DGX H100/H200 System Firmware Update Guide Version 25.04.3#

Highlights#

  • Improved handling for firmware update of PSUs.

  • Improved reporting on ERoT status.

  • Provided multiple stability fixes.

  • Improved user management in Redfish.

  • Enhanced stability in communication between the BMC and the HMC.

BMC Fixes#

  • Corrected power supply sensors where no readings were shown.

  • Fixed the inability to query GPU firmware version via Redfish.

  • Addressed an issue where some telemetry information from the GPU tray was unavailable.

  • Resolved an issue related to chassis power cycling using Redfish.

  • Corrected fan readings so the fan will reflect 0 if it is not present or stops spinning.

  • Fixed an issue where NIC information was allocated to the incorrect device in Redfish.

SBIOS Fixes#

  • Fixed an issue where the total memory size from the free -m command output is smaller than installed.

  • Updated to display full device path for HDD devices under the Redfish BootOptions page.

  • Fixed an issue to mandate administrator password after version 24.09.1 if SED drive is encrypted.

The nvfwupd Command Updates#

  • Added support for parallel firmware updates through the YAML configuration file.

  • Added the --json option to the update_fw, show_update_progress, and force_update commands.

  • Added IPv6 support.

  • Deprecated the targets sub-option for multi-target input. Use config.yaml input instead.
