MFI(4) MidnightBSD 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 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
