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>]
[−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.
