Known Issues#

Functional Issues#

  • You cannot update firmware of the individual components of the DGX B300 GPU tray. For example, you can not individually update the firmware for the GPU only. You must update the firmware by flashing the entire DGX B300 GPU tray.

  • Firmware download is not automatic. You must download the firmware manually from the NVIDIA Enterprise Support Portal.

Intermittent Timeout During Update All Firmware Process#

Issue#

Executing the complete firmware update (using the update all operation) might intermittently result in exceptions or timeout errors. A timeout error occurs when the system fails to receive a response from the firmware task status service (#/FwTaskStatus) within the 120-second window.

Error Message:

"Message":"The timeout duration (120s) was exceeded before the operation on #/FwTaskStatus responded."

Workaround#

If you encounter this issue, retry the operation. A subsequent attempt typically succeeds without further intervention. If the TaskID displays the error message, retry querying the firmware task status service (TaskStatus).

Firmware Inventory Can Be Invalid During Boot#

Issue#

In rare instances, polling the firmware inventory endpoint of the BMC Redfish API can report an inaccurate firmware versions for the HGX_0 component.

Workaround#

Query the firmware inventory after the system completes the boot sequence to retrieve the current firmware inventory.

BMC Slow Startup After AC Power Cycle#

Issue#

Following an AC power cycle, the BMC typically becomes available within 3 minutes, although it might require up to 10 minutes to fully initialize.”

Workaround#

No workaround is available.
