31 .Nd Adaptec AdvancedRAID Controller driver
33 To compile this driver into the kernel,
34 place the following lines in your
35 kernel configuration file:
36 .Bd -ragged -offset indent
41 To compile in debugging code:
42 .Cd options AAC_DEBUG=N
45 Alternatively, to load the driver as a
46 module at boot time, place the following line in
48 .Bd -literal -offset indent
54 driver provides support for the Adaptec AAC family of SCSI Ultra2, Ultra160,
55 and Ultra320, SATA and SAS RAID controllers.
57 Access to RAID containers is available via the
62 device enables the SCSI pass-thru interface and allows devices connected
63 to the card such as CD-ROMs to be available via the CAM
66 Note that not all cards allow this interface to be enabled.
70 device nodes provide access to the management interface of the controller.
71 One node exists per installed card.
76 exist for compatibilty with the Dell and HP versions of management tools,
78 If the kernel is compiled with the
84 modules are loaded, the
87 interface for the management device will be enabled and will allow
88 Linux-based management applications to control the card.
92 defaults to 65536 and may be set at boot time to another value via
94 This value determines the maximum data transfer size allowed
96 Setting it higher will result in better performance,
97 especially for large sequential access patterns.
100 of the card limit this value to 64K for arrays with many members.
101 While it may be safe to raise this value, this is done
102 .Em at the operator's own risk .
104 performance peaks at a value of 96K,
105 and drops off dramatically at 128K,
106 due to other limitations of the card.

213 will enable increasingly verbose debug messages.
215 The adapter can send status and alert messages asynchronously
217 These messages are printed on the system console,
218 and are also queued for retrieval by a management application.
229 driver first appeared in
233 .Aq msmith@FreeBSD.org
235 .Aq scottl@FreeBSD.org
237 This driver is not compatible with Dell controllers that have version 1.x
239 The firmware version is the same as the kernel version printed in the BIOS
240 POST and driver attach messages.
242 The controller is not actually paused on suspend/resume.
