[olug] ata8 identification

[Dan Linder]

What does "lshw" report?  When I run mine and I search for "ata4" (one of my
HDDs) I get this:
=== begin ===
  P: /devices/pci0000:00/*0000:00:11.0*/ata4/ata_port/ata4
  E: UDEV_LOG=3
  E: DEVPATH=/devices/pci0000:00/0000:00:11.0/ata4/ata_port/ata4
  E: SUBSYSTEM=ata_port
=== end ===

Later, looking for other "0000:00:11.0" strings I get this:
=== begin ===
>> block.5.1: /dev/sr0 cache
  scsi cache: 0x00
  block: name = *sda*, path = /class/block/sda
    dev = 8:0
    range = 16
    block device: bus = scsi, bus_id = 2:0:0:0 driver = sd
      path = /devices/pci0000:00/*0000:00:11.0*/host2/target2:0:0/2:0:0:0
    vendor = ATA
    model = WDC WD1501FASS-0
    rev = 05.0
    type = 0
=== end ===

Which matches with my /dev/sda being that drive.

Does that help any?
