6. Select the RAID level and click Next.

The Select Physical Disks page is displayed.

7. Select the physical disk's properties and click Next.

The Virtual Disk Attributes page is displayed.

8. Select the virtual disk parameters and click Next.

The Summary page is displayed.

9. To apply the RAID configuration, click Finish.

Foreign configuration found

The Foreign Configuration Found page is displayed only if a foreign configuration physical disk drive resides on the selected RAID

controller or any uninitialized physical disk drives present on the system.

A foreign configuration is a set of physical disk drives containing a RAID configuration that is introduced to the system, but is not managed

by the RAID controller to which it is attached. You may have a foreign configuration if physical disk drives have been moved from one

RAID controller to another RAID controller.

NOTE: Import Foreign Configuration is supported from System Setup > Advanced Hardware Configuration > Device

Settings.

You have two options: Ignore Foreign Configuration and Clear Foreign Configuration.

• If the foreign configuration contains data that you require, click Ignore Foreign Configuration. If you click this option, the disk drive

space containing the foreign configuration is not available for use in a new virtual drive.

• To delete all data on the physical disk drives containing the foreign configuration, click Clear Foreign Configuration. This option

deletes the hard-disk drive space containing the foreign configuration and makes it available for use in a new virtual drive.

After selecting one of the above options, click Next.

Viewing current RAID configuration

The View Current RAID Configuration and Select Controller page displays the attributes of any virtual disks already configured on

the supported RAID controllers attached to the system. You have two options:

• Accept the existing virtual disks without changing. To select this option, click Back. If you have to install the operating system on an

existing virtual disk, make sure that the virtual disk size and RAID level are correct.

• Use the RAID configuration wizard to delete all the existing virtual disks and create a single new virtual disk to be used as the new

boot device. To select this option, click Next.

NOTE:

RAID 0 does not provide data redundancy and hot spare. Other RAID levels provide data redundancy and

enable you to reconstruct data in the event of a disk-drive failure.

NOTE: You can create only one virtual disk using Lifecycle Controller. To create multiple virtual disks, use Option

ROM. To access Option ROM, press <Ctrl> <R> during boot or POST.

Selecting a RAID controller

The View Current RAID Configuration and Select Controller page displays all supported RAID controllers attached to the system.

Select the RAID controller on which you want to create the virtual disk, and then click Next.

Selecting RAID levels

Select a RAID Level for the virtual disk:

• RAID 0 — Stripes data across the physical disks. RAID 0 does not maintain redundant data. When a physical disk fails in a RAID 0

virtual disk, there is no method for rebuilding the data. RAID 0 offers good read and write performance with zero data redundancy.

• RAID 1 — Mirrors or duplicates data from one physical disk to another. If a physical disk fails, data can be rebuilt using the data from

the other side of the mirror. RAID 1 offers good read performance and average write performance with good data redundancy.

• RAID 5 — Stripes data across the physical disks, and uses parity information to maintain redundant data. If a physical disk fails, the

data can be rebuilt using the parity information. RAID 5 offers good read performance and slower write performance with good data

redundancy.
