nvme wdc get-pfail-dump <device> [--output-file=<FILE>, -o <FILE>]
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.
The <device> parameter is mandatory NVMe character device (ex: /dev/nvme0).
This will only work on WDC devices supporting this feature. Results for any other device are undefined.
- -o <FILE>, --output-file=<FILE>
Output file; defaults to device serial number followed by "pfail_dump" suffix
Gets the pfail crash dump from the device and saves to default file in current directory (e.g. STM00019F3F9_pfail_dump.bin):
# nvme wdc get-pfail-dump /dev/nvme0
Gets the pfail crash dump from the device and saves to defined file in current directory (e.g. testSTM00019F3F9_pfail_dump.bin):
# nvme wdc get-pfail-dump /dev/nvme0 -o test
Gets the pfail crash dump from the device and saves to defined file with pathname (e.g. /tmp/testSTM00019F3F9_pfail_dump.bin):
# nvme wdc get-pfail-dump /dev/nvme0 -o /tmp/test
