4. Secure the controller with the system's retaining bracket. 5. Attach the activity light cable to the activity light connector on the Adaptec U320 SCSI RAID 0 or 1 controller and the motherboard if needed. Make sure that pin 1 on the connector is aligned with pin 1 of the cable.
The Adaptec U320 SCSI RAID 0 or 1 is preset to ID 7 for each channel and should not be changed. If you boot from a SCSI hard disk, make sure the hard disk SCSI ID is set to 0. (Most SCSI hard disks are preset to SCSI ID 0 at the factory.) The SCSI IDs for internal devices are usually set with jumpers; SCSI IDs for external devices are usually set with a switch on the back of the device. SCSI Termination Proper termination of channels used with SCSI devices is critical in having the system work properly.
Voltage Differential (HVD) devices is not suggested. HVD devices will adversely affect other devices attached to the same channel and could cause a working Ultra320 channel to become nonfunctional, due to distance constraints inherent in using some of these older devices.
0 or 1. 2. Connect the other end of the cable to a SCSI connector on the back of an external device. If you are installing only one external device, terminate the device and skip to "step 4". 3. Connect the other external SCSI devices by linking each device to the previous one, as shown below. Terminate only the device at the end of the chain. 4. Connect power cables to all external device(s) and to the system.

Optimizing Performance RAID Performance Characteristics 0 Highest Read and Write Performance, no fault tolerance. 1 Good Read Performance and Lower Write Performance.
NOTICE: It is recommended that you not use the unused portion of the global hot spare as it may result in a single drive RAID 1. Drive Roaming Drive roaming enables a RAID volume to be moved from one controller to another controller without interruption. Each drive has a unique ID which can be physically changed by setting a jumper to allow drive roaming. Formatting Most drives can re-assign sectors to recover from failures.
Enter the BIOS utility by pressing . From the device menu that appears, select a channel and press . The BIOS Configuration Utility menu displays the following options: Configure/View SCSI Controller Settings Configure/View HostRAID Settings SCSI Disk Utilities NOTE: To select an option from this menu or from any of the menus, move the cursor to the option with the Up/Down arrow keys and press .

SCSI Controller ID—(Default: 7) Sets the SCSI ID for the SCSI card. The Adaptec U320 SCSI RAID 0 or 1 is set at 7, which gives it the highest priority on the SCSI bus. We recommend that you do not change this setting. SCSI Controller Parity—(Default: Enabled) SCSI cards perform parity checking to verify the accuracy of data transfer on the SCSI bus. Most currently available SCSI devices support parity checking. However, if a device on the SCSI bus does not support parity checking, disable this option.
BIOS can use this setting to set the starting point for negotiating the synchronous data transfer rate to a slower speed. For example, in the case of Wide transfers, if the Sync Transfer Rate is set to: 320, 160, or 80—The BIOS negotiates at 80 MB/sec. 40 or lower—The BIOS negotiates at the Sync Transfer Rate setting. Eventually, the BIOS completes negotiation. Later, the device driver takes over. The device driver uses this setting as a starting point for negotiating data transfers.
BIOS does not control the SCSI device and device driver software is required. The BIOS can support up to eight INT 13 devices without an additional device driver. Advanced Configuration Options NOTICE: Do not change the Advanced Configuration Options unless absolutely necessary and you thoroughly understand the consequences of the change.
according to the setting of the Send Start Unit Command. SCSISelect remains available if needed. The following options have no effect if the SCSI card BIOS is disabled. (The SCSI card BIOS is normally enabled by default.) Domain Validation—(Default: Enabled) Determines the optimal transfer rate for each device on the SCSI bus and sets transfer rates accordingly. When enabled, this option is available if it is implemented in the device drivers. However, this option is not supported by the BIOS.
ON—Cache is set to Enable state OFF—Cache is set to Disable state Array Setup With SCSISelect, you can create arrays when you select the HostRAID® option. Creating Arrays Before creating the array, make sure the disks for the array are connected and installed in your system, then follow these steps: 1. Start SCSISelect . 2. Select Configure/View HostRAID Settings. 3. From the Main menu, press C to create a RAID array. NOTE: You must have at least two hard drives to create an array.
message appears: Do you want to make this array bootable? 5. Select Yes if you want to make the array bootable. The following message appears: Create Array? 6. Select Yes. The following message appears: Are you sure? 7. Select Yes and press to create a RAID 0 array. After your array is created, you will automatically return to the Main menu. Creating RAID 1 Arrays There are two ways to create a RAID 1 array.
Are you sure? 6. Select Yes and press to create a RAID 1 array. If you select No, the RAID creation will terminate and you will return to the Main menu. After your array is created, the progress bar will appear showing the percentage completed in the create process. If for any reason you want to stop the build process and return to the Main menu, press . You may continue the build process by selecting the Rebuild function later.
With RAID 1 you have the option to create a maximum of 2 spare drives. You can create a spare before you define your RAID, or you can add a spare later to an existing RAID 1 array. To create a spare prior to defining a RAID, or add to an existing RAID 1 array: 1. From the Main menu, press S to add a spare. The following options appear: Add Spare Delete Spare (only available if a spare already exists) 2. Select a drive and press .
To verify data integrity, your RAID 1 must be at Optimal status. To verify data integrity: 1. From the Main menu, select array, press , then press V. 2. Select Yes and press . If you select No, you will return to the Main menu. NOTE: During the Verify process, you can stop the Verify by pressing Esc. You will get a pop-up window displaying Stop Verify? If you select Yes, you will return to the Main menu. HostRAID will set a check point when you exit Verify.
HostRAID has a check point feature that enables you to exit the SCSISelect utility when an operation (for example, Verify, or Rebuild) is in progress. The HostRAID driver will continue the operation where SCSISelect left off, and SCSISelect will continue the operation where the HostRAID driver left off, if an operation was started from the driver. Deleting Arrays NOTICE: Deleting an array will result in the loss of all data on the array. To delete an array: 1.
1. Start SCSISelect. See "Starting and Exiting SCSISelect". SCSISelect detects all Dell SCSI cards and displays the model number, channel letter, slot number, and PCI address for each SCSI card and channel. 2.
