GET-DSSD-POWER-ST(1) NVMe Manual GET-DSSD-POWER-ST(1)

NAME

nvme-ocp-get-dssd-power-state-feature - Get DSSD Power State

SYNOPSIS

nvme [<global-options>] 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, --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)

GLOBAL OPTIONS

The following options are defined at the top-level nvme command and are available to this subcommand:

--dry-run

Print the command that would be executed, but do not actually execute it.

--no-ioctl-probing

Disable probing for 64-bit IOCTL support.

--no-retries

Disable retry logic on transient errors.

-o <fmt>, --output-format=<fmt>

Set the reporting format to normal, tabular, 'json, or binary. Only one output format may be used at a time.

--output-format-version=<version>

Select the output format version. Version 1 uses the original field naming, while version 2 (default) provides more consistent and script-friendly field names.

--timeout=<ms>

Set the timeout for the command in milliseconds.

-v, --verbose

Increase the level of detail in the output. May be specified multiple times to further increase verbosity.

These options can also be set as machine-wide defaults in nvme-cli.conf(5). A command-line flag always overrides the file.

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
