In current implementation 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 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 , \-\-output\-file= .RS 4 Output file; defaults to device serial number followed by "crash_dump" suffix .RE .SH "EXAMPLES" .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} Gets the crash dump from the device and saves to default file in current directory (e\&.g\&.
