Thanks, Ira _______________________________________________ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
