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

       •   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
