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
