nvme-set-feature - Sets an NVMe feature, returns applicable results
nvme set-feature <device> [--namespace-id=<nsid> | -n <nsid>]
[--feature-id=<fid> | -f <fid>] [--value=<value> | -v <value>]
[--uuid-index=<uuid-index> | -U <uuid_index>]
[--data-len=<data-len> | -l <data-len>]
[--data=<data-file> | -d <data-file>]
[--save| -s]
Submits an NVMe Set Feature admin command and returns the applicable results. This may be the feature’s value, or may also include a feature structure if the feature requires it (ex: LBA Range Type).
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 value sent to the device is displayed
-n <nsid>, --namespace-id=<nsid>
-f <fid>, --feature-id=<fid>
-l <data-len>, --data-len=<data-len>
-d <data-file>, --data=<data-file>
-v <value>, --value=<value>
-s, --save
-U <uuid-index>, --uuid-index=<uuid-index>
