Using the RAID Configuration Utility 5
2 Using the RAID Configuration Utility
The RAID Configuration Utility is loaded on the controller ROM. To run the utility, press the Ctrl+A keys or the F8
key (depending on the version of the ROM) when prompted by one of the following messages during system
startup:
Press <Ctrl><A> for Adaptec RAID Configuration Utility
Press <F8> for HP Embedded SATA Setup
To select an option from any of the menus within the RAID Configuration Utility, browse with the arrow keys, and
then press the Enter key. In some cases, selecting an option displays another menu. To return to the previous
menu at any time, press the Esc key.
The main option on the RAID Configuration Utility menu is the array configuration utility, which enables you to
perform the following tasks:
• Create an array
• Manage an array
• Add or delete a hotspare
• Configure a drive
• Rebuild an array
• Verify drives
The procedures for performing each of these tasks are described in the following sections.
Creating an array
Before creating an array, be sure that the drives to be used for the array are installed in your system and have
been configured (see “Configuring a drive” on page 7). If the utility displays a drive in gray, the drive does not
have any usable space, and it cannot be used to create an array.
CAUTION: Before adding a drive to an array, back up any data that is already on the drive. Otherwise, the
data will be lost.
To create an array:
1. Power down the computer, and then restart it.
2. When the appropriate prompt appears during POST, press the Ctrl+A keys or the F8 key to access the RAID
Configuration Utility.
3. From the menu, select Array Configuration Utility.
4. From the array configuration utility menu, select Create Array.
5. Highlight a drive to be used in the new array, and then press the Insert key.
6. Repeat the previous step to select another drive. (To deselect a drive, highlight the drive and press the
Delete key.)
7. When all drives for the new array are selected, press the Enter key.
The Array Properties menu appears, showing the RAID levels (types of array) that can be configured for the
selected number of drives. (For this controller, RAID 0 and RAID 1 are shown, and RAID 10 is shown if the
server supports it. RAID 0 can have from two to four drives, RAID 1 requires two drives, and RAID 10
requires four drives.)
8. Select the RAID level that you want to create, and press the Enter key.
9. (Optional) Enter a label of no more than 15 characters to identify the array.
10. If you are creating a RAID 0 or RAID 10 array, you can change the stripe size that the array uses, although
in general it is best to stay with the default size of 64 KB. Available stripe sizes are 16, 32, and 64 KB.
