# nvme-toshiba-vs-internal-log(1)

Retrieve a Toshiba device's vendor specific internal log and either save to file or dump the contents.

## NAME

nvme-toshiba-vs-internal-log - Retrieve a Toshiba device's vendor specific internal log and either save to file or dump the contents.

## SYNOPSIS

```
nvme [<global-options>] toshiba vs-internal-log <device>
                        [--output-file=<FILE>, -O <FILE>] (optional)
                        [--saved-log, -s] (optional)
```

## DESCRIPTION

For the NVMe device given, sends the Toshiba internal device log request and either saves the result to a file or dumps the content to stdout.

The \<device\> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).

The log is associated with the controller rather than any namespaces.

Two logs exist, the current log and the previous log.

This will only work on Toshiba devices supporting this feature.

Note: The logs are quite large - typically 100’s of MB. This command can take several minutes to complete. A progress runner is included when data is written to file and a page count is included in the stdout dump.

## OPTIONS

- \-O \<FILE\>, --output-file=\<FILE\>

  Output binary file. Defaults to text-formatted dump to stdout

- \-p, --prev-log

  Use previous log contents. Defaults to the current log contents.

## 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

• Get the current log from the device and dump it to stdout:

```
# nvme toshiba internal-log /dev/nvme0
```

• Get the previous log from the device and save to a binary file:

```
# nvme toshiba internal-log /dev/nvme0 --output-file=log.bin --prev-log
```
