NVME-GET-PROPERTY(1) | NVMe Manual | NVME-GET-PROPERTY(1) |
NAME¶
nvme-get-property - Reads and shows the defined NVMe controller property for NVMe over Fabric
SYNOPSIS¶
nvme get-property <device> [--offset=<offset> | -o <offset>]
[--human-readable | -H ]
DESCRIPTION¶
Reads and shows the defined NVMe controller property for NVMe over Fabric.
OPTIONS¶
-o, --offset
The offset of the property. One of CAP=0x0, VS=0x8,
CC=0x14, CSTS=0x1c, NSSR=0x20
-H
--human-readable: Show the fields packed in the
property
EXAMPLES¶
•The following will run the get-property command
with offset 0
# nvme get-property /dev/nvme0 --offset=0x0 --human-readable
BUGS¶
Currently the CAP value is truncated to 32 bits due to a limitation in the ioctl interface.
In a recent enough kernel, the 64 bit value is shown in kernel traces.
•First enable traces by this command
# echo 1 > /sys/kernel/debug/tracing/events/nvme/enable
•Then look for NVMe Fabrics command (0x7f) at
trace
/sys/kernel/debug/tracing/trace
