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>

attributes to return in the provided data:
| Select | Description |

-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)
