nvme-fdp-feature1

Usage

Overview

For the NVMe device given, configure and manage the Flexible Data Placement (FDP) feature.

This command can be used to either show the current FDP feature configuration or change it.

 If no `--enable-conf-idx` or `--disable` options are provided, the current configuration is
displayed.

If the --enable-conf-idx or --disable options are provided, configuration is changed accordingly. Device may refuse the change if there is a namespace.

The <device> parameter is mandatory and must be a NVMe character device (ex: /dev/nvme0)

Options

-e <NUM>, --endgrp-id=<NUM>

Specify the endurance group ID. This option is mandatory if device supports endurance groups.

-c <NUM>, --enable-conf-idx=<NUM>

Enable FDP feature with the specified configuration. The configuration index matches position listed by nvme-fdp-config(1).

-d, --disable

Disable the current FDP feature configuration.

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. Other versions are rejected.

--quiet

Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level.

--set-options=<key=value>[,<key=value>...]

Set libnvme library options for this invocation. Supported keys are force-4k, mi-probe-enabled, test-base-dir and test-sysfs-dir.

--timeout=<ms>

Set the timeout for the command in milliseconds. infinite or -1 waits without a time limit (0xffffffff).

-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.
