NVME-NS-GET-ID(1)                 NVMe Manual                NVME-NS-GET-ID(1)

NAME
       nvme-ns-get-id - Retrieves the namespace ID for an NVMe block device

SYNOPSIS
       nvme [<global-options>] ns get-id <device>

DESCRIPTION
       Retrieves the namespace ID for an NVMe block device. The <device> param
       is mandatory and must be an NVMe block device (ex: /dev/nvme0n1).

OPTIONS
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   Shows the namespace id for the given block device:

               # nvme ns get-id /dev/nvme0n1
