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, ā--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
