Appendix C: Using the Adaptec RAID Configuration Utility ● 89 Opening SerialSelect To open SerialSelect, start the ARC utility (see page 84), select SerialSelect, then press Enter. Follow the on-screen instructions to modify the settings of your controller and connected disk drives as required. Applying Changes and Exiting 1 To exit SerialSelect, press Esc until you are prompted to exit. If you modified any settings, you are prompted to save the changes before you exit. 2 Select Yes to exit, then press any key to restart your computer. Any changes you made take effect after the computer restarts. Modifying Your Controller's Configuration Note: Default controller settings are suitable for most computers. Adaptec recommends that you do not change the default setting. To modify your controller's basic settings, select Controller Configuration from the main SerialSelect menu. To modify your controller's power management settings, select Advanced Configuration. To modify your controller's PHY settings, select PHY Configuration. Some options may not be available for your controller. General Controller Settings Note: Default settings are shown in bold type. Option Drive's Write Cache Runtime BIOS Automatic Failover Array Background Consistency Check Array-based BBS Support SATA Native Command Queuing (NCQ) Description When set to Enable All, write cache is enabled on all disk drives on the controller. (Enabling the write cache overrides any individual drive settings in Adaptec Storage Manager.) When set to Disable All, write cache is not used on the disk drives. When set to Drive Specific, write cache is enabled/disabled on a per-drive basis in Adaptec Storage Manager. Caution-When write cache is enabled, there is a slight possibility of data loss or corruption during a power failure. When enabled, the controller BIOS allows the controller to act as a bootable device. Disabling the BIOS allows another controller to act as a bootable device. When enabled, the controller automatically rebuilds an array when a failed disk drive is replaced. When disabled, the array must be rebuilt manually. When enabled, the controller constantly verifies a redundant array. Note that there may be a significant performance reduction. Default is disabled. When enabled in systems that support BBS, the controller presents attached bootable devices up to the BIOS for boot device selection. This is relevant for logical arrays. Default is disabled. When enabled, NCQ is enabled. Disable this feature if you want to attach more than 48 SATA II disk drives. Only available with SATA II disk drives.

Option
Description
Drive’s Write Cache
When set to Enable All, write cache is enabled on all disk drives on the
controller. (Enabling the write cache overrides any individual drive
settings in Adaptec Storage Manager.) When set to Disable All, write
cache is not used on the disk drives. When set to Drive Specific, write
cache is enabled/disabled on a per-drive basis in Adaptec Storage
Manager.
Caution
—When write cache is enabled, there is a slight possibility of
data loss or corruption during a power failure.
Runtime BIOS
When
enabled
, the controller BIOS allows the controller to act as a
bootable device. Disabling the BIOS allows another controller to act as a
bootable device.
Automatic Failover
When
enabled
, the controller automatically rebuilds an array when a
failed disk drive is replaced. When disabled, the array must be rebuilt
manually.
Array Background
Consistency Check
When enabled, the controller constantly verifies a redundant array. Note
that there may be a significant performance reduction. Default is
disabled
.
Array-based BBS
Support
When enabled in systems that support BBS, the controller presents
attached bootable devices up to the BIOS for boot device selection. This
is relevant for logical arrays. Default is
disabled
.
SATA Native Command
Queuing (NCQ)
When
enabled
, NCQ is enabled. Disable this feature if you want to
attach more than 48 SATA II disk drives. Only available with SATA II disk
drives.
