MegaRAID SAS Device Driver Installation User Guide
June 2015 FreeBSD Driver Installation
Updating Drivers in the FreeBSD System
# make buildkernel KERNCONF=MYKERNEL
g. To install the new kernel, type the following commands if your current configuration is MYKERNEL, and
press Enter.
# make installkernel KERNCONF=MYKERNEL
The new kernel is copied to the /boot/kernel directory. The old kernel is moved to the
/boot/kernel.old directory.
6. Reboot your system to use the new kernel.
When the system reboots, the new kernel driver module loads automatically.
6.6.2 Compiling and Loading the Driver as a Module by Using kldload (Dynamically Loadable
Module)
To use a driver module in case Avago does not supply a driver module for your version of the FreeBSD OS, use the
procedures in this section. If you want to install only an Avago-supplied module, see
Section 6.6.3, Updating the
MegaRAID Kernel Driver Module in the FreeBSD OS .
NOTE You can use kldload to load the driver as a module only if your boot
drive is attached to the mother board and is not managed by the
MegaRAID controller.
Perform the following steps to compile the driver as a module:
1. Boot to the FreeBSD OS.
2. Obtain driver source files; see Section 6.2, Obtaining Avago FreeBSD Drivers .
3. Make sure your kernel is prepared for the dynamically loadable module described in Section 6.6.1, Updating the
Kernel with the New Driver Source .
4. To build the driver module, type the following command, depending on which driver you use, and press Enter.
— # cd /usr/src/sys/modules/mrsas
# make clean
# make
These steps create the driver mrsas.ko module in the /usr/src/sys/modules/mrsas directory.
5. To load the kernel driver module, type the following commands and press Enter.
— # cd /usr/src/sys/modules/mrsas
# kldload -v ./mrsas.ko
6. To load the driver automatically during bootup, but still be linked dynamically, perform the following steps,
depending on which driver you use:
— To copy the MegaRAID SAS driver into the boot folder, type the following command, and press Enter.
# cp /usr/src/sys/modules/mrsas/mrsas.ko /boot/kernel/mrsas.ko
NOTE Back up the old module in case you want to revert back to it.
— Enter the following line in the /boot/loader.conf file:
mrsas_load="YES"
