NAME
nvme-fw-activate - Used to verify and commit a firmware image.
SYNOPSIS
nvme fw-activate <device> [--slot=<slot> | -s <slot>]
[--action=<action> | -a <action>]
DESCRIPTION
For the NVMe device given, send an nvme Firmware Activate admin command and provides the results.
The Firmware Activate 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 activate 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 activate the firmware by issuing
a reset through Linux sysfs, for example:
# echo 1 > /sys/class/misc/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>
Activate 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 Activate 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.
