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]
                               [--output-format=<fmt> | -o <fmt>] [--verbose | -v]
                               [--timeout=<timeout> | -t <timeout>]

DESCRIPTION

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

OPTIONS

       -O <offset>, --offset=<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

       -o <fmt>, --output-format=<fmt>
           Set the reporting format to normal, json or binary. Only one output format can be used
           at a time.

       -v, --verbose
           Increase the information detail in the output.

       -t <timeout>, --timeout=<timeout>
           Override default timeout value. In milliseconds.

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
