nvme-ocp-get-idle-wakeup-time - Define and print idle-wakeup-time value

nvme [<global-options>] ocp get-idle-wakeup-time <device>
                        [--sel=<select> | -s <select>]
                        [--namespace-id=<nsid> | -n <namespace-id>]

Define get-idle-wakeup-time. No argument prints current mode.

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:

-n <namespace-id>, --namespace-id=<namespace-id>

namespace-id (namespace-id): 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

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.
