Updating the NVMe Firmware#

The following instructions describe how to update the firmware on an NVMe device using the NVME-CLI command-line interface. The nvme-cli tool is preinstalled on all DGX H100/H200 systems.

List the devices and check the firmware versions.

$ sudo nvme list

From the output, you can find the device names and firmware versions, such as /dev/nvme0n1 and GDC7302Q.

Download the firmware you want to upgrade for the NVMe device.

Based on the command output in step 1, determine the firmware file using the following table and include the correct path to download the firmware:

$ sudo nvme fw-download $DeviceName --fw=***(specify the firmware file for upgrade)

This table lists the firmware file names for the supported Samsung and Kioxia models:

Manufacturer	Model Number	Firmware File
Samsung	MZ1L21T9HCLS-00A07	`General_PM9A3_M.2_GDC7502Q_Noformat.bin`
Samsung	MZWLO3T8HCLS-00A07	`General_PM1743_U.2_OPPA4B5Q.bin`
Kioxia	KCM6DRUL3T84	`CM6-SED-0107.std`
Kioxia	KCM7DRUL3T84	`CM6-SED-0107.std`

Commit and activate the downloaded firmware immediately without reset by setting the action argument to 3.
```
$ sudo nvme fw-commit $DeviceName --action=3
```
Verify that the correct firmware version is updated.
```
$ sudo nvme id-ctrl $DeviceName
```
