NAME¶
nvme-ns-descs - Send NVMe Identify for a list of Namespace Identification Descriptor structure, return result and structure
SYNOPSIS¶
nvme ns-descs <device> [--namespace-id=<nsid> | -n <nsid>] [--raw-binary | -b]
[--output-format=<fmt> | -o <fmt>] [--verbose | -v]
DESCRIPTION¶
For the NVMe device given, sends an identify for a list of namespace identification descriptor structures 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>
-b, --raw-binary
-o <fmt>, --output-format=<fmt>
-v, --verbose
EXAMPLES¶
# nvme ns-descs /dev/nvme0 -n 1 # nvme ns-descs /dev/nvme0n1 -n 2 # nvme ns-descs /dev/nvme0 --namespace-id=1
# nvme ns-descs /dev/nvme0n1 --raw-binary > ns_descs.raw # nvme ns-descs /dev/nvme0n1 -b > ns_descs.raw
It is probably a bad idea to not redirect stdout when using this mode.
