These machines have a Mylex DAC960 raid adapter in a pci slot. They also have two onboard Adaptec controllers (alad). If you are not using the Adaptec controllers then disable them in the CMOS. If you are using them (for tape or cd) then you can add the scsi.noscan option to the boot string.

aacraid
AACRAID(4) BSD Kernel Interfaces Manual AACRAID(4)
NAME
aacraid -- Adaptec AACRAID Controller driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device pci
device aacraid
To compile in debugging code:
options AACRAID_DEBUG=N
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
aacraid_load="YES"
DESCRIPTION
The aacraid driver provides support for the Adaptec by PMC RAID controllers, including Series 6/7/8 and upcoming families.
The RAID containers are handled via the aacraidp0 bus. The physical buses are represented by the aacraidp? devices (beginning with
aacraidp1). These devices enable the SCSI pass-thru interface and allows devices connected to the card such as CD-ROMs to be available via
the CAM scsi(4) subsystem. Note that not all cards allow this interface to be enabled.
The /dev/aacraid? device nodes provide access to the management interface of the controller. One node exists per installed card. If the
kernel is compiled with the COMPAT_LINUX option, or the aacraid_linux.ko and linux.ko modules are loaded, the Linux-compatible ioctl(2)
interface for the management device will be enabled and will allow Linux-based management applications to control the card.
HARDWARE
Controllers supported by the aacraid driver include:
o Adaptec ASR-6405(T|E)
o Adaptec ASR-6445
o Adaptec ASR-6805(T|E|Q|TQ)
o Adaptec ASR-7085
o Adaptec ASR-7805(Q)
o Adaptec ASR-70165
o Adaptec ASR-71605(E|Q)
o Adaptec ASR-71685
o Adaptec ASR-72405
o Adaptec Series 8 cards
FILES
/dev/aacraid? aacraid management interface
DIAGNOSTICS
Compiling with AACRAID_DEBUG set to a number between 0 and 3 will enable increasingly verbose debug messages.
The adapter can send status and alert messages asynchronously to the driver. These messages are printed on the system console, and are also
queued for retrieval by a management application.
