    My one of the Mellanox card is not getting recognized as infiniband/roce device

    am2014

      Hi,

      I have ConnectX3 Pro adapter on my rhel 7.0 system.

       

      Red Hat Enterprise Linux Server release 7.0 (Maipo)

      lspci | grep -i mel

      02:00.0 Network controller: Mellanox Technologies MT27520 Family [ConnectX-3 Pro]

       

      I have Mellanox OFED on my system.

      ofed_info -s

      MLNX_OFED_LINUX-3.0-1.0.1:

       

      This adapter is not getting recognized as IB/RoCE device there, pl see below:

      ibdev2netdev

      ls: cannot access /sys/class/infiniband/: No such file or directory

      ibv_devinfo

      Failed to get IB devices list: Function not implemented

       

       

      It gets recognized as NIC Interfce in ifconfig, whether MAC address seems to be good there?

      ens3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

              ether f4:52:14:77:f8:d0  txqueuelen 1000  (Ethernet)

              RX packets 198  bytes 27390 (26.7 KiB)

              RX errors 0  dropped 0  overruns 0  frame 0

              TX packets 0  bytes 0 (0.0 B)

              TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

       

       

      I have also tried with

      ofed_info -s

      MLNX_OFED_LINUX-3.1-1.0.3:

       

      and see same behavior.

       

      I want to configure this card for RoCE V2 RDMA_CM and it is not working properly.

       

      Can someone help please?

       

      Thanks.
