.SH "DESCRIPTION"
.sp
For the NVMe device given, retrieves OCP DSSD Power State\&. Passing \-\-all calls NVMe Get Feature three times, returning all three of the Current, Default, and Saved values\&.
.sp
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0) or block device (ex: /dev/nvme0n1)\&.
.sp
This will only work on OCP compliant devices supporting this feature\&. Results for any other device are undefined\&.
.sp
On success it returns 0, error code otherwise\&.
.SH "OPTIONS"
