    ib0: error fetching interface information: Device not found




      I have a Infiniband controller: Mellanox Technologies MT27600 [Connect-IB] in HP blades running CentOS6.8

      ifconfig ib0 keeps giving the error "fetching interface information: Device not found"


      I restarted the rdma service with no luck.

      #service rdma status

      Low level hardware support loaded:

              mlx5_ib mlx5_core


      Upper layer protocol modules:



      User space access modules:

              rdma_ucm ib_ucm ib_uverbs ib_umad


      Connection management modules:

              rdma_cm ib_cm iw_cm


      Configured IPoIB interfaces: ib0


      Currently active IPoIB interfaces: none


      Thank you in advance
