RAID controllers, including:

M5014
These controllers support RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50 and
RAID 60 using either SAS or SATA II drives.
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.
mfi supports monitoring of the logical disks in the controller
through the
bioctl(8) and
envstat(8) commands.
EVENTS
The
mfi driver is able to send events to
powerd(8) if a logical drive in
the controller is not online. The
state-changed event will
be sent to the
/etc/powerd/scripts/sensor_drive script when
such condition happens.
