.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\&.
.SH "OPTIONS"
.PP
\-n <NUM>, \-\-namespace\-id=<NUM>
.RS 4
Indicate the namespace in which the device self\-test has to be carried out
.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
.PP
\-o <fmt>, \-\-output\-format=<fmt>
.RS 4
Set the reporting format to
\fInormal\fR,
\fIjson\fR
or
\fIbinary\fR\&. Only one output format can be used at a time\&.
.RE
.PP
\-v, \-\-verbose
.RS 4
Increase the information detail in the output\&.
