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.
