39.Dt MPT 4
40.Os
41.Sh NAME
42.Nm mpt
43.Nd LSI Fusion-MPT SCSI/Fibre Channel driver
44.Sh SYNOPSIS
45To compile this driver into the kernel,
46place the following lines in your
47kernel configuration file:
48.Bd -ragged -offset indent
49.Cd "device scbus"
50.Cd "device mpt"
51.Ed
52.Pp
53Alternatively, to load the driver as a
54module at boot time, place the following line in
55.Xr loader.conf 5 :
56.Bd -literal -offset indent
57mpt_load="YES"
58.Ed
59.Sh DESCRIPTION
60The
61.Nm
62driver provides support
63for the LSI Logic Fusion-MPT family of
64.Tn SCSI ,
65.Tn Fibre Channel
66and
67.Tn SAS
68controllers.
69.Sh HARDWARE
70The following controllers are supported by the
71.Nm
72driver:
73.Pp
74.Bl -bullet -compact

76LSI Logic 53c1030,
77LSI Logic LSI2x320-X

110(Dual 4Gb/s
111.Tn Fibre Channel PCI-Express)
112.El
113.Pp
114The
115.Tn Ultra 320 SCSI
116controller chips supported by the
117.Nm
118driver can be found onboard on many systems including:
119.Pp
120.Bl -bullet -compact
121.It
122Dell PowerEdge 1750 through 2850
123.It
124IBM eServer xSeries 335
125.El
126.Pp
127These systems also contain Integrated RAID Mirroring and Integrated
128RAID Mirroring Enhanced which this driver also supports.
129.Pp
130The
131.Tn SAS
132controller chips are also present on many new AMD/Opteron based systems,
133like the Sun 4100.
134Note that this controller can drive both SAS and SATA
135drives or a mix of them at the same time.
136The Integrated RAID Mirroring
137available for these controllers is poorly supported at best.
138.Pp
139The
140.Tn Fibre Channel
141controller chipset are supported by a broad variety of speeds and systems.
142The
143.Tn Apple
144Fibre Channel HBA is in fact the
145.Tn FC949ES
146card.
147.Pp
148This driver also supports target mode for Fibre Channel cards.
149This support may be enabled by setting the desired role of the core via
150the LSI Logic firmware utility that establishes what roles the card
151can take on - no separate compilation is required.
152.Sh WARNINGS
153Most controllers supported by the
154.Nm
155driver suffer from limitations on supported disk size (mostly <2TB).
156While most controllers will truncate usable disk size, others might
157behave unexpetedly and can cause severe data loss.
158Refer to the datasheet of the chipset and firmware version for information
159about supported disk size and limitations.
