NVME-FW-COMMIT(1) NVMe Manual NVME-FW-COMMIT(1)

NAME

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

SYNOPSIS

   nvme fw-commit <device> [--slot=<slot> | -s <slot>]
                           [--action=<action> | -a <action>]
                           [--bpid=<boot-partid> | -b <boot-partid>]
                           [--output-format=<fmt> | -o <fmt>] [--verbose | -v]
                           [--timeout=<timeout> | -t <timeout>]

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.

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.

   -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)

   -o <fmt>, --output-format=<fmt>
       Set the reporting format to normal, json or binary. Only one output format can be used at a time.

   -v, --verbose
       Increase the information detail in the output.

   -t <timeout>, --timeout=<timeout>
       Override default timeout value. In milliseconds.

EXAMPLES

   •   commit the last downloaded fw to slot 1.

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