# nvme-ocp-hardware-component-log(1)

retrieve hardware component log

## NAME

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

## SYNOPSIS

```
nvme [<global-options>] ocp hardware-component-log <device>
                        [--comp-id=<num> | -i <num>]
                        [--list | -l]
```

## DESCRIPTION

Retrieve hardware component log.

The \<device\> 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.

## OPTIONS

- \-i \<num\>, --comp-id=\<num\>

## 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

• 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
```
