These controllers support RAID 0, RAID 1, RAID 5, JBOD, and
superpositions of those configurations.
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.
RAID management is done through the bio(4) device with the bioctl(8)
command. Logical disk status is exposed under the hw.sensors sysctl(8)
and can be monitored using sensorsd(8). For example:
$ 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
