To compile this driver into the kernel, place the following lines in your
kernel configuration file:
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
The tws driver provides support for LSI's 3ware 9750 series SATA/SAS con-
These controllers are available in 4, 8, 16 or 24-port configurations,
and support the following RAID levels: 0, 1, 10, 5, 50, 6. The device
nodes for the controllers are of the form /dev/twsX, where X is the con-
troller number. The driver is implemented as a SCSI SIM under CAM, and,
as such, the logical units that it controls are accessible via the device
nodes, /dev/daY, where Y is the logical unit number.
By default, the driver will use MSI if it is supported. This
behavior can be turned off by setting this tunable to 0.
The tws driver supports the following SATA RAID controllers:
* LSI's 3ware SAS 9750-4i
* LSI's 3ware SAS 9750-4i4e
* LSI's 3ware SAS 9750-8i
* LSI's 3ware SAS 9750-8e
* LSI's 3ware SAS 9750-16i4e
* LSI's 3ware SAS 9750-24i4e
