.Nm aac
|
|
.Nd Adaptec AdvancedRAID Controller driver
|
|
.Sh SYNOPSIS
|
|
.Cd options AAC_DEBUG=N
|
|
.Cd device pci
|
|
.Cd device aac
|
|
.Cd device aacp
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the Adaptec AAC family of SCSI Ultra2, Ultra160,
|
|
and Ultra320, and SATA 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 cdroms 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 compatibilty 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.

Compiling with

set to a number between 0 and 3
|

will enable increasingly verbose debug messages.
|
|
.Pp
|
|
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.

.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.
