NVME-WDC-CAP-DIAG(1)		   NVMe Manual		    NVME-WDC-CAP-DIAG(1)

NAME
     nvme-wdc-cap-diag - Retrieve WDC device's diagnostic log and save to file.

SYNOPSIS
     nvme wdc cap-diag <device> [--output-file=<FILE>, -o <FILE>] [--transfer-size=<SIZE>, -s <SIZE>]

DESCRIPTION
     For  the NVMe device given, sends the WDC Vendor Unique Capture-Diagnostics
     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  "cap_diag"
	 suffix

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

EXAMPLES
     *	 Gets  the  capture diagnostics log from the device and saves to default
	 file in current directory (e.g. STM00019F3F9cap_diag.bin):

	     # nvme wdc cap-diag /dev/nvme0

     *	 Gets the capture diagnostics log from the device and saves  to  defined
	 file in current directory (e.g. testSTM00019F3F9cap_diag.bin):

	     # nvme wdc cap-diag /dev/nvme0 -o test

     *	 Gets  the  capture diagnostics log from the device and saves to defined
	 file with pathname (e.g. /tmp/testSTM00019F3F9cap_diag.bin):

	     # nvme wdc cap-diag /dev/nvme0 -o /tmp/test

     *	 Gets the capture diagnostics log from the device transferring the  data
	 in  64k  chunks  and  saves  to default file in current directory (e.g.
	 STM00019F3F9internal_fw_log.bin):

	     # nvme wdc cap-diag /dev/nvme0 -s 0x10000

     *	 Gets the capture diagnostics log from the device transferring the  data
	 in  16k  chunks  and  saves  to default file in current directory (e.g.
	 STM00019F3F9internal_fw_log.bin):

	     # nvme wdc cap-diag /dev/nvme0 -s 16384
