nvme-ocp-get-dssd-power-state-feature - Man Page

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:

Select	Description
0	Current
1	Default
2	Saved
3	Supported capabilities
4-7	Reserved

-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)
