NAME
     aac - Adaptec AdvancedRAID Controller driver

SYNOPSIS
     aac* at pci? dev ? function ?
     ld* at aac? unit ?

DESCRIPTION
     The aac 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:

     +   Adaptec AAC-364
     +   Adaptec SCSI RAID 2120S
     +   Adaptec SCSI RAID 2200S
     +   Adaptec SCSI RAID 5400S
     +   Dell PERC 2/Si
     +   Dell PERC 2/QC
     +   Dell PERC 3/Di
     +   Dell PERC 3/Si
     +   HP NetRAID 4M

     Access to RAID containers is available via the ld device driver.  Indi-
     vidual 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.

DIAGNOSTICS
     The adapter can send status and alert messages asynchronously to the
     driver.  These messages are printed on the system console.

HISTORY
     The aac driver first appeared in NetBSD 1.6.

AUTHORS
     Mike Smith <msmith@freebsd.org> and Scott Long <scottl@freebsd.org> wrote
     the aac driver for FreeBSD, and Andrew Doran <ad@netbsd.org> ported it to
     NetBSD.

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.
