.SH "DESCRIPTION"
.sp
For the NVMe device given, sends the WDC Vendor Specific Internal Log request and saves the result to a file\&.
.sp
The <device> parameter is mandatory NVMe character device (ex: /dev/nvme0)\&.
.sp
This will only work on WDC devices supporting this feature\&. Results for any other device are undefined\&.
.SH "OPTIONS"
.PP
\-o <FILE>, \-\-output\-file=<FILE>
.RS 4
Output file; defaults to device serial number followed by "\fIinternal_fw_log\fR<date>_<time>\&.bin" suffix
.RE
.PP
\-s <SIZE>, \-\-transfer\-size=<SIZE>
.RS 4
Transfer size; defaults to 0x10000 (65536 decimal) bytes
.RE
.PP
\-d <DATA AREA>, \-\-data\-area=<DATA AREA>
.RS 4
DUI data area to retrieve\&. The DUI data areas from 1 to <DATA AREA> will be retrieved\&. This parameter is currently only supported on the SN340, SN640, SN730, and SN840 devices\&.
.RE
.PP
\-f <FILE SIZE>, \-\-file\-size=<FILE SIZE>
.RS 4
Specifies the desired size of the data file starting at the passed in offset\&. This allows the user to retrieve the data in several smaller files of the passed in size\&. This parameter is currently only supported on the SN340 device\&.
.RE
.PP
\-e <OFFSET>, \-\-offset=<OFFSET>
.RS 4
Specifies the data offset at which to start retrieving the data\&. This parameter is used in combination with the file size parameter to retrieve the data in several smaller files\&. This parameter is currently only supported on the SN340 device\&.
.RE
.PP
\-t <TYPE>, \-\-type=<TYPE>
.RS 4
Specifies the telemetry type \- NONE, HOST, or CONTROLLER\&. This parameter is used to get either the host generated or controller initiated telemetry log page\&. If not specified or none is specified, the command will return the default E6 log data\&. This parameter is currently only supported on the SN640 and SN840 devices\&.
.RE
.PP
\-v <VERBOSE>, \-\-verbose=<VERBOSE>
.RS 4
Provides additional debug messages for certain drives\&.
