NVME-WDC-GET-PFAI(1)              NVMe Manual             NVME-WDC-GET-PFAI(1)

NAME
       nvme-wdc-get-pfail-dump - Retrieve WDC device's pfail crash dump.

SYNOPSIS
       nvme wdc get-pfail-dump <device> [--output-file=<FILE>, -o <FILE>]

DESCRIPTION
       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.

OPTIONS
       -o <FILE>, --output-file=<FILE>
           Output file; defaults to device serial number followed by
           "pfail_dump" suffix

EXAMPLES
       o   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

       o   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

       o   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
