NAME

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

SYNOPSIS

nvme [<global-options>] cmdset-ind-id-ns <device>


                        [--namespace-id=<nsid> | -n <nsid>]


                        [--raw-binary | -b]

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.

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

•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.
