NVME-CMDSET-IND-I(1)              NVMe Manual             NVME-CMDSET-IND-I(1)

NAME
       nvme-cmdset-ind-id-ns - Send NVMe I/O Command Set Independent Identify
       Namespace, return result and structure.

SYNOPSIS
       nvme cmdset-ind-id-ns <device> [--namespace-id=<nsid> | -n <nsid>]
                               [--raw-binary | -b] [--human-readable | -H]
                               [--output-format=<fmt> | -o <fmt>] [--verbose | -v]

DESCRIPTION
       For the NVMe device given, sends an I/O Command Set Independent
       identify namespace command 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 character device is given, the '--namespace-id'
       option is mandatory, otherwise it will use the ns-id of the namespace
       for the block device you opened. For block devices, the ns-id used can
       be overridden with the same option.

       On success, the structure may be returned in one of several ways
       depending on the option flags; the structure may be parsed by the
       program or the raw buffer may be printed to stdout.

OPTIONS
       -n <nsid>, --namespace-id=<nsid>
           Retrieve the identify namespace structure for the given nsid. This
           is required for the character devices, or overrides the block nsid
           if given.

       -b, --raw-binary
           Print the raw buffer to stdout. Structure is not parsed by program.
           This overrides the vendor specific and human readable options.

       -H, --human-readable
           This option will parse and format many of the bit fields into
           human-readable formats.

       -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   Has the program interpret the returned buffer and display the known
           fields in a human readable format:

               # nvme cmdset-ind-id-ns /dev/nvme0n1

       o   If using the character device or overriding namespace id:

               # nvme cmdset-ind-id-ns /dev/nvme0 -n 1
               # nvme cmdset-ind-id-ns /dev/nvme0n1 -n 1
               # nvme cmdset-ind-id-ns /dev/nvme0 --namespace-id=1

       o   Have the program return the raw structure in binary:

               # nvme cmdset-ind-id-ns /dev/nvme0n1 --raw-binary > id_ns.raw
               # nvme cmdset-ind-id-ns /dev/nvme0n1 -b > id_ns.raw

           It is probably a bad idea to not redirect stdout when using this
           mode.
