Adaptec RAID 2045 Adaptec RAID 2405 Adaptec RAID 2445 Adaptec RAID 2805 Without this change these devices are supported by the driver's family support, but they then appear as "Adaptec RAID Controller" in boot messages and the dev.aac.0.%desc sysctl.

.Sh NAME
|
|
.Nm aac
|
|
.Nd Adaptec AdvancedRAID Controller driver
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd device pci
|
|
.Cd device aac
|
|
.Cd device aacp
|
|
.Pp
|
|
To compile in debugging code:
|
|
.Cd options AAC_DEBUG=N
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
aac_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the Adaptec AAC family of SCSI Ultra2, Ultra160,
|
|
and Ultra320, SATA and SAS RAID controllers.
|
|
.Pp
|
|
Access to RAID containers is available via the
|
|
.Pa /dev/aacd?
|
|
device nodes.
|
|
The
|
|
.Nm 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
|
|
.Xr scsi 4
|
|
subsystem.
|
|
Note that not all cards allow this interface to be enabled.
|
|
.Pp
|
|
The
|
|
.Pa /dev/aac?
|
|
device nodes provide access to the management interface of the controller.
|
|
One node exists per installed card.
|
|
The aliases
|
|
.Pa /dev/afa?
|
|
and
|
|
.Pa /dev/hpn?
|
|
exist for compatibility with the Dell and HP versions of management tools,
|
|
respectively.
|
|
If the kernel is compiled with the
|
|
.Dv COMPAT_LINUX
|
|
option, or the
|
|
.Pa aac_linux.ko
|
|
and
|
|
.Pa linux.ko
|
|
modules are loaded, the
|
|
Linux-compatible
|
|
.Xr ioctl 2
|
|
interface for the management device will be enabled and will allow
|
|
Linux-based management applications to control the card.
|
|
.Ss Tuning
|
|
The read-only sysctl
|
|
.Va hw.aac.iosize_max
|
|
defaults to 65536 and may be set at boot time to another value via
|
|
.Xr 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.
|
|
.Em 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
|
|
.Em at the operator's own risk .
|
|
Note also that
|
|
performance peaks at a value of 96K,
|
|
and drops off dramatically at 128K,
|
|
due to other limitations of the card.

and are also queued for retrieval by a management application.

.Sh 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.
|
|
.Pp
|
|
The controller is not actually paused on suspend/resume.
