.SH "NAME"
nvme-wdc-vs-error-reason-identifier \- Retrieve WDC device\*(Aqs telemetry log error reason identifier field
.SH "SYNOPSIS"

\fInvme wdc vs\-error\-reason\-identifier\fR <device> [\-\-log\-id=<NUM>, \-i <NUM>] [\-\-file=<FILE>, \-o <FILE>]
.fi
.SH "DESCRIPTION"
.sp
For the NVMe device given, retrieve the telemetry log error reason id field for either the host generated or controller initiated log\&. The controller initiated telemetry log page option must be enabled to retrieve the error reason id for that log page id\&.
.sp
The <device> parameter is mandatory and must be the NVMe character device (ex: /dev/nvme0)\&.
.sp
This will only work on WDC devices supporting this feature\&. Results for any other device are undefined\&.
.sp
On success it returns 0, error code otherwise\&.
.SH "OPTIONS"
.PP
\-i <id>, \-\-log\-id=<id>
.RS 4
Specifies the telemetry log id of the error reason identifier to retrieve\&. Use id 7 for the host generated log page\&. Use id 8 for the controller initiated log page\&. The default is 7/host generated
.RE
.PP
\-o <FILE>, \-\-output\-file=<FILE>
.RS 4
Output file; defaults to "<device serial number>_error_reason_identifier_host_<date>_<time>\&.bin" for the host generated log or "<device serial number>_error_reason_identifier_ctlr_<date>_<time>\&.bin" for the controller initiated log\&.
