I have SATA Raid controller based on 3112 chip.
I configured it in BIOS as stripe. Boot NetBSD.
dmesg shows me the following.

  satalink0 at pci0 dev 8 function 0
  satalink0: Silicon Image SATALink 3112 (rev. 0x02)
  satalink0: SATALink BA5 register space disabled
  satalink0: bus-master DMA support present
  satalink0: primary channel wired to native-PCI mode
  satalink0: using irq 5 for native-PCI interrupt
  atabus2 at satalink0 channel 0
  satalink0: secondary channel wired to native-PCI mode
  atabus3 at satalink0 channel 1
  satalink0: port 0: device present, speed: 1.5Gb/s
  satalink0: port 1: device present, speed: 1.5Gb/s

  wd2(satalink0:0:0): using PIO mode 4, Ultra-DMA mode 6 (Ultra/133) (using DMA)
  wd3(satalink0:1:0): using PIO mode 4, Ultra-DMA mode 6 (Ultra/133) (using DMA)

  wd2 at atabus2 drive 0: <ST3320620AS>

  wd2: drive supports 16-sector PIO transfers, LBA48 addressing
  wd2: 298 GB, 620181 cyl, 16 head, 63 sec, 512 bytes/sect x 625142448 sectors
  wd2: 32-bit data port
  wd2: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133)
  wd2(satalink0:0:0): using PIO mode 4, Ultra-DMA mode 6 (Ultra/133) (using DMA)

  wd3 at atabus3 drive 0: <ST3320620AS>
  wd3: quirks 2<FORCE_LBA48>
  wd3: drive supports 16-sector PIO transfers, LBA48 addressing
  wd3: 298 GB, 620181 cyl, 16 head, 63 sec, 512 bytes/sect x 625142448 sectors
  wd3: 32-bit data port
  wd3: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133)
  wd3(satalink0:1:0): using PIO mode 4, Ultra-DMA mode 6 (Ultra/133) (using DMA)

Now I want to run

  disklabel -e /dev/<WHAT_DEVICE_HERE?>

The only message about raid from dmesg is

  "Kernelized RAIDframe activated"

What devices are associated with raid arrays (semi-hardware?)
in NetBSD?
