nvme-wdc-get-pfail-dump - Man Page

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
