.SH "DESCRIPTION"
.sp
For the NVMe device given, sends a Sanitize command and provides the result\&.
.sp
The <device> parameter is mandatory NVMe character device (ex: /dev/nvme0)\&.
.sp
On success it returns 0, error code otherwise\&.
.SH "OPTIONS"
.PP
\-d, \-\-no\-dealloc
.RS 4
No Deallocate After Sanitize: If set, then the controller shall not deallocate any logical blocks as a result of successfully completing the sanitize operation\&. If cleared, then the controller should deallocate logical blocks as a result of successfully completing the sanitize operation\&. This bit shall be ignored if the Sanitize Action field is set to 001b (i\&.e\&., Exit Failure Mode)\&.
.RE

.RS 4
Overwrite Invert Pattern Between Passes: If set, then the Overwrite Pattern shall be inverted between passes\&. If cleared, then the overwrite pattern shall not be inverted between passes\&. This bit shall be ignored unless the Sanitize Action field is set to 011b (i\&.e\&., Overwrite)\&.
.RE
.PP
\-n <overwrite\-pass\-count>, \-\-owpass=<overwrite\-pass\-count>
.RS 4
Overwrite Pass Count: This field specifies the number of overwrite passes (i\&.e\&., how many times the media is to be overwritten) using the data from the Overwrite Pattern field of this command\&. A value of 0 specifies 16 overwrite passes\&. This field shall be ignored unless the Sanitize Action field is set to 011b (i\&.e\&., Overwrite)\&.
.RE
.PP
\-u, \-\-ause
.RS 4
Allow Unrestricted Sanitize Exit: If set, then the sanitize operation is performed in unrestricted completion mode\&. If cleared then the sanitize operation is performed in restricted completion mode\&. This bit shall be ignored if the Sanitize Action field is set to 001b (i\&.e\&., Exit Failure Mode)\&.
