It seems the driver doesn't implement that, I can see it for the 
ICH10R-controller, but not for the SiL-based one this drive is on:

It would look like ata14 is the equivalent of scsi13 then - lsscsi or
"cat /proc/scsi" should show you the drives connected on controller 13
(or look in /sys/class/scsi_disk/13*/device/block).
