MGX GH100 or Grace Hopper Update Examples#

This chapter provides information about the updating firmware on MGX Grace Hopper with tool usage examples.

Displaying the Firmware Contents on the System and the Package#

This command completes the following tasks:

  • Displays the versions of the firmware installed in the system.

  • Displays the versions of the firmware packages included with the -p option.

  • Compares the versions installed in the system and the packages with the -p option.

Here is the output:

$ nvfwupd -t ip=<BMC IP> user=*** password=*** servertype=MGX show_version -p nvfw_Grace-CPU-P5041_0003_231109.1.4_prod-signed.fwpkg

Activating the Firmware#

After performing firmware update of a component, or a full bundle, complete an AC power cycle to activate the new firmware. It can take up to five minutes for the BMC and the Redfish service to come up after the power cycle is complete. To check new system versions after the BMC Redfish service is back, run the show version command.

Updating the Firmware of Selected Components#

The example in this section shows you how to update a component from the system firmware inventory.

Important

The examples are applicable only to NVIDIA MGX GH100.

To perform component updates for a Grace Hopper platform:

  1. In the AP Name column, in the show_version output, select the AP to update and create a JSON file.

  2. Replace <AP name from show_version output> with the name you selected:

$ cat updparams.json
{
    "HttpPushUriTargets" :["/redfish/v1/UpdateService/FirmwareInventory/<AP name from show_version output>"]
}

For example, to update only the BMC firmware on a target:

  1. Get the component name for the BMC from the show_version output.

  2. Create a JSON file like updparams.json (refer to the output).

  3. Run the update_fw command with the -s option.

$ cat updparams.json
{
    "HttpPushUriTargets": ["/redfish/v1/UpdateService/FirmwareInventory/BMC_Firmware"]
}

$ nvfwupd -t ip=<BMC-IP> user=*** password=*** servertype=MGX update_fw -p nvfw_GH200-P5042_0004_230824.1.0_prod-signed.fwpkg -s updparams.json
FW package: ['nvfw_GH200-P5042_0004_230824.1.0_prod-signed.fwpkg']
