Using Adaptec RAID Configuration

Using the Controller Configuration Utility

To access the Controller Configuration Utility:

1When 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

2If multiple controllers are installed, select the controller you want to configure and press Enter.

3From the ARC menu, select SCSISelect Utility.

The Controller Configuration and SCSI Configuration menu options are displayed.

4Select 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.
