# nvme-fw-commit(1) Manual Page

## NAME

nvme-fw-commit - Used to verify and commit a firmware image.

## SYNOPSIS

    nvme [<global-options>] fw commit <device> [--slot=<slot> | -s <slot>]
                            [--action=<action> | -a <action>]
                            [--bpid=<boot-partid> | -b <boot-partid>]

## DESCRIPTION

For the NVMe device given, send an nvme Firmware Commit admin command and provides the results.

The Firmware Commit command is used to verify that a valid firmware image has been downloaded and to commit that revision to a specific firmware slot. The host may select the firmware image to commit on the next controller reset (CC.EN transitions from ‘1’ to ‘0’, a PCI function level reset, and/or other Controller or NVM Subsystem Reset) as part of this command. The currently executing firmware revision may be determined from the Firmware Revision field of the Identify Controller data structure as indicated in the Firmware Slot Information log page.

No further action is automatically taken to reset the device, which is usually required to complete the activation process. If your kernel and driver are recent enough, you can commit the firmware by issuing a reset through Linux sysfs, for example:

     # echo 1 > /sys/class/nvme/nvme0/device/reset

If your kernel is not recent enough, you will need to remove and add the device some other way.

The bare nvme fw-commit form (without a space) still works as a deprecated alias and will be removed in a future major version. New scripts should use nvme fw commit instead.

## OPTIONS

-a <action>
--action=<action>

  Commit Action: This field specifies the action that is taken on the image downloaded with the Firmware Image Download command or on a previously downloaded and placed image.

  Value | Definition
  0 | replace | Downloaded image replaces the image indicated by the Firmware Slot field. This image is not activated.
  1 | replace-and-activate | Downloaded image replaces the image indicated by the Firmware Slot field. This image is activated at the next reset.
  2 | set-active | The image indicated by the Firmware Slot field is activated at the next reset.
  3 | replace-and-activate-immediate | The image specified by the Firmware Slot field is requested to be activated immediately without reset.
  6 | replace-boot-partition | Downloaded image replaces the Boot Partition specified by the Boot Partition ID field.
  7 | activate-boot-partition | Mark the Boot Partition specified in the BPID field as active and update BPINFO.ABPID.

-s <slot>
--slot=<slot>

  Firmware Slot: Specifies the firmware slot that shall be used for the Commit Action, if applicable. If the value specified is 0h, then the controller shall choose the firmware slot (slot 1 – 7) to use for the operation.

--bpid=<boot-partid>
-b <boot-partid>

  Specifies the Boot partition that shall be used for the Commit Action, if applicable (default: 0)

## GLOBAL OPTIONS

The following options are defined at the top-level `nvme` command and are available to this subcommand:

--dry-run

  Print the command that would be executed, but do not actually execute it.

--no-ioctl-probing

  Disable probing for 64-bit IOCTL support.

--no-retries

  Disable retry logic on transient errors.

-o <fmt>
--output-format=<fmt>

  Set the reporting format to normal, tabular, 'json, or binary. Only one output format may be used at a time.

--output-format-version=<version>

  Select the output format version. Version 1 uses the original field naming, while version 2 (default) provides more consistent and script-friendly field names.

--timeout=<ms>

  Set the timeout for the command in milliseconds.

-v
--verbose

  Increase the level of detail in the output. May be specified multiple times to further increase verbosity.

These options can also be set as machine-wide defaults in nvme-cli.conf(5). A command-line flag always overrides the file.

## EXAMPLES

- commit the last downloaded fw to slot 1.

      # nvme fw commit /dev/nvme0 --slot=1 --action=2
