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 hu- man-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 * 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.
