Appendix C: Using the Adaptec RAID Configuration Utility ● 82
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 settings, select Controller Configuration from the main -Select
utility menu.
The following table lists controller configuration options. Some options may not be available
for your controller. Additional, controller-specific options are also available:
● For SAS controller-specific settings, see page 83.
● For SATA controller-specific settings, see page 83.
● For SCSI controller-specific settings, see page 84.
General Controller Settings
Note: Default settings are shown in bold type.
Option Description
Drive’s Write Cache When enabled, write cache is enabled on the disk drive. When disabled,
write cache is not used on the disk drive. Default is the disk drive’s
setting.
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.
BBS Support When enabled in systems that support BBS, the RAID controller is
presented as a bootable device in the BIOS.
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.
Physical Drives Display
During POST
When enabled, connected disk drives are displayed during system Power
On Self Test (POST). Displaying the disk drives adds a few seconds to
the overall POST time. Default is disabled.
CD-ROM Boot Support When enabled, the system can be booted from a bootable CD. (This
setting is not available on all RAID controller models.)
Note—CD’s are not supported by current software.
Removable Media
Devices Boot Support
When enabled, removable media devices, such as CD drives, are
supported. (This setting is not available on all RAID controller models.)
Alarm Control When enabled, the alarm sounds. Default is enabled.
Note—When the alarm is turned off (disabled), it will automatically turn
back on after a reboot.
