    Multiple MCX455A-ECA showing GUID of 0x123


      I picked up a couple ConnectX4 single-port HCAs second-hand that are showing an invalid GUID. They all are showing 0123 for GUID and hardware version of 0. I've updated the firmware and OFED to the latest. I'm not sure what to do next. Are these cards faulty? Any ideas?

          It is possible that someone reflashed HCA's with wrong GUID's. However the HCA's may be fine.

          Try this:

          Install CentOS/RH7.5 (inbox driver should be fine, at least for testing)

          Set the port type to desired value (see MFT user manual, mlxconfig command)

          Connect hosts the with the EDR cable and if you are interested in checking IB, start opensm service

          Configure interfaces and run 'ifuip <IFs> up'

          Verify port state with ibv_devinfo
