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 B200 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 GDC7502Q.

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)
```
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
```
