28.Os
29.Sh NAME
30.Nm aac
31.Nd Adaptec AdvancedRAID Controller driver
32.Sh SYNOPSIS
33To compile this driver into the kernel,
34place the following lines in your
35kernel configuration file:
36.Bd -ragged -offset indent
37.Cd device pci
38.Cd device aac
39.Cd device aacp
40.Pp
41To compile in debugging code:
42.Cd options AAC_DEBUG=N
43.Ed
44.Pp
45Alternatively, to load the driver as a
46module at boot time, place the following line in
47.Xr loader.conf 5 :
48.Bd -literal -offset indent
49aac_load="YES"
50.Ed
51.Sh DESCRIPTION
52The
53.Nm
54driver provides support for the Adaptec AAC family of SCSI Ultra2, Ultra160,
55and Ultra320, SATA and SAS RAID controllers.
56.Pp
57Access to RAID containers is available via the
58.Pa /dev/aacd?
59device nodes.
60The
61.Nm aacp
62device enables the SCSI pass-thru interface and allows devices connected
63to the card such as CD-ROMs to be available via the CAM
64.Xr scsi 4
65subsystem.
66Note that not all cards allow this interface to be enabled.
67.Pp
68The
69.Pa /dev/aac?
70device nodes provide access to the management interface of the controller.
71One node exists per installed card.
72The aliases
73.Pa /dev/afa?
74and
75.Pa /dev/hpn?
76exist for compatibility with the Dell and HP versions of management tools,
77respectively.
78If the kernel is compiled with the
79.Dv COMPAT_LINUX
80option, or the
81.Pa aac_linux.ko
82and
83.Pa linux.ko
84modules are loaded, the
85Linux-compatible
86.Xr ioctl 2
87interface for the management device will be enabled and will allow
88Linux-based management applications to control the card.
89.Ss Tuning
90The read-only sysctl
91.Va hw.aac.iosize_max
92defaults to 65536 and may be set at boot time to another value via
93.Xr loader 8 .
94This value determines the maximum data transfer size allowed
95to/from an array.
96Setting it higher will result in better performance,
97especially for large sequential access patterns.
98.Em Beware :
99internal limitations
100of the card limit this value to 64K for arrays with many members.
101While it may be safe to raise this value, this is done
102.Em at the operator's own risk .
103Note also that
104performance peaks at a value of 96K,
105and drops off dramatically at 128K,
106due to other limitations of the card.

254Compiling with

256set to a number between 0 and 3
257will enable increasingly verbose debug messages.
258.Pp
259The adapter can send status and alert messages asynchronously
260to the driver.
261These messages are printed on the system console,
262and are also queued for retrieval by a management application.

280.Sh BUGS
281This driver is not compatible with Dell controllers that have version 1.x
282firmware.
283The firmware version is the same as the kernel version printed in the BIOS
284POST and driver attach messages.
285.Pp
286The controller is not actually paused on suspend/resume.
