NAME
       nvme-ocp-get-dssd-power-state-feature - Get DSSD Power State

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.

OPTIONS
       -S <select>, --sel=<select>
           Select (SEL): This field specifies which value of the attributes to

           +-------+------------------------+

       -a, --all
           Print out all 3 values at once - Current DSSD Power State, Default
           DSSD Power State, and Saved DSSD Power State

       -n, --no-uuid
           Do not try to automatically detect UUID index for this command
           (required for old OCP 1.0 support)

EXAMPLES
       o   Has the program issue a get-dssd-power-state-feature command to get
           the Curent DSSD Power State in watts.

               # nvme ocp get-dssd-power-state-feature /dev/nvme0 -S 0

       o   Has the program issue a get-dssd-power-state-feature command to get
           all three DSSD Power States in watts.

               # nvme ocp get-dssd-power-state-feature /dev/nvme0 -a
