LSI MegaRAID(R) 6 Gb/s SAS RAID Controllers 25083 User Manual

 

The maximum cable length is 10 meters (393.37 in.). 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 10 meters (393.37 in.) (LSI 
recommends using shorter cables, if possible.)

b.

Use cables that meet the SAS specification.

c.

Route the SAS cables carefully.

Step 7.

Turn on the Power to the System

Reinstall 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 
before or at the same time that the power is turned on to the 
host computer. If the computer is powered up 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 MegaRAID 6Gb/s 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.

Step 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.

Step 9.

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
