NAME

6       nvme-get-property - Reads and shows the defined NVMe controller
7       property for NVMe over Fabric
8

SYNOPSIS

10       nvme get-property <device> [--offset=<offset> | -o <offset>]
11                                       [--human-readable | -H ]
12

DESCRIPTION

14       Reads and shows the defined NVMe controller property for NVMe over
15       Fabric.
16

OPTIONS

18       -o, --offset
19           The offset of the property. One of CAP=0x0, VS=0x8, CC=0x14,
20           CSTS=0x1c, NSSR=0x20
21
22       -H
23           --human-readable: Show the fields packed in the property
24

EXAMPLES

26       •   The following will run the get-property command with offset 0
27
28               # nvme get-property /dev/nvme0 --offset=0x0 --human-readable
29

BUGS

31       Currently the CAP value is truncated to 32 bits due to a limitation in
32       the ioctl interface.
33
34       In a recent enough kernel, the 64 bit value is shown in kernel traces.
35
36       •   First enable traces by this command
37
38               # echo 1 > /sys/kernel/debug/tracing/events/nvme/enable
39
40       •   Then look for NVMe Fabrics command (0x7f) at trace
41
42               /sys/kernel/debug/tracing/trace
