MegaRAID SAS Device Driver Installation User Guide Chapter 7: FreeBSD Driver Installation | Upgrading the Driver on an Existing FreeBSD System
Chapter 7
This chapter describes the installation of the FreeBSD driver and consists of the
following section:
 Section 7.1, Upgrading the Driver on an Existing FreeBSD System
NOTE: Currently, the FreeBSD driver is supported only on 32-bit FreeBSD.
NOTE: The FreeBSD release for FreeBSD 7.x has forward compatibility with all OS 7.x
and higher, including 8.x.
7.1 Upgrading the Driver on
an Existing FreeBSD System
When the FreeBSD operating system is already installed, the kernel image has to be
updated on the new driver module. Perform the following steps to install the FreeBSD
driver.
1. Make sure that the kernel source has been installed on the system. If the kernel
source has been installed, the /usr/src/sys directory exists.
2. Move to the arch/conf directory and copy the GENERIC configuration file to a new
file. The new file will be the kernel configuration file. Here is an example:
# cd /usr/src/sys/i386/conf
# cp GENERIC MYKERNEL
3. Enter # at the beginning of the following line in the MYKERNEL file:
device cbb #cardbus (yenta) bridge
device mfi #LSI MegaRAID SAS
4. To compile the kernel, add the following line to the
/usr/src/sys/conf/files file:
make buildkernel KERNCONF=MYKERNEL
5. To install the new kernel, type:
make installkernel KERNCONF=MYKERNEL
The new kernel is copied to the /boot/kernel directory as
/boot/kernel/kernel and the old kernel is moved to
/boot/kernel.old/kernel.
