.SH "NAME"
nvme-device-self-test \- Perform the necessary tests to observe the performance and the parameters
.SH "SYNOPSIS"

\fInvme\fR [<global\-options>] \fIdevice\-self\-test\fR <device>
                        [\-\-namespace\-id=<NUM> | \-n <NUM>]

.SH "DESCRIPTION"
.sp
Initiates the required test based on the user input\&.
.sp
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
.sp
On success, the corresponding test is initiated\&.
.sp
The results of this test can be queried via \fInvme self\-test\-log <device>\fR\&.
.SH "OPTIONS"
.PP
\-n <NUM>, \-\-namespace\-id=<NUM>
.RS 4
Indicate the namespace in which the device self\-test has to be carried out The broadcast value 0xffffffff can also be given as
\fIall\fR
or
\fI\-1\fR\&.
.RE
.PP
\-s <NUM>, \-\-self\-test\-code=<NUM>
.RS 4
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\&.
.RE
.PP
\-w, \-\-wait
.RS 4
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\&.
.RE
.SH "GLOBAL OPTIONS"
.sp
The following options are defined at the top\-level nvme command and are available to this subcommand:
.PP
\-\-dry\-run
.RS 4
Print the command that would be executed, but do not actually execute it\&.
.RE
.PP
\-\-no\-ioctl\-probing
.RS 4
Disable probing for 64\-bit IOCTL support\&.
.RE
.PP
\-\-no\-retries
.RS 4
Disable retry logic on transient errors\&.
.RE
.PP
\-o <fmt>, \-\-output\-format=<fmt>
.RS 4
Set the reporting format to
\fInormal\fR,
\fItabular, \*(Aqjson\fR, or
\fIbinary\fR\&. Only one output format may be used at a time\&.
.RE
.PP
\-\-output\-format\-version=<version>
.RS 4
Select the output format version\&. Version
\fI1\fR
uses the original field naming, while version
\fI2\fR
(default) provides more consistent and script\-friendly field names\&. Other versions are rejected\&.
.RE
.PP
\-\-quiet
.RS 4
Suppress informational messages\&. Errors are still reported, and \-\-quiet cancels any \-\-verbose for the library log level\&.
.RE
.PP
\-\-set\-options=<key=value>[,<key=value>\&...]
.RS 4
Set libnvme library options for this invocation\&. Supported keys are
\fIforce\-4k\fR,
\fImi\-probe\-enabled\fR,
\fItest\-base\-dir\fR
and
\fItest\-sysfs\-dir\fR\&.
.RE
.PP
\-\-timeout=<ms>
.RS 4
Set the timeout for the command in milliseconds\&.
\fIinfinite\fR
or
\fI\-1\fR
waits without a time limit (0xffffffff)\&.
.RE
.PP
\-v, \-\-verbose
.RS 4
Increase the level of detail in the output\&. May be specified multiple times to further increase verbosity\&.
.RE
.sp
These options can also be set as machine\-wide defaults in nvme\-cli\&.conf(5)\&. A command\-line flag always overrides the file\&.
.SH "EXAMPLES"
.sp

.ie n \{\
