nvme-nvm-id-ns(1) ================= NAME ---- nvme-nvm-id-ns - Send NVMe Identify NVM Command Set specific Namespace data structure, display structure SYNOPSIS -------- [verse] 'nvme nvm-id-ns' <device> [--uuid-index=<uuid-index> | -U <uuid_index>] [--namespace-id=<NUM> | -n <NUM>] [-v | --verbose] [--output-format=<fmt> | -o <fmt>] DESCRIPTION ----------- Identify NVM Command Set specific Namespace data structure for the specified NSID for the NVM Command Set specified in the CSI field. The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1). 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 <NUM>:: --namespace-id=<NUM>:: Use the provided namespace id for the command. If not provided, the namespace id of the block device will be used. If the command is issued to a non-block device, the parameter is required. -U <uuid-index>:: --uuid-index=<uuid-index>:: UUID Index of the feature -v:: --verbose:: Increase the information detail in the output. -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 nvm-id-ns /dev/nvme0n1 ------------ + * If using the character device or overriding namespace id: + ------------ # nvme nvm-id-ns /dev/nvme0 -n 1 # nvme nvm-id-ns /dev/nvme0n1 -n 1 # nvme nvm-id-ns /dev/nvme0 --namespace-id=1 ------------ + * Have the program return the raw structure in binary: + ------------ # nvme nvm-id-ns /dev/nvme0n1 -o binary > id_ns.raw # nvme nvm-id-ns /dev/nvme0n1 --output-format=binary > id_ns.raw ------------ + It is probably a bad idea to not redirect stdout when using this mode. * Alternatively you may want to send the data to another program that can parse the raw buffer. + ------------ NVME ---- Part of the nvme-user suite
