Linux Driver Installation
This section explains the steps to install the embedded MegaRAID device driver in a Red Hat Enterprise
Linux installation or a SuSE Linux Enterprise Server installation.
This section contains the following topics:
• Obtaining the Driver Image File, page C-12
• Preparing Physical Installation Diskettes For Linux, page C-12
• Installing the Red Hat Linux Driver, page C-14
• Installing the SUSE Linux Enterprise Server 11 Driver, page C-15
Obtaining the Driver Image File
See Downloading the LSI MegaSR Drivers, page C-10 for instructions on obtaining the drivers. The
Linux driver is offered in the form of dud-[driver version].img, which is the boot image for the
embedded MegaRAID stack.
Note The LSI MegaSR drivers that Cisco provides for Red Hat Linux and SUSE Linux are for the original GA
versions of those distributions. The drivers do not support updates to those OS kernels.
Preparing Physical Installation Diskettes For Linux
This section describes how to prepare physical Linux installation diskettes from the driver image files,
using either the Windows operating system or the Linux operating system.
Note Alternatively, you can mount the dud.img file as a virtual floppy disk, as described in the installation
procedures.
Preparing Physical Installation Diskettes With the Windows Operating System:
Under Windows, you can use the RaWrite floppy image-writer utility to create disk images from image
files. Perform the following steps to build installation diskettes.
Step 1 Download the Cisco UCS C-Series drivers ISO, as described in Downloading the LSI MegaSR Drivers,
page C-10 and save it to your Windows system that has a diskette drive.
Step 2 Extract the dud.img file:
a. Burn the ISO image to a disc.
b. Browse the contents of the drivers folders to the location of the embedded MegaRAID drivers:
/<OS>/Storage/Intel/C600/
c. Expand the Zip file, which contains the folder with the driver files.
Step 3 Copy the driver update disk image dud-[driver version].img and your file raw write.exe to a
directory.
Note RaWrite is not included in the driver package.
