|
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 perftest -n 32 -o read -s 512 -t 30 nvme0ns1
|
|
.Pp
|
|
Run a performance test on nvme0ns1 using 32 kernel threads for 30 seconds.

.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

|
.Pp
|
|
.Dl nvmecontrol firmware -s 7 -f /tmp/nvme_firmware -a nvme0
|
|
.Pp
|
|
Download the firmware image contained in "/tmp/nvme_firmware" to slot 7 of the
|

.Dl nvmecontrol power -l nvme0
|
|
.Pp
