.SH "NAME"
nvme-wdc-get-pfail-dump \- Retrieve WDC device\*(Aqs pfail crash dump\&.
.SH "SYNOPSIS"
.sp
.nf
\fInvme wdc get\-pfail\-dump\fR <device> [\-\-output\-file=<FILE>, \-o <FILE>]
.fi
.SH "DESCRIPTION"
.sp
For the NVMe device given, sends the WDC vendor unique pfail crash dump request and saves the result to file\&. In current implementation pfail crash dump is captured if it is present\&. On success it will save the dump in file with appropriate suffix\&. Note that this command will clear the available dump from the device on success\&.
.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 "pfail_dump" suffix
