nvme-cmdset-ind-id-ns - Send NVMe I/O Command Set Independent Identify Namespace, return result and structure.
nvme cmdset-ind-id-ns <device> [--namespace-id=<nsid> | -n <nsid>]
[-b | --raw-binary]
[--human-readable | -H]
[--output-format=<fmt> | -o <fmt>]
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.
-n <nsid>, --namespace-id=<nsid>
-b, --raw-binary
-H, --human-readable
-o <format>, --output-format=<format>
# nvme cmdset-ind-id-ns /dev/nvme0n1
# 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
# 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.
