# nvme-get-property(1)

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

## NAME

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

## SYNOPSIS

```
nvme [<global-options>] get-property <device>
                        [--offset=<offset> | -O <offset>]
```

## DESCRIPTION

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

## OPTIONS

- \-O \<offset\>, --offset=\<offset\>

  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

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 \<fmt\>, --output-format=\<fmt\>

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

- \--output-format-version=\<version\>

  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=\<key=value\>\[,\<key=value\>...\]

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

- \--timeout=\<ms\>

  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)](/nvme-cli.conf/5.md). A command-line flag always overrides the file.

## EXAMPLES

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

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

## 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
```
