mfii
— LSI Logic
MegaRAID SAS Fusion RAID controller
mfii* at pci?
The mfii
driver provides support for the
MegaRAID SAS Fusion family of RAID controllers using the following
chipsets:
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, they appear as SCSI controllers. All RAID configuration is done through the controllers' BIOSes.
mfii
supports monitoring of the logical
disks in the controller through the
bioctl(8) and
envstat(8) commands.
The mfii
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.

The mfii

8.0.
The mfii
driver was written by
