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

       -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.

EXAMPLES

       •   Activate the last downloaded fw to slot 1.

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