-.Sh NAME
-.Nm twa
-.Nd 3ware 9000/9500/9550/9650 series SATA RAID controllers driver
-.Sh DEPRECATION NOTICE
-The
-.Nm
-driver is not present in
-.Fx 13.0 .
-.Sh SYNOPSIS
-To compile this driver into the kernel,
-place the following lines in your
-kernel configuration file:
-.Bd -ragged -offset indent
-.Cd "device scbus"
-.Cd "device twa"
-.Ed
-.Pp
-Alternatively, to load the driver as a
-module at boot time, place the following line in
-.Xr loader.conf 5 :
-.Bd -literal -offset indent
-twa_load="YES"
-.Ed
-.Sh DESCRIPTION
-The
-.Nm
-driver provides support for AMCC's 3ware 9000/9500/9550/9650 series
-SATA controllers.
-.Pp
-These controllers are available in 4, 8, 12 or 16-port configurations,
-and support the following RAID levels: 0, 1, 10, 5, 50.
-The device nodes for the controllers are of the form
-.Pa /dev/twa Ns Ar X ,
-where
-.Ar X
-is the controller 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,
-.Pa /dev/da Ns Ar Y ,
-where
-.Ar Y
-is the logical unit number.
-.Sh HARDWARE
-The
-.Nm
-driver supports the following SATA RAID controllers:

-.Sh DIAGNOSTICS
-Whenever the driver encounters a command failure, it prints out an error code in
-the format:
-.Qq Li "ERROR: (<error source>: <error code>):" ,
-followed 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
-.Dv TWA_DEBUG
-defined, it prints out a whole bunch of debug
-messages, the quantity of which varies depending on the value assigned to
-.Dv TWA_DEBUG
-(0 to 10).
-.Sh AUTHORS
-The
-.Nm
-driver and manpage were written by
-.An Vinod Kashyap Aq Mt vkashyap@FreeBSD.org .
