a new firmware command. NVMe controllers may support up to 7 firmware slots for storing of different firmware revisions. This new firmware command supports firmware replacement (i.e. firmware download) with or without immediate activation, or activation of a previously stored firmware image. It also supports selection of the firmware slot during replacement operations, using IDENTIFY information from the controller to check that the specified slot is valid. Newly activated firmware does not take effect until the new controller reset, either via a reboot or separate 'nvmecontrol reset' command to the same controller.

.Sh DESCRIPTION
|
|
NVM Express (NVMe) is a storage protocol standard, for SSDs and other
|
|
high-speed storage devices over PCI Express.
|
|
.Sh EXAMPLES
|
|
.Dl nvmecontrol devlist
|
|
.Pp
|
|
Display a list of NVMe controllers and namespaces along with their device nodes.
|
|
.Pp
|
|
.Dl nvmecontrol identify nvme0
|
|
.Pp
|
|
Display a human-readable summary of the nvme0 IDENTIFY_CONTROLLER data.
|
|
.Pp
|
|
.Dl nvmecontrol identify -x -v nvme0ns1
|
|
.Pp
|
|
Display a hexadecimal dump of the nvme0 IDENTIFY_NAMESPACE data for namespace
|
|
1.
|
|
.Pp
|
|
.Dl nvmecontrol perftest -n 32 -o read -s 512 -t 30 nvme0ns1
|
|
.Pp
|
|
Run a performance test on nvme0ns1 using 32 kernel threads for 30 seconds. Each
|
|
thread will issue a single 512 byte read command. Results are printed to
|
|
stdout when 30 seconds expires.
|
|
.Pp
|
|
.Dl nvmecontrol reset nvme0
|
|
.Pp
|
|
Perform a controller-level reset of the nvme0 controller.
|
|
.Pp
|
|
.Dl nvmecontrol logpage -p 1 nvme0
|
|
.Pp
|
|
Display a human-readable summary of the nvme0 controller's Error Information Log.
|
|
Log pages defined by the NVMe specification include Error Information Log (ID=1),
|
|
SMART/Health Information Log (ID=2), and Firmware Slot Log (ID=3).
|
|
.Pp
|
|
.Dl nvmecontrol logpage -p 1 -x nvme0
|
|
.Pp
|
|
Display a hexidecimal dump of the nvme0 controller's Error Information Log.
|
|
.Pp
|
|
.Dl nvmecontrol firmware -s 2 -f /tmp/nvme_firmware nvme0
|
|
.Pp
|
|
Download the firmware image contained in "/tmp/nvme_firmware" to slot 2 of the
|
|
nvme0 controller, but do not activate the image.
|
|
.Pp
|
|
.Dl nvmecontrol firmware -s 4 -a nvme0
|
|
.Pp
|
|
Activate the firmware in slot 4 of the nvme0 controller on the next reset.
|
|
.Pp
|
|
.Dl nvmecontrol firmware -s 7 -f /tmp/nvme_firmware -a nvme0
|
|
.Pp
|
