SCSI/SAS or SATA disks connected to an AacRaid controller. The non-negative integers H,L,ID (Host number, Lun, ID) denote which disk on the controller is monitored. Use syntax such as:<br>
<b>smartctl -a -d aacraid,0,0,2 /dev/sda</b><br>
<b>smartctl -a -d aacraid,1,0,4 /dev/sdb</b><o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:"Segoe UI",sans-serif;color:#DA846B">Option '-d sat,auto+...' is implicitly enabled to detect SATA disks. Use '-d scsi+aacraid,H,L,ID' to disable it.<br>
On Linux, the following entry in /proc/devices must exist: <b>aac</b>. Character device nodes /dev/aacH (H=Host number) are created if required.<br>
On Windows, the device name parameter /dev/sdX is ignored if '-d aacraid' is specified.<o:p></o:p></span></p>
