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] [--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 NVME Part of the nvme-user suite NVMe 10/31/2024 NVME-GET-PROPERTY(1)
