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
