SYNOPSIS

nvme [<global-options>] boot-part-log <device> [--lsp=<field> | -s <field>]
                        [--output-file=<file> | -f <file>]

DESCRIPTION

Retrieves an Boot Partition log page from an NVMe device and provides the returned structure.

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

On success, the returned log structure will be in raw binary format only with --output-file option which is mandatory.

OPTIONS

-s <field>
--lsp=<field>

The log specified field of LID.

-f <file>
--output-file=<file>

File name to which raw binary data will be saved to.

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.

--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.
