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
