aac — Adaptec
AdvancedRAID Controller driver
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device pci
device aac
device aacp
To compile in debugging code:
options AAC_DEBUG=N
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
aac_load="YES"
The aac driver provides support for the
Adaptec AAC family of SCSI Ultra2, Ultra160, and Ultra320, SATA and SAS RAID
controllers.
Access to RAID containers is available via the
/dev/aacd? device nodes. The
aacp device enables 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/aac? device nodes provide access
to the management interface of the controller. One node exists per installed
card. The aliases /dev/afa? and
/dev/hpn? exist for compatibility with the Dell and
HP versions of management tools, respectively. If the kernel is compiled
with the COMPAT_LINUX option, or the
aac_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.
Controllers supported by the aac driver
include:
Compiling with AAC_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.
The aac driver first appeared in
FreeBSD 4.3.

This driver is not compatible with Dell controllers that have version 1.x firmware. The firmware version is the same as the kernel version printed in the BIOS POST and driver attach messages.
The controller is not actually paused on suspend/resume.
