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 in

terface 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" in

terface 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:

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

FILES

/dev/mfid? array/logical disk interface
