Use the Adaptec HostRAID Configuration Utility program to add RAID level-0 and
level-1 functionality to the integrated Serial ATA controller (simple-swap SATA
models). Be sure to use this program as described in this document. Use this
program to perform the following tasks:
v Configure a redundant array of independent disks (RAID) array
v View or change the RAID configuration and associated devices
When
you are using the Adaptec RAID Configuration Utility program to configure
and manage simple-swap SATA arrays, consider the following information:
v The integrated Serial ATA controller with integrated SATA RAID (simple-swap
SATA models) supports RAID level-0 and level-1 with the option of having a
hot-spare drive.
v You cannot use the ServerGuide Setup and Installation CD to configure the
integrated Serial ATA controller with integrated RAID.
v Hard disk drive capacities affect how you create arrays. Drives in an array can
have different capacities, but the RAID controller treats them as if they all have
the capacity of the smallest hard disk drive.
v To help ensure signal quality, do not mix drives with different speeds and data
rates.
Using the Adaptec RAID Configuration Utility program
Use the Array Configuration Utility to add RAID level-0 and level-1 functionality to
the integrated Serial ATA (SATA) controller. This utility is a part of the BIOS code.
For additional information about using the Adaptec RAID Configuration Utility
program, see the documentation on the Adaptec HostRAID Support CD. If this CD
did not come with the server, you can download it from http://www.ibm.com/
support/.
Using the SATA HostRAID feature
The instructions in this section are for using the Array Configuration Utility program
to access and perform an initial RAID level-1 configuration.
For additional information about using the Array Configuration Utility program to
create, configure, and manage arrays, see the documentation on the Adaptec
HostRAID Support CD.
Configuring the controller: To use the Array Configuration Utility program to
configure a RAID level-1 array, complete the following steps:
1. Turn on the server.
2. When the prompt Press <CTRL><<A> for Adaptec RAID Configuration
Utility appears, press Ctrl+A.
3. Select Array Configuration Utility.
4. Select Create Array.
5. From the list of ready drives, select the two drives that you want to group into
the array.
6. When you are prompted to select the RAID level, select RAID-1.
7. (Optional) Type an identifier for the array.
8. When you are prompted for the array build method, select Quick Int.
9. Follow the instructions on the screen to complete the configuration, and select
Done to exit.
10. Restart the server.
