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>]

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

EXAMPLES

       •   Print the namespaces present for zoned command set in JSON format

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

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

               # nvme list-ns /dev/nvme0
