SYNOPSIS

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

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 <format> +
+
+--output-format=<format> +
+
+

+ Set the reporting format to normal, json, or + binary. Only one output format can be used at a time. +

+
+
+
+
+
+

EXAMPLES

+
+
    +
  • +

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

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

    +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
    +
    +
    • +
  • +

    +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.
