Health check for GPUs

Note

Use one of the following utilities to check the GPU health status. Make sure to update GPU driver, which includes the following utilities required. Latest driver can be found at Drivers and Software download website for ThinkSystem SR780a V3.

For more information about System Management Interface (SMI) information, see NVIDIA System Management Interface.

  • nvidia-smi

    Run the nvidia-smi utility to display the eight GPUs online.

    Note
    GPU numbers (0 to 7) in the output are the logical numbers. The following table shows the mapping information between the logical numbers and physical GPU sockets.

  • nvidia-smi -q --id=1 -f <output file name>

    Run the nvidia-smi -q --id=1 -f <output file name> utility to export GPU inventory information.

    Type the desired file name in <output file name> to store the output. For example: nvidia-smi -q --id=1 -f /tmp/queryoam1.txt.

  • nvidia-smi --id=0 -q -d ECC,PAGE_RETIREMENT

    Run the nvidia-smi --id=0 -q -d ECC,PAGE_RETIREMENT utility to export ECC (Error Checking and Correction) errors and status of retired pages.

  • nvidia-smi pci --getErrorCounters --id=<id number>

    Run the nvidia-smi pci --getErrorCounters --id=<id number> utility to display error counters of a specific GPU.

    Type the ID number of a specific GPU in <id number>. For example: nvidia-smi pci --getErrorCounters --id=2.

System fails to detect a specific GPU

When one of the events appears in the XCC web event log, it indicates the system fails to detect one or more specific GPUs.

  • When event FQXSPIO0015M: Fault in slot [PhysicalConnectorSystemElementName] on system [ComputerSystemElementName]. appears, see FQXSPIO0015M to solve the problem.
  • When event FQXSFIO0010M: An Uncorrectable PCIe Error has Occurred at Bus [arg1] Device [arg2] Function [arg3]. The Vendor ID for the device is [arg4] and the Device ID is [arg5]. The physical [arg6] number is [arg7]. appears, see FQXSFIO0010M to solve the problem.
    Note
    Parameters:
    • [arg1] Bus
    • [arg2] Device
    • [arg3] Function
    • [arg4] VID
    • [arg5] DID
    • [arg6] Slot/Bay
    • [arg7] Instance number
  • When event FQXSPUN0019M : Sensor [SensorElementName] has transitioned to critical from a less severe state. appears, see FQXSPUN0019M to solve the problem.
