SYNOPSIS

nvme ocp get-dssd-power-state-feature <device>
                        [--sel=<select> | -S <select>] [--all | -a]
                        [--no-uuid | -n]

DESCRIPTION

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.

The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0) or block device (ex: /dev/nvme0n1).

This will only work on OCP compliant devices supporting this feature. Results for any other device are undefined.

On success it returns 0, error code otherwise.
