NAME
mfii —
LSI Logic MegaRAID SAS Fusion
RAID controller
SYNOPSIS
mfii* at pci?
DESCRIPTION
The
mfii driver provides support for the MegaRAID SAS Fusion
family of RAID controllers using the following chipsets:
- SAS2208
- SAS3008
- SAS3108
- SAS3404
- SAS3408
- SAS3416
- SAS3504
- SAS3508
- SAS3516
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.
EVENTS
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.
