Chapter 2: MegaRAID SAS Hardware Installation
After Installing the RAID Controller
7. Turn on the power to the system.
Reinstall the computer cover, and reconnect the AC power cords. Turn on power to the host computer. Make sure
that the power is turned on to the SAS devices, SATA devices, or both before or at the same time that the power
is turned on to the host computer. If the computer is powered on before these devices, the devices 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 shows the 12Gb/s MegaRAID
SATA+SAS RAID controller number, firmware version, and cache SDRAM size. The numbering of the controllers
follows the PCI slot scanning order used by the host motherboard.
8. Run the WebBIOS™ Configuration Utility.
Run the WebBIOS Configuration Utility to configure the drive groups and the virtual drives. When the message
Press CTRL+H for WebBIOS
appears on the screen, immediately press Ctrl+H to run the utility.
9. Install the operating system driver.
MegaRAID 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 for RAID controllers from the LSI website.
For information about installing the driver, refer to the MegaRAID SAS Device Driver Installation User Guide on the
MegaRAID Universal Software Suite CD. Be sure to use the latest service packs provided by the operating system
manufacturer and to review the readme file that accompanies the driver.
2.4 After Installing the RAID Controller
After you install the 12Gb/s MegaRAID SATA+SAS RAID controller, you must configure the controller and install the
operating system driver. The MegaRAID SAS Software User Guide instructs you on the configuration options and how to
set them on your 12Gb/s MegaRAID SATA+SAS RAID controller. The MegaRAID SAS Device Driver Installation User Guide
provides detailed installation instructions for operating system drivers.
2.5 SAS Device Cables and Connectors
This section describes the cables and the connectors used on the MegaRAID SAS controllers and provides
step-by-step instructions for connecting SAS drives, SATA drives, or both to the MegaRAID SAS RAID controller. The
SAS protocol and the SATA protocol use a thin, 7-wire connector instead of the 68-wire SCSI cable or the 40-wire
ATA cable.
NOTE Use only straight SAS cables, not crossover SAS cables.
The following figure shows the SAS cable that connects the internal connectors on a SAS RAID controller to SAS drives,
SATA drives, or both.
