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
     controllers.  Access to RAID arrays (logical disks) from this driver is
     provided 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
     supported by amr(4) and will not work with this driver.

HARDWARE

     The mfi driver supports the following hardware:

     ·   LSI MegaRAID SAS 8408E
     ·   LSI MegaRAID SAS 8480E
     ·   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.

BUGS

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