42 .Nd LSI Fusion-MPT 2 Serial Attached SCSI driver
44 To compile this driver into your kernel,
45 place the following lines in your kernel configuration file:
46 .Bd -ragged -offset indent
51 Or, to load the driver as a module at boot, place the following line in
53 .Bd -literal -offset indent
59 driver provides support for LSI Logic Fusion-MPT 2
65 driver supports the following controllers:
69 LSI Logic SAS2004 (4 Port
72 LSI Logic SAS2008 (8 Port
75 LSI Logic SAS2108 (8 Port
78 LSI Logic SAS2116 (16 Port
81 LSI Logic SAS2208 (8 Port
85 To disable MSI interrupts for all
87 driver instances, set the following tunable value in
89 .Bd -literal -offset indent
93 .\"To disable MSI-X interrupts for all
95 .\"driver instances, set the following tunable value in
96 .\".Xr loader.conf 5 :
97 .\".Bd -literal -offset indent
98 .\"hw.mps.disable_msix=1
101 To allow the driver to send multiple task management commands (like abort,
102 LUN reset, etc.), set the following variable:
103 .Bd -literal -offset indent
104 hw.mps.X.allow_multiple_tm_cmds=1
111 where X is the adapter number.
112 By default the driver only sends one task management command at a time, to
113 avoid causing a potential controller lock-up.
115 To enable debugging prints from the
118 .Bd -literal -offset indent
122 variable, where X is the adapter number, either in
126 The following bits have the described effects:
127 .Bl -tag -offset indent -width "0x01"
129 Enable informational prints.
131 Enable tracing prints.
133 Enable prints for driver faults.
135 Enable prints for controller events.

155 driver was originally written by
156 .An Scott Long Aq scottl@FreeBSD.org .
157 This man page was written by
158 .An Ken Merry Aq ken@FreeBSD.org .
160 This driver is still in development, it has only been tested on the amd64
161 architecture and has some known shortcomings:
164 No IR (Integrated RAID) support.
166 No userland utility support (e.g.
169 Sometimes the driver gets into a state where devices arrive and depart multiple
170 times, without user intervention.
172 The error recovery code isn't complete.
