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. SEE ALSO

NAME
mps -- LSI Fusion-MPT 2 Serial Attached SCSI driver SYNOPSIS
To compile this driver into your kernel, place the following lines in your kernel configuration file: device scbus device mps Or, to load the driver as a module at boot, place the following line in loader.conf(5): mps_load="YES" DESCRIPTION
The mps driver provides support for LSI Logic Fusion-MPT 2 SAS controllers and WarpDrive solid state storage cards. HARDWARE
The mps driver supports the following hardware: o LSI Logic SAS2004 (4 Port SAS) o LSI Logic SAS2008 (8 Port SAS) o LSI Logic SAS2108 (8 Port SAS) o LSI Logic SAS2116 (16 Port SAS) o LSI Logic SAS2208 (8 Port SAS) o LSI Logic SAS2308 (8 Port SAS) o LSI Logic SSS6200 Solid State Storage o Intel Integrated RAID Module RMS25JB040 o Intel Integrated RAID Module RMS25JB080 o Intel Integrated RAID Module RMS25KB040 o Intel Integrated RAID Module RMS25KB080 CONFIGURATION
To disable MSI interrupts for all mps driver instances, set the following tunable value in loader.conf(5): hw.mps.disable_msi=1 To disable MSI interrupts for a specific mps driver instance, set the following tunable value in loader.conf(5): dev.mps.X.disable_msi=1 where X is the adapter number. To disable MSI-X interrupts for all mps driver instances, set the following tunable value in loader.conf(5): hw.mps.disable_msix=1 To disable MSI-X interrupts for a specific mps driver instance, set the following tunable value in loader.conf(5): dev.mps.X.disable_msix=1 To set the maximum number of DMA chains allocated for all adapters, set the following variable in loader.conf(5): hw.mps.max_chains=NNNN To set the maximum number of DMA chains allocated for a specific adapter, set the following variable in loader.conf(5): dev.mps.X.max_chains=NNNN This variable may also be viewed via sysctl(8) to see the maximum set for a given adapter. The current number of free chain frames may be seen via the dev.mps.X.chain_free sysctl(8) variable. The lowest number of free chain frames may be seen via the dev.mps.X.chain_free_lowwater sysctl(8) variable. The current number of active I/O commands is shown in the dev.mps.X.io_cmds_active sysctl(8) variable. The maximum number of active I/O command seen since boot is shown in the dev.mps.X.io_cmds_highwater sysctl(8) variable. DEBUGGING
To enable debugging prints from the mps driver, set the hw.mps.X.debug_level variable, where X is the adapter number, either in loader.conf(5) or via sysctl(8). The following bits have the described effects: 0x01 Enable informational prints. 0x02 Enable tracing prints. 0x04 Enable prints for driver faults. 0x08 Enable prints for controller events. SEE ALSO

The mps driver first appeared in FreeBSD 9.0. AUTHORS
The mps driver was originally written by Scott Long <scottl@FreeBSD.org>. It has been improved and tested by LSI Logic Corporation. This man page was written by Ken Merry <ken@FreeBSD.org>. BUGS
This driver has a couple of known shortcomings: o No userland utility available (e.g. mptutil(8)). o The driver probes devices sequentially. If your system has a large number of devices, the probe will take a while. BSD
