NAME
       nvme-log-boot-part - Retrieves a Boot Partition log page from an NVMe
       device

SYNOPSIS
       nvme [<global-options>] log boot-part <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.

       --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
       o   Retrieve Boot Partition data to boot_part_log.bin

               # nvme log boot-part /dev/nvme0 --output-file=boot_part_log.bin
