.Sh NAME
.Nm aac
.Nd Adaptec AdvancedRAID Controller driver
.Sh SYNOPSIS
.Cd "aac* at pci? dev ? function ?"
.Cd "ld* at aac? unit ?"
.Sh DESCRIPTION
The
.Nm
driver provides support for the Adaptec AAC family of SCSI RAID controllers.
These controllers support RAID 0, 1, 5, 10, and volume sets.
They have four channels in the add-in version
or 1-2 channels in the motherboard integrated version,
and are most often found relabeled by Dell or Hewlett-Packard.
Supported controllers include:

Access to RAID containers is available via the
.Nm ld
device driver.
Individual drives cannot be accessed unless they are part of a container
or volume set, and non-fixed disks cannot be accessed.
Containers can be configured by using either the on-board BIOS utility of
the card.
.Sh DIAGNOSTICS
The adapter can send status and alert messages asynchronously to the driver.
These messages are printed on the system console.

driver for
.Fx ,
and
Andrew Doran

.Sh BUGS
This driver is not compatible with 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.
