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.

Note

The following table shows the mapping information between the slot numbering in XCC and physical GPU sockets.

Slot numbering in XCC	Physical GPU sockets	Location of the GPU sockets
Slot 17	GPU 5
Slot 18	GPU 7
Slot 19	GPU 8
Slot 20	GPU 6
Slot 21	GPU 1
