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