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 return in the provided data:

   -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

      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

      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
