I'm running 2.6.28 with 1 HCA with 2 ports. I added debug output around calls to rdma_translate_ip() and cma_acquire_dev(). The short answer is that things appear to work as expected. ib0 is on port 1 - 192.168.0.102 ib1 is on port 2 - 192.168.0.122 If I run ucmatose -b ip_addr (with or without -s option), I see that rdma_translate_ip() returns different net_device structures for the different input addresses. cma_acquire_dev() also indicates that different ports on the same HCA are being used for the two addresses. If I unplug one of the ports, I can no long connect if I use the IP address that corresponds to that port, but the other port still works. It doesn't matter which port I unplug, as long as I use the correct IP address. - Sean _______________________________________________ general mailing list general@lists.openfabrics.org http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
