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

Thank you in advance
