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

SYNOPSIS
       nvme list-ns <device> [--namespace-id=<nsid> | -n <nsid>]
                               [--csi=<command_set_identifier> | -y <command_set_identifier>]
                               [--all | -a]
                               [--output-format=<fmt> | -o <fmt>] [--verbose | -v]

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.

       -o <fmt>, --output-format=<fmt>
           Set the reporting format to normal, json or binary. Only one output
           format can be used at a time.

       -v, --verbose
           Increase the information detail in the output.

EXAMPLES
       o   Print the namespaces present for zoned command set in JSON format

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

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

               # nvme list-ns /dev/nvme0
