mfi
— LSI Logic
& Dell MegaRAID SAS RAID controller
mfi* at pci? dev ? function ?
The mfi
driver provides support for the
MegaRAID SAS family of RAID controllers, including:
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.
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.

driver first appeared in
