6.1.2 Installing LSI Drivers and Software in the FreeBSD OS
This section provides detailed instructions for installing the LSI driver in the FreeBSD OS.
The following sections cover these topics:
 Installing drivers for the FreeBSD OS
 Updating drivers in the FreeBSD OS
6.1.3 Driver Installation for the FreeBSD OS
This section describes how to install the driver for your MegaRAID controller in the FreeBSD OS:
 If the virtual drives you have created are your boot device, install the driver for the controller as you install the
FreeBSD OS.
 If the operating system is already installed on a unit connected to another controller or to the motherboard, start
the FreeBSD OS, and then install the driver.
NOTE If your FreeBSD system does not have the mpt driver issue, install your MegaRAID controller in the
system before you install the LSI driver. Consult the installation guide that came with your controller for
instructions. You can download the installation guide at
http://www.lsi.com/channel/ChannelDownloads .
NOTE If your FreeBSD system has the mpt driver issue, you must disable the mpt driver and recompile the
kernel first. If you have a MegaRAID controller installed, you must power down and remove the controller from
your system and recompile the kernel. If you leave the controller in your system, the mpt driver claims the
device ID and goes into a soft reset continuously, and your system cannot exit boot. See
Section 6.4, Installing
the FreeBSD OS on Storage Managed by a MegaRAID Controller (Primary Storage) , for instructions.
