MFI(4) BSD 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 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 supported by amr(4) and will not work with this driver.
Two sysctls are provided to tune the mfi driver's behavior when a request is made to remove a mounted volume. By default the driver will
disallow any requests to remove a mounted volume. If the sysctl dev.mfi.%d.delete_busy_volumes is set to 1, then the driver will allow
mounted volumes to be removed.
HARDWARE
The mfi driver supports the following hardware:
o LSI MegaRAID SAS 1078
o LSI MegaRAID SAS 8408E
o LSI MegaRAID SAS 8480E
o LSI MegaRAID SAS 9260
o Dell PERC5
o Dell PERC6
o IBM ServeRAID M5015 SAS/SATA
o IBM ServeRAID-MR10i
o Intel RAID Controller SROMBSAS18E
FILES
/dev/mfid? array/logical disk interface
/dev/mfi? management interface
DIAGNOSTICS
mfid%d: Unable to delete busy device An attempt was made to remove a mounted volume.

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

MPT(4) BSD Kernel Interfaces Manual MPT(4)NAME
mpt -- LSI Fusion-MPT SCSI/Fibre Channel driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device scbus
device mpt
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
mpt_load="YES"
DESCRIPTION
The mpt driver provides support for the LSI Logic Fusion-MPT family of SCSI, Fibre Channel and SAS controllers.
HARDWARE
The following controllers are supported by the mpt driver:
o LSI Logic 53c1030, LSI Logic LSI2x320-X (Single and Dual Ultra320 SCSI)
o LSI Logic AS1064, LSI Logic AS1068 (SAS/SATA)
o LSI Logic FC909 (1Gb/s Fibre Channel)
o LSI Logic FC909A (Dual 1Gb/s Fibre Channel)
o LSI Logic FC919, LSI Logic 7102XP-LC (Single 2Gb/s Fibre Channel)
o LSI Logic FC929, LSI Logic FC929X, LSI Logic 7202XP-LC (Dual 2Gb/s Fibre Channel)
o LSI Logic FC949X (Dual 4Gb/s Fibre Channel)
o LSI Logic FC949E, LSI Logic FC949ES (Dual 4Gb/s Fibre Channel PCI-Express)
The Ultra 320 SCSI controller chips supported by the mpt driver can be found onboard on many systems including:
o Dell PowerEdge 1750 thru 2850
o IBM eServer xSeries 335
These systems also contain Integrated RAID Mirroring and Integrated RAID Mirroring Enhanced which this driver also supports.
The SAS controller chips are also present on many new AMD/Opteron based systems, like the Sun 4100. Note that this controller can drive both
SAS and SATA drives or a mix of them at the same time. The Integrated RAID Mirroring available for these controllers is poorly supported at
best.
The Fibre Channel controller chipset are supported by a broad variety of speeds and systems. The Apple Fibre Channel HBA is in fact the
FC949ES card.
This driver also supports target mode for Fibre Channel cards. This support may be enabled by setting the desired role of the core via the
LSI Logic firmware utility that establishes what roles the card can take on - no separate compilation is required.
