# [NAME](#NAME)

nvme-ocp-hardware-component-log - retrieve hardware component log

# [SYNOPSIS](#SYNOPSIS)

```
nvme [<global-options>] ocp hardware-component-log <device>


                        [--comp-id=<num> | -i <num>]


                        [--list | -l]
```

# [DESCRIPTION](#DESCRIPTION)

Retrieve hardware component log.

The &lt;device&gt; parameter is mandatory NVMe character device (ex: /dev/nvme0).

This will only work on OCP compliant devices supporting this feature. Results for any other device are undefined.

On success it returns 0, error code otherwise.

# [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.

--timeout=&lt;ms&gt;

Set the timeout for the command in milliseconds.

-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)

•Has the program issue a ocp hardware-component-log

```
# nvme ocp hardware-component-log /dev/nvme0
```

•Has the program issue a ocp hardware-component-log with asic component list

```
# nvme ocp hardware-component-log /dev/nvme0 -i asic -l
```

# [NVME](#NVME)

Part of the nvme-user suite.
