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
<scottlATFreeBSD.org>.
BUGS
The driver does not support big-endian architectures at this time.
