Starting the Intel Embedded Server RAID Technology II program
To start the Intel Embedded Server RAID Technology II program, do the following:
1. During the POST, when you see the message “Press <Ctrl> <E> to enter Embedded RAID II
Conguration Utility”, press Ctrl+E to enter the main menu for the SATA RAID conguration program.
2. Follow the instructions on the screen to congure the SATA RAID. When working with this program,
you must use the keyboard. The keys used to perform various tasks are displayed at the bottom
of each screen.
The main menu of the SATA RAID conguration program includes the following items:
• The Congure item is for conguring the RAID volume, including creating a new volume, deleting a
volume, adding a volume, and setting the RAID volume boot sequence.
• The Initialize item is for initializing the RAID volume.
• The Objects item is for selecting Adapter, Logical drive, or Physical Drive and doing related settings.
• The Rebuild item is for rebuilding the RAID volume.

Creating a RAID volume
This section provides instructions on how to create a RAID volume by using the Intel Embedded Server
RAID Technology II program.
There are three methods to create a RAID volume:
• Easy Conguration: Using all hard disk drives to create a RAID array. You can set the stripe size by using
this method, however, you cannot select the capacity of the array.
• New Conguration: If you use this method to create a RAID array, the existing RAID array will be deleted.
You can select both the stripe size and the array capacity for the new RAID array.
• View/Add Conguration: Viewing the current RAID array, adding a new RAID array, or reconguring
the current RAID array.
Note: If you use the Easy Conguration to create a new RAID volume, the current RAID volume will be
deleted. If you want to create a new RAID volume without deleting the current data, use the View/Add
Conguration.
To create a RAID volume by using the Easy Conguration option, do the following:
1. Select Management ➙ Congure from the main menu and press Enter. The Conguration Menu
opens.
2. Select Easy Conguration.
3. Press the space key to select physical drives. The free physical drives will be shown as READY. After
you select one, it will be shown as ONLIN A[array number]-[hard disk drive number]. For example,
ONLIN A1-3 denotes the number 3 hard disk drive in array 1.
