SYNOPSIS

nvme [<global-options>] ocp get-error-injection <device> [--no-uuid | -n]
                        [--sel=<select> | -s <select>] [--all-ns | -a]

DESCRIPTION

Return set of error injection.

The <device> parameter is mandatory NVMe character device (ex: /dev/nvme0).

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.

-n
--no-uuid

Do not try to automatically detect UUID index for this command (required for old OCP 1.0 support)

-a
--all-ns

Send the command to all namespaces. This option is used to specify whether to target all namespaces or no specific namespace. This option is required for OCP 2.0 only devices, optional for OCP 2.5.

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. 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.

EXAMPLES

  • Has the program issue a get-error-injection to retrieve the 0xC0 get features.
