AAC(4)		       FreeBSD Kernel Interfaces Manual			AAC(4)

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 ver-
     sions 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.

   Tuning
     The read-only sysctl hw.aac.iosize_max defaults to	65536 and may be set
     at	boot time to another value via loader(8).  This	value determines the
     maximum data transfer size	allowed	to/from	an array.  Setting it higher
     will result in better performance,	especially for large sequential	access
     patterns.	Beware:	internal limitations of	the card limit this value to
     64K for arrays with many members.	While it may be	safe to	raise this
     value, this is done at the	operator's own risk.  Note also	that perfor-
     mance peaks at a value of 96K, and	drops off dramatically at 128K,	due to
     other limitations of 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.
