MegaRAID SAS Hardware Installation

The maximum cable length is 6 external meters. You can
connect one device per SAS PHY unless you use an expander.

System throughput problems can occur if the SAS cables are
not the correct type. To minimize the potential for problems, use
the following guidelines:

a.

Use cables no longer than 6 meters (LSI Logic
recommends using shorter cables, if possible).

b.

Use cables that meet the SAS specification.

c.

Route the SAS cables carefully.

Step 8.

Turn on the Power to the System

Replace the computer cover, and reconnect the AC power
cords. Turn power on to the host computer. Make sure that the
power is turned on to the SAS devices, SATA II devices, or both
are powered up before or at the same time that the power is
turned on to the host computer. If the computer is powered up
before a SAS device, SATA II device, or both, the device might
not be recognized.

During boot, a BIOS message appears. The firmware takes
several seconds to initialize. The configuration utility prompt
times out after several seconds. The second portion of the
BIOS message displays the MegaRAID controller, number,
firmware version, and cache SDRAM size. The numbering of
the controllers follows the PCI slot scanning order used by the
host system board.

Step 9.

Run the WebBIOS Configuration Utility

Run the WebBIOS Configuration Utility to configure the physical
arrays and the logical drives. When the message Press

for WebBIOS

appears on the screen, press

CTRL+H immediately to run the utility.

Step 10. Install the Operating System Driver

The SAS RAID controllers can operate under various operating
systems. To operate under these operating systems, you must
install the software drivers. The MegaRAID Universal Software
Suite
CD includes software drivers for the supported operating
systems, along with documentation. You can view the
supported operating systems and download the latest drivers
