Configuring the ThinkServer RAID 100 or RAID 300

The ThinkServer RAID 100 or RAID 300 (also known as onboard SATA/SAS software RAID) is integrated in
the PCH on the system board. If you connect the signal cables from the system board to the hard disk drives
or 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 100 or RAID 300 supports
RAID levels 0, 1, and 10 by default. You also can activate RAID 5 by installing a ThinkServer RAID 100 or
RAID 300 Upgrade Key for Advanced RAID. See "Installing or removing the ThinkServer RAID 100 or RAID
300 upgrade key for Advanced RAID" on page 112.
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 is 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 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 130 and "Rebuilding a physical drive" on page 77.
• Offline
This status indicates that the RAID array has failed and cannot be rebuilt. You need to create a new RAID
array. See "Creating, adding, or deleting a RAID array" on page 76.
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.
