NAME
tws -- 3ware 9750 SATA+SAS 6Gb/s RAID controller card driver SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device scbus device tws Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): tws_load="YES" DESCRIPTION
The tws driver provides support for LSI's 3ware 9750 SATA+SAS 6Gb/s RAID controller cards. These controllers feature the LSISAS2108 6Gb/s SAS RAID-on-Chip (ROC) and are available in 4- and 8-port configurations, supports RAID levels 0, 1, 5, 6, 10, 50 and single disk, with 96 SATA and/or SAS hard drives and SSDs. For further hardware information, see http://www.lsi.com/. HARDWARE
The tws driver supports the following SATA/SAS RAID controller: o LSI's 3ware SAS 9750 series LOADER TUNABLES
Tunables can be set at the loader(8) prompt before booting the kernel or stored in loader.conf(5). hw.tws.cam_depth The maximum queued CAM SIM requests for one controller. The default value is 256. hw.tws.enable_msi This tunable enables MSI support on the controller if set to a non-zero value. The default value is 0. hw.tws.queue_depth The maximum queued requests for one controller. hw.tws.use_32bit_sgls Limit the driver to use only 32-bit SG elements regardless whether the operating system is running in 64-bit mode. The default value is 0. FILES
/dev/da? array/logical disk interface /dev/tws? management interface DIAGNOSTICS
Whenever the driver encounters a command failure, it prints out an error code in the format: "ERROR: (<error source>: <error code>):", fol- lowed by a text description of the error. There are other error messages and warnings that the driver prints out, depending on the kinds of errors that it encounters. If the driver is compiled with TWS_DEBUG defined, it prints out a whole bunch of debug messages. SEE ALSO

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. SEE ALSO
