NAME

aac —

Adaptec AdvancedRAID Controller driver

SYNOPSIS

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"

DESCRIPTION

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.

DIAGNOSTICS

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.

HISTORY

The aac driver first appeared in FreeBSD 4.3.

BUGS

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.
