<p class="Pp">The <code class="Nm">aac</code> driver provides support for the
Adaptec AAC family of SCSI Ultra2, Ultra160, and Ultra320, SATA and SAS RAID
controllers.</p>
<p class="Pp">Access to RAID containers is available via the
<span class="Pa">/dev/aacd?</span> device nodes. The
<code class="Nm">aacp</code> device enables the SCSI pass-thru interface and
allows devices connected to the card such as CD-ROMs to be available via the
CAM <a class="Xr">scsi(4)</a> subsystem. Note that not all cards allow this
interface to be enabled.</p>
<p class="Pp">The <span class="Pa">/dev/aac?</span> device nodes provide access
to the management interface of the controller. One node exists per installed
card. The aliases <span class="Pa">/dev/afa?</span> and
<span class="Pa">/dev/hpn?</span> exist for compatibility with the Dell and
HP versions of management tools, respectively. If the
<span class="Pa">aac_linux.ko</span> and <span class="Pa">linux.ko</span>
modules are loaded, the Linux-compatible <a class="Xr">ioctl(2)</a>
interface for the management device will be enabled and will allow
Linux-based management applications to control the card.</p>
