Using Adaptec RAID Configuration
Using the Controller Configuration Utility
To access the Controller Configuration Utility:
1 When you turn on or reboot your system, press Ctrl+A to access
ARC when prompted by the following message:
Press <Ctrl><A> for Adaptec RAID Configuration Utility
2 If multiple controllers are installed, select the controller you
want to configure and press Enter.
3 From the ARC menu, select SCSISelect Utility.
The Controller Configuration and SCSI Configuration menu
options are displayed.
4 Select Controller Configuration.
You can modify the following Controller Interface Definitions:
■ Drives Write Cache — Enables or disables the write-back
cache feature of all SCSI disk drives connected to the
controller. If Disabled, the controller will disable the write-
back cache of all attached drives. If Enabled, then the
controller will enable the write-back cache of all attached
drives. If Drive Default, then the controller will not change
the write-back cache setting of any attached drives. The
default is Drive Default.
Caution: Disk drives with write-back cache enabled do
not have the benefit of battery protection and could
lose or corrupt data as a result of unexpected power
loss or drive removal.
Certain controllers may not support drives write cache. In
those cases where drives write cache is not supported,
setting the option to Enabled has no effect.
■ Runtime BIOS — Enables or disables the controller’s
runtime BIOS. The BIOS must be enabled if you want to boot
from the controller.
