NAME

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

SYNOPSIS

nvme device-self-test <device> [--namespace-id=<NUM> | -n <NUM>]
                        [--self-test-code=<NUM> | -s <NUM>] [--wait | -w]
                        [--output-format=<fmt> | -o <fmt>] [--verbose | -v]

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.

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.

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

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

-v, --verbose

Increase the information detail in the output.

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
