+.Pp
+These controllers support RAID 0, RAID 1, RAID 5, JBOD,
+and superpositions of those configurations.
+.Pp
+Although the controllers are actual RAID controllers,
+the driver makes them look just like SCSI controllers.
+All RAID configuration is done through the controllers' BIOSes.
+.Pp
+RAID management is done through the
+.Xr bio 4
+device with the
+.Xr bioctl 8
+command.
+Logical disk status is exposed under the
+.Va hw.sensors
+.Xr sysctl 8
+and can be monitored using
+.Xr sensorsd 8 .
+For example:
+.Bd -literal -offset indent
+$ sysctl hw.sensors.ami0
+hw.sensors.ami0.drive0=online (sd0), OK
+hw.sensors.ami0.drive1=degraded (sd1), WARNING
+hw.sensors.ami0.drive2=failed (sd2), CRITICAL
