NAME

       nvme-wdc-vs-internal-log - Retrieve WDC device's internal firmware log and save to file.

SYNOPSIS

       nvme wdc vs-internal-log <device> [--output-file=<FILE>, -o <FILE>] [--transfer-size=<SIZE>, -s <SIZE>]

DESCRIPTION

       For the NVMe device given, sends the WDC Vendor Specific Internal Log request and saves
       the result to a file.

       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
           "internal_fw_log<date>_<time>.bin" suffix

       -s <SIZE>, --transfer-size=<SIZE>
           Transfer size; defaults to 0x10000 (65536 decimal) bytes

EXAMPLES

       •   Gets the internal firmware log from the device and saves to default file in current
           directory (e.g. STM00019F3F9_internal_fw_log_20171127_095704.bin):

               # nvme wdc vs-internal-log /dev/nvme0

       •   Gets the internal firmware log from the device and saves to defined file in current
           directory (e.g. test.bin):

               # nvme wdc vs-internal-log /dev/nvme0 -o test.bin

       •   Gets the internal firmware log from the device and saves to defined file with pathname
           (e.g. /tmp/test):

               # nvme wdc vs-internal-log /dev/nvme0 -o /tmp/test

       •   Gets the internal firmware log from the device transferring the data in 64k chunks and
           saves to default file in current directory (e.g.
           STM00019F3F9_internal_fw_log_20171127_100754.bin):

               # nvme wdc vs-internal-log /dev/nvme0 -s 0x10000

       •   Gets the internal firmware log from the device transferring the data in 16k chunks and
           saves to default file in current directory (e.g.
           STM00019F3F9_internal_fw_log_20171127_100950.bin):

               # nvme wdc vs-internal-log /dev/nvme0 -s 16384
