MPT(4)		       FreeBSD 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 through 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 sup-
     port 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.

WARNINGS
     Most controllers supported	by the mpt driver suffer from limitations on
     supported disk size (mostly <2TB).	 While most controllers	will truncate
     usable disk size, others might behave unexpetedly and can cause severe
     data loss.	 Refer to the datasheet	of the chipset and firmware version
     for information about supported disk size and limitations.

HISTORY
     The mpt driver first appeared in FreeBSD 4.6.

AUTHORS
     The mpt driver was	originally written for FreeBSD by Greg Ansley and
     marginally	improved upon by Matt Jacob <mjacob@FreeBSD.org>.

     Justin Gibbs <gibbs@FreeBSD.org> and Scott	Long <scottl@FreeBSD.org> have
     made more substantial improvements.
