NAME

nvme-device-self-test - Perform the necessary tests to observe the performance and the parameters

SYNOPSIS

nvme [<global-options>] device-self-test <device>


                        [--namespace-id=<NUM> | -n <NUM>]


                        [--self-test-code=<NUM> | -s <NUM>]


                        [--wait | -w]

DESCRIPTION

Initiates the required test based on the user input.

The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).

On success, the corresponding test is initiated.

The results of this test can be queried via nvme self-test-log <device>.

OPTIONS

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

Indicate the namespace in which the device self-test has to be carried out

-s <NUM>, --self-test-code=<NUM>

This field specifies the action taken by the device self-test command : 0h: Show current state of device self-test operation 1h: Start a short device self-test operation 2h: Start a extended device self-test operation eh: Start a vendor specific device self-test operation fh: Abort the device self-test operation Default is 0h.

-w, --wait

Wait for the device self test to complete before exiting The device self-test is aborted by SIGINT signal interrupt for the wait The option is ignored if the abort self-test code option specified.

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

•Start a short device self-test in the namespace-id 1: 

# nvme device-self-test /dev/nvme0 -n 1 -s 1

•Abort the device self-test operation in the namespace-id 1: 

# nvme device-self-test /dev/nvme0 -n 1 -s 0xf
