NVME-TOSHIBA-VS-I(1)

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.

--timeout=<ms>
    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). 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
