Configuring The Thinkserver Raid 300 - Lenovo ThinkServer RD440 User Manual And Hardware Maintenance Manual

See "Using the ThinkServer EasyStartup program" on page 73 and view the user guide from the main
interface of the program.
Some RAID management software also is provided on the ThinkServer EasyStartup DVD to help you manage
RAID arrays and RAID controllers in an operating system environment. After you enter the operating system,
insert the ThinkServer EasyStartup DVD into the optical drive. The installation packages for the programs
are located in the Utilities and Others folder in the root directory of the DVD. The ThinkServer EasyStartup
DVD is designed for different types of servers and the Utilities and Others folder might contain additional
installation packages that are not required to be installed on your server.

Configuring the ThinkServer RAID 300

The ThinkServer RAID 300 (also known as onboard SAS software RAID) is integrated in the PCH on
the system board. If you connect the mini-SAS to mini-SAS signal cables from the system board to the
backplane, you can configure RAID for the hard disk drives using the LSI Software RAID Configuration Utility
program, independently of the operating system. The ThinkServer RAID 300 supports RAID levels 0, 1, and
10 by default. You also can activate RAID 5 by installing a ThinkServer RAID 300 Upgrade Key for Advanced
RAID. See "Installing or removing the ThinkServer RAID 300 Upgrade Key for Advanced RAID" on page 125.
You can install and use the MegaRAID Storage Manager program to manage the RAID array and RAID
controller in an operating system environment.
Before configuring RAID for your server, observe the following precautions:
• Use hard disk drives that are of the same type (SATA or SAS) and have the same capacity within a
single RAID array.
• The total drive capacity of the primary RAID array might be limited to 2 TB.
RAID array status
When you turn on the server, the RAID controller ROM version, the RAID array status, and the list of the
available hard disk drives will be displayed during the POST.
The RAID array status can be one of the following:
• Online
This is the normal status, which indicates that the RAID array is working correctly.
• Degrade
This status indicates that more than one hard disk drive in the RAID array cannot be synchronized or have
failed. You need to replace the failing hard disk drives and rebuild the data. See "Installing or replacing a
hot-swap hard disk drive" on page 172 and "Rebuilding a physical drive" on page 82.
• Offline
This status indicates that the RAID array has failed and cannot be rebuilt. You need to create a RAID
array. See "Creating, adding, or deleting a RAID array" on page 81.
Starting the LSI Software RAID Configuration Utility program
This topic provides instructions on how to start the LSI Software RAID Configuration Utility program.
To start the LSI Software RAID Configuration Utility program, do the following:
1. Turn on the server.
2. During the POST, when you see the message "Press Ctrl-M or Enter to run LSI Software RAID Setup
Utility," immediately press Ctrl+M to start the LSI Software RAID Configuration Utility program.
