SYNOPSIS

nvme [<global-options>] intel internal-log <device> [--log=<NUM>, -l <NUM>]
                [--region=<NUM>, r <NUM>]
                [--nlognum=<NUM>, m <NUM>]
                [--namespace-id=<NUM>, -n <NUM>]
                [--output-file=<FILE>, -O <FILE>]

DESCRIPTION

For the NVMe device given, sends the Intel vendor unique device log request and saves the result to a file.

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

This will only work on Intel devices supporting this feature which includes (but not limited to) all the Intel DC P3xxx family of controllers. Results for any other device are undefined.

OPTIONS

-l <NUM>
--log=<NUM>

Log type: 0, 1, or 2 for nlog, event log, and assert log, respectively.

-n <NUM>
--namespace-id=<NUM>

Namespace to use.

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

Output file; defaults to device name provided

-r <NUM>
--region=<NUM>

Select which core region to retrieve the log from. -1 for all available, if supported by the device.

-m <NUM>
--nlognum=<NUM>

When used with nlog, this specifies which nlog to read. -1 for all, if supported by the device.

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.

EXAMPLES

  • Gets the nlog from the device and saves to default file: 

    # nvme intel internal-log /dev/nvme0 --namespace-id=1 --log=0

  • Gets the event log from the device and saves to defined file: 

    # nvme intel internal-log /dev/nvme0 --namespace-id=1 --log=1 --output-file=MyAwesomeEventLog
