'nvme toshiba vs-internal-log ' <device>
                [--output-file=<FILE>, -o <FILE>] (optional)
                [--saved-log, -s] (optional)

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​.

-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​.

• 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
