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]
[--timeout=<timeout> | -t <timeout>]
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.
-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.
-t <timeout>, --timeout=<timeout>
Override default timeout value. In milliseconds.
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
