You need to look at the host controller, host adapter, or host bus adapter (HBA) and HD support (kernel) before looking at disks, in my view. First, get an understanding of your system hardware / controllers.

Quote:
In computer hardware, a host controller, host adapter, or host bus adapter (HBA) connects a computer, which acts as the host system, to other network and storage devices. The terms are primarily used to refer to devices for connecting SCSI, Fibre Channel and SATA devices. Devices for connecting to IDE, Ethernet, FireWire, USB and other systems may also be called host adapters. Host adapters can be integrated in the motherboard or be on a separate expansion card.

What is the host adapter on your motherboard, exactly?

NAME

       qlc - ISP2200, ISP2300, and SP212 Family Fibre Channel host bus adapter driver.

SYNOPSIS

       SUNW,qlc

       The qlc host bus adapter driver is a Sun Fibre Channel transport  layer-compliant  nexus driver for the Qlogic ISP2200, ISP2200A,  ISP2310,
       ISP2312, and SP212 adapters. These adapters support  Fibre Channel SCSI and  IP Protocols, FC-AL public loop profile, point-to-point   fab-
       ric connection and Fibre  Channel service classes two and three (see NOTES section below).

       The  qlc driver interfaces with the Sun Fibre Channel transport	layer to support the standard functions provided by the SCSA interface. It
       supports auto request sense and tagged  queueing by default. The driver requires that all devices have unique  hard  addresses  in  private
       loop configurations. Devices with conflicting hard addresses are not accessible.

NOTES

	SP-212-based  host bus adapters (including QLA-210) are supported on x86 platforms only and are limited to a maximum of 8  targets in fab-
       ric and sixteen targets in local loop topology. FL topology is not supported with the SP-212-based host bus adapter.
