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:
Select Description 0 Current 1 Default 2 Saved 3 Supported capabilities 4-7 Reserved - -a, ā--all
Print out all 3 values at once - Current DSSD Power State, Default DSSD Power State, and Saved DSSD Power State
- -n, ā--no-uuid
Do not try to automatically detect UUID index for this command (required for old OCP 1.0 support)
