Installing the Kernel Driver Module while Installing FreeBSD on a Unit Managed by a 3ware RAID Controller
Use this procedure if your boot unit is going to be managed by the 3ware RAID controller.
It describes how to load the FreeBSD 6.3 or FreeBSD 7.0 kernel driver module to enable boot device support and how to then compile the current drivers into the kernel from source files.
 
Note: This procedure is specific to FreeBSD 6.3 and FreeBSD 7.0 as it requires a compiled module. For versions of FreeBSD for which a compiled module is not supplied by 3ware it will be necessary to compile your own module from source files. See Compiling and Loading the Driver as a Module using kldload.
1
Disconnect all SCSI, ATA, and SAS devices in the system, except the CD or DVD and the ones connected to the 3ware RAID controller.
2
Create the RAID units on the 3ware RAID controller using 3BM. For details on how to create and order units, see "Creating a Unit through 3BM " and "Ordering Units in 3BM" on pages 91 and 95 in the 3ware SAS/SATA RAID Software User Guide, Version 9.5.
3
Copy the appropriate kernel driver module twa.ko from 3ware CD to a floppy. See Obtaining 3ware FreeBSD Drivers and Creating A FreeBSD Driver Diskette in this document for details.
4
5
Insert the floppy containing twa.ko module into floppy drive.
6
7
At the loader prompt, load twa.ko from the floppy drive by using “load disk0:twa.ko (assuming disk0 is the floppy drive).
8

10
11
At the loader prompt, load twa.ko from the floppy using "load disk0:twa.ko" (assuming disk0 is the floppy drive).
12
13
Once the system boots up, replace the twa driver sources at
/sys/dev/twa and /sys/modules/twa with the new sources and build the kernel with the new driver sources. See Updating the Kernel with the New Driver Source for more details.
