MFI(4)                 FreeBSD Kernel Interfaces Manual                 MFI(4)

NAME
     mfi -- LSI MegaRAID SAS driver

SYNOPSIS
     To compile this driver into the kernel, place the following lines in your
     kernel configuration file:

           device pci
           device mfi

     Alternatively, to load the driver as a module at boot time, place the
     following line in loader.conf(5):

           mfi_load="YES"

DESCRIPTION
     This driver is for LSI's next generation PCI Express SAS RAID con-
     trollers.  Access to RAID arrays (logical disks) from this driver is pro-
     vided via /dev/mfid? device nodes.  A simple management interface is also
     provided on a per-controller basis via the /dev/mfi? device node.

     The mfi name is derived from the phrase "MegaRAID Firmware Interface",
     which is substantially different than the old "MegaRAID" interface and
     thus requires a new driver.  Older SCSI and SATA MegaRAID cards are sup-
     ported by amr(4) and will not work with this driver.

HARDWARE
     The mfi driver supports the following hardware:

     o   LSI MegaRAID SAS 8408E
     o   LSI MegaRAID SAS 8480E
     o   Dell PERC5/i

FILES
     /dev/mfid?  array/logical disk interface
     /dev/mfi?   management interface

SEE ALSO
     amr(4), pci(4)

HISTORY
     The mfi driver first appeared in FreeBSD 7.0.

AUTHORS
     The mfi driver and this manual page were written by Scott Long
     <scottl@FreeBSD.org>.

BUGS
     The driver does not support big-endian architectures at this time.
