NAME
       nvme-id-ns-list - Send NVMe Identify List Namespaces, return result and
       structure

SYNOPSIS
       nvme [<global-options>] id ns-list <device> [--namespace-id=<nsid> | -n <nsid>]
                               [--csi=<command_set_identifier> | -y
                               <command_set_identifier>]
                               [--all | -a]

DESCRIPTION
       For the NVMe device given, sends an identify command for namespace list
       and provides the result and 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). If the starting namespace in the list always begins with
       0 unless the '--namespace-id' option is given to override.

       On success, the namespace array is printed for each index and nsid for
       a valid nsid.

OPTIONS
       -n <nsid>, --namespace-id=<nsid>
           Retrieve the identify list structure starting with the given nsid.

       -y <command_set_identifier>, --csi=<command_set_identifier>
           If this value is given, retrieve the identify list structure
           associated with the specified I/O command set.

       -a, --all
           Retrieve the identify list structure for all namespaces in the
           subsystem, whether attached or inactive.

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   Print the namespaces present for zoned command set in JSON format

               # nvme id ns-list /dev/nvme0 -y 2 -a -o json

       o   Print the namespaces present for NVM Command Set in normal format

               # nvme id ns-list /dev/nvme0
