SYNOPSIS
mfii* at pci?
DESCRIPTION
Themfii 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.
