nvme-log-boot-part(1)

SYNOPSIS

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

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.

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. Other versions are rejected.
--quiet: Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level.
--set-options=<key=value>[,<key=value>…]: Set libnvme library options for this invocation. Supported keys are force-4k, mi-probe-enabled, test-base-dir and test-sysfs-dir.
--timeout=<ms>: Set the timeout for the command in milliseconds. infinite or -1 waits without a time limit (0xffffffff).
-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.
