Installing the Controller and Drives If you already have an operating system installed on a hard drive connected to the motherboard and you want to boot a second operating system from the RAID controller: 1 Enter the system Setup. 2 Navigate to the hard drive boot sequence. 3 Move the boot controller to the top of the list. Creating a Bootable RAID 5 Array Note: If you want to install an operating system on a drive or array connected to your Adaptec RAID controller, read this section. Otherwise, skip to installing the driver in your existing operating system, as described in Chapter 3. This section describes how to create a bootable RAID 5 array with at least three drives. The following methods are described. Choose the method you prefer: ■ Using the Adaptec RAID Configuration (ARC) Utility-Use this method if you prefer a text-based approach. ■ Using the Adaptec Installation CD-Use this method if you prefer a graphical interface-based approach. Why build a RAID 5? This array level is supported by your controller. It provides a versatile combination of performance and redundancy on a minimum of three drives. Because RAID 5 uses parity, it is the safest, and most recoverable, of all RAID levels. What if I prefer a different array level? That's no problem. Once you build your array and install your operating system, you can change array levels (see Array Level Migration on page 1-9) or expand the capacity of the array (see Online Capacity Expansion on page 1-8) to suit your needs. 2-5

connected to the motherboard and you want to boot a second
operating system from the RAID controller:
1
Enter the system Setup.
2
Navigate to the hard drive boot sequence.
3
Move the boot controller to the top of the list.
Creating a Bootable RAID 5 Array
Note:
If you want to install an operating system on a drive or
array connected to your Adaptec RAID controller, read this
section. Otherwise, skip to installing the driver in your
existing operating system, as described in
Chapter 3
.
This section describes how to create a bootable RAID 5 array with
at least three drives.
The following methods are described. Choose the method you prefer:
■
Using the Adaptec RAID Configuration (ARC) Utility
—Use this
method if you prefer a text-based approach.
■
Using the Adaptec Installation CD
—Use this method if you prefer
a graphical interface-based approach.
Why build a RAID 5?
This array level is supported by your controller. It provides a
versatile combination of performance and redundancy on a
minimum of three drives. Because RAID 5 uses parity, it is the
safest, and most recoverable, of all RAID levels.
What if I prefer a different array level?
That’s no problem. Once you build your array and install your
operating system, you can change array levels (see
Array Level
Migration
on page 1-9
) or expand the capacity of the array (see
Online Capacity Expansion
on page 1-8
) to suit your needs.
