Updating Components with Secondary Images

Some firmware components provide a secondary image as backup. The following is the policy when updating those components:
  • SBIOS: The two images are referred to as active and inactive, where the active is the currenly running image and the inactive is the backup image. When using update_fw all, the update container updates both active and inactive images.
  • BMC: The two images are referred to as active and inactive, where the active is the currenly running image and the inactive is the backup image. The update container can only update the inactive image, and will update it only if the active image needs to be updated. After the update is completed, the updated inactive image becomes the active image. Because the active image is now updated, subsequent update_fw all commands will not update the inactive image. To update the inactive image in this case, use update_fw BMC --inactive.

Updating the CEC 1712 (Delta-CEC)

The firmware update container may fail to update the Delta_CEC. To work around, perform the following.
  1. sudo ./nvfw-dgxa100_21.03.6_210321.run update_fw CEC -s Delta_CEC -m
  2. sudo ipmitool chassis power cycle
  3. sudo ./nvfw-dgxa100_21.03.6_210321.run update_fw all


When updating DGX A100 firmware using the Firmware Update Container, do not update the CPLD firmware unless the DGX A100 system is being upgraded from 320GB to 640GB.

The current DGX A100 Firmware Update Container will not automatically update the CPLD firmware (for example, when running update_fw all). It is possible to update the CPLD firmware using “update_fw CPLD”; however, it is strongly recommended that the CPLD firmware not be updated manually unless specifically instructed by NVIDIA Enterprise Support (or email enterprisesupport@nvidia.com). If the DGX A100 is upgraded from 320GB to 640GB, the CPLD firmware update should be performed as instructed.

Special Instructions for Red Hat Enterprise Linux

This section describes the actions that must be taken before updating firmware on DGX A100 systems installed with Red Hat Enterprse Linux. There are two options for meeting these requirements.

Option 1: Update to EL7-21.01 or later

Refer to the DGX Software for Red Hat Enterprise Linux 7 Release Notes for more information.
Important: Updating the DGX software for Red Hat Enterprise Linux will update the Red Hat Enterprise Linux installation to 7.9 or later. If you do not want to update your Red Hat Enterprise Linux 7 installation, then choose Option 2.

Option 2: Install mpt3sas

These instructions apply if
  • You do not want to update your Red Hat Enterprise Linux installation, and
  • Your system is currently installed with Red Hat Enterprise Linux 7.7 or later.

    If your system is installed with Red Hat Enterprise Linux 7.6 or earlier, contact NVIDIA Enterprise Support for assistance.

  1. Perform this step if your system is no longer pointing to the NVIDIA DGX software repository.
    1. On Red Hat Enterprise Linux, run the following commands to enable additional repositories required by the DGX software.
      sudo subscription-manager repos --enable=rhel-7-server-extras-rpms
      sudo subscription-manager repos --enable=rhel-7-server-optional-rpms
    2. Run the following command to install the DGX software installation package and enable the NVIDIA DGX software repository.

      Attention:By running these commands you are confirming that you have read and agree to be bound by the DGX Software License Agreement. You are also confirming that you understand that any pre-release software and materials available that you elect to install in a DGX may not be fully functional, may contain errors or design flaws, and may have reduced or different security, privacy, availability, and reliability standards relative to commercial versions of NVIDIA software and materials, and that you use pre-release versions at your risk.
      yum install -y \
  2. Install mpt3sas
    sudo yum install mpt3sas-dkms
  3. Load the mpt3sas driver into the Red Hat Enterprise Linux kernel.
    sudo modprobe mpt3sas 
    You can verify the correct mpt3sas version is installed by issuing the following.
     yum list installed

Instructions for Updating Firmware

This section provides a simple way to update the firmware on the system using the firmware update container. It includes instructions for performing a transitional update for systems that require it. The commands use the .run file, but you can also use any method described in Using the DGX A100 FW Update Utility.
  • Stop all unnecessary system activities before attempting to update firmware.
  • Stop all GPU activity, including accessing nvidia-smi, as this can prevent the VBIOS from updating.
  • Do not add additional loads on the system (such as user jobs, diagnostics, or monitoring services) while an update is in progress. A high workload can disrupt the firmware update process and result in an unusable component.
  • When initiating an update, the update software assists in determining the activity state of the DGX system and provides a warning if it detects that activity levels are above a predetermined threshold. If the warning is encountered, you are strongly advised to take action to reduce the workload before proceeding with the update.
  1. Check if updates are needed by checking the installed versions.
    $ sudo ./nvfw-dgxa100:21.03.6_210321.run show_version
    • If there is "no" in any up-to-date column for updatable firmware, then continue with the next step.
    • If all up-to-date column entries are "yes", then no updates are needed and no further action is necessary.
  2. Perform the update for all firmware supported by the container.
    $ sudo ./nvfw-dgxa100:21.03.6_210321.run update_fw all
    Depending on the firmware that is updated, you may be prompted to either reboot the system or power cycle the system.
    • If you are prompted to reboot, issue
      $ sudo reboot
    • If you are prompted to power cycle, you can issue the following two commands (there is no output with the first command).
      $ sudo ipmitool raw 0x3c 0x04
      $ sudo ipmitool chassis power cycle
  3. After rebooting or power cycling the system, you may need to perform another update_fw all to update other firmware.
    • Either repeat Step 1 to check if updates are needed and then perform Step 2 if needed, or
    • Repeat Step 2 just in case updates are needed.
    If you perform another update_fw all, you may be prompted again to either reboot the system or power cycle the system. See DGX A100 Firmware Update Process for more information about the update process.
You can verify the update by issuing the following.
$ sudo ./nvfw-dgxa100:21.03.6_210321.run show_version

Known Issues

BMC UI May not be Accessible from Mac OS


When attempting to connect to the DGX A100 BMC from a system with Mac OS, a "Your connection is not private" message appears that prevents access to the BMC.


Starting with version 0.13.6, the BMC provides a self-signed certificate which Mac OS flags in the browser. Most browsers will let you either accept the risk and continue, or add the certificate to the keychain and continue. The Chrome and Opera browsers, however, do not provide these options and so Mac OS users will not be able to access the BMC from the Chrome or Opera browser.

To access the DGX A100 BMC, Mac OS users can use Safari or Firefox, which provide an access path.

Boot Order in the SBIOS Reverts to the Default


After updating the SBIOS, any changes in the boot order that you have made are not preserved and the boot order specified in the SBIOS reverts to the following.

Boot Option #1  [Hard Disk]
Boot Option #2  [NVME]
Boot Option #3  [USB CD/DVD]
Boot Option #4  [USB Hard Disk]
Boot Option #5  [USB Key]
Boot Option #6  [Network]


You will need to prepare for the change when restarting the system, and then enter the SBIOS setup to edit the boot order as needed.

Unable to Launch BMC Dashboard under Pre-84.01 Firefox


After updating the BMC, attempts to access the BMC dashboard using Firefox versions earlier than 84.01 fail with a "Secure Connection Fail" message.


To work around, update Firefox to version 84.01 or later.

The system starts the POST process several times during boot after updating the SBIOS.


After updating the SBIOS and rebooting the system, the NVIDIA splash screen appears and disappears several times before boot is completed.


After updating the SBIOS, several component states are cleared and the system may reboot automatically 3-4 times to reset all the components. This is expected behavior.
