# [NAME](#NAME)

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

# [SYNOPSIS](#SYNOPSIS)

```
nvme [<global-options>] get-property <device>


                        [--offset=<offset> | -O <offset>]
```

# [DESCRIPTION](#DESCRIPTION)

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

# [OPTIONS](#OPTIONS)

-O &lt;offset&gt;, --offset=&lt;offset&gt;

The offset of the property, or the name of a register, e.g. 0x14 or cc. The properties of a fabrics controller are cap (0x0), vs (0x8), cc (0x14), csts (0x1c), nssr (0x20), nssd (0x64) and crto (0x68), the transport may define more.

# [GLOBAL OPTIONS](#GLOBAL_OPTIONS)

The following options are defined at the top-level nvme command and are available to this subcommand:

--dry-run

Print the command that would be executed, but do not actually execute it.

--no-ioctl-probing

Disable probing for 64-bit IOCTL support.

--no-retries

Disable retry logic on transient errors.

-o &lt;fmt&gt;, --output-format=&lt;fmt&gt;

Set the reporting format to *normal*, *tabular, 'json*, or *binary*. Only one output format may be used at a time.

--output-format-version=&lt;version&gt;

Select the output format version. Version *1* uses the original field naming, while version *2* (default) provides more consistent and script-friendly field names. Other versions are rejected.

--quiet

Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level.

--set-options=&lt;key=value&gt;\[,&lt;key=value&gt;...]

Set libnvme library options for this invocation. Supported keys are *force-4k*, *mi-probe-enabled*, *test-base-dir* and *test-sysfs-dir*.

--timeout=&lt;ms&gt;

Set the timeout for the command in milliseconds. *infinite* or *-1* waits without a time limit (0xffffffff).

-v, --verbose

Increase the level of detail in the output. May be specified multiple times to further increase verbosity.

These options can also be set as machine-wide defaults in [nvme-cli.conf(5)](/man/os/nvme-cli/nvme-cli.conf.5). A command-line flag always overrides the file.

# [EXAMPLES](#EXAMPLES)

•The following will run the get-property command with offset 0

```
# nvme get-property /dev/nvme0 --offset=0x0 --verbose
```

# [BUGS](#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
```
