Foreign conguration found
The Foreign Conguration Found page is displayed only if a foreign conguration physical disk drive resides on the selected RAID
controller or any uninitialized physical disk drives present on the system.
A foreign conguration is a set of physical disk drives containing a RAID conguration that is introduced to the system, but is not managed
by the RAID controller to which it is attached. You may have a foreign conguration if physical disk drives have been moved from one RAID
controller to another RAID controller.
NOTE: Import Foreign Conguration is supported from System Setup > Advanced Hardware Conguration > Device
Settings.
You have two options: Ignore Foreign Conguration and Clear Foreign Conguration.
• If the foreign conguration contains data that you require, click Ignore Foreign Conguration. If you click this option, the disk drive
space containing the foreign conguration is not available for use in a new virtual drive.
• To delete all data on the physical disk drives containing the foreign conguration, click Clear Foreign Conguration. This option deletes
the hard-disk drive space containing the foreign conguration and makes it available for use in a new virtual drive.
After selecting one of the above options, click Next.
Viewing current RAID conguration
The View Current RAID Conguration and Select Controller page displays the attributes of any virtual disks already congured 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 conguration 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 Conguration 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 oers 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 oers 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 oers good read performance and slower write performance with good data
redundancy.
