INTRODUCTION

This section gives a brief introduction on the RAID-related background knowledge and an outlined introduction on the VIA SATA RAID Host Controller. For users wishing to install their VIA SATA RAID driver and RAID software, please refer to the Driver and RAID Software Installation section.

RAID Basics

RAID (Redundant Array of Independent Disks) is a method of combining two or more hard disk drives into one logical unit. The advantage of an array is to provide better performance or data fault tolerance. Fault tolerance is achieved through data redundant operation where if one drives fails, a mirrored copy of the data can be found on another drive. This prohibits the occurrence of operating system failure or data lost. The individual disk drives in an array are called “members”. Configuration information of member is recorded in their “reserved sector” that identifies the drive as a member. All disk members in a formed disk array are recognized as a single physical drive to the operating system.

There are usually a few methods in which hard disk drives can be combined together. The different methods referred as different RAID levels. Different

RAID levels represent different performance level, security level and implementation cost. The RAID levels which VIA VT8237 SATA RAID Controller supported are RAID 0, 1, and JBOD. Here is a brief table of these RAID levels.

RAID Level

RAID 0 (Striping)

RAID 1 (Mirroring)

JBOD (Spanning)

No. of Drives

Capacity Benefits

Number drives * Smallest size

Highest performance without data protection

Smallest size

Sum of All drives

Data protection

No data protection and performance improving, but disk capacity fully used.

RAID 0 (Striping)

Reads and writes sectors of data interleaved between multiple drives. When any disk member fails, it affects the entire array. The disk array data capacity is equal to the umber of drive members times the smallest member capacity. The striping block size can be set 4KB to 64KB. RAID 0 does not support fault tolerance.

1

RAID 1 (Mirroring)

Writes duplicate data on to a pair of drives while reads are preformed parallel. If one of the mirrored drives suffers a mechanical failure or does not respond, the remaining drive will continue to function. Due to redundancy, the drive capacity of the array is the capacity of the smallest drive.

Under a RAID 1 setup, an extra drive called “spare drive” can be attached.

Such a drive will be activated to replace a failed drive that is part of a mirrored array. Due to the fault tolerance, any one drive of RAID 1 failing does not impact the data access.

JBOD (Spanning)

A spanning disk array is equal to the sum of the all drives when the drives used are different capacities. Spanning stores data on to a drive until it is full then proceeds to store files onto the next drive in the array. When any disk member fails, the failure affects the entire array. JBOD is not a really

RAID and does not support fault tolerance.

BIOS CONFIGURATION UTILITY

Enter BIOS Configuration Utility

When the system powers on, the following information will appear on screen. Press the ‘Tab’ key to enter BIOS configuration utility.

The main interface of BIOS configuration utility is as below:

3

Create Disk Array

1. Use the arrow keys to navigate the main menu. Use the up and down

arrow keys to select the Create Array command and press <Enter> to call

out the list of creation steps.

2. Highlight the Array Mode and press <Enter>, then a list of array modes

will appear. Just highlight the target array mode that you want to create,

and press <Enter> to confirm the selection.

4

3. After selected array mode, there are two methods to create a disk array.

One method is “ Auto Setup ” another is “ Select Disk Drives ”. Auto

Setup let BIOS select the disk drives and create array automatically. Select

Disk Drives let user select the array drives by required. When using Select

Disk Drives method, the channel column will be activated. Just highlight

the target drives that you want to use and press <Enter> to select them

respectively. After all drives have been selected, press <Esc> to go back to

the creation steps menu.

4. If user selected a RAID 0 array in step 2, user also can select a block size

for the array. Use the arrow key to highlight the Block Size and press

<Enter>, then select a block size from will popup. The block size can be

selected from 4K to 64K Bytes.

5

5. Use the arrow key to highlight Start Create Process and press <Enter>.

A warning message will appear, press Y to finish the creation, or press N

to cancel the creation.

6. Please note that all existing content in the hard drive will be destroyed

after the array creation.

Delete Disk Array

A specific RAID can be deleted after it has been created. To delete a created

RAID, please use the following steps:

1. Select Delete Array in the main menu and press <Enter>.

The channel bcolumn will be activated.

2. Select the member of an array that is to be deleted and press <Enter>.

A warning message will show up, press Y to delete or press N to cancel.

Deleting a disk array will destroy all the data on the disk array except RAID 1 arrays. When a RAID 1 is deleted, the data on these two hard disk drives will be reserved and become two normal disk drives

6

Select Boot Array

User can select a disk array as boot device if user wants to boot operating system from an array. Boot disk array can be not selected if user does not boot operating system from disk array. Use the arrow key to highlight the

Select Boot Disk item then press <Enter>. The channel column will be activated. Just use arrow key to highlight the target disk array then press

<Enter>. If user select a disk array that has a boot mark and press <Enter>, then its boot setting will be canceled.

View Serial Number of Hard Drive

Highlight Serial Number View and press <Enter>. Use arrow key to select a drive, the selected drive’s serial number can be viewed in the last column. The serial number is assigned by the disk drive manufacturer.

View Array Status

Press the F1 key to show the array status on the lower screen. If there are no disk arrays then nothing will be displayed on the screen.

7

Duplicate Critical RAID 1 Array

When booting up the system, BIOS will detect if the RAID 1 array has any inconsistencies between user data and backup data. If BIOS detects any inconsistencies, the status of the disk array will be marked as critical, and

BIOS will prompt the user to duplicate the RAID 1 in order to ensure the backup data consistency with the user data.

If user selects Continue to boot , it will enable duplicating the array after booting into OS.

8

Rebuild Broken RAID 1 Array

When booting up the system, BIOS will detect if any member disk drives of

RAID has failed or is absent. If BIOS detects any disk drive failures or missing disk drives, the status of the array will be marked as broken.

If BIOS detects a broken RAID 1 array but there is a spare hard drive available for rebuilding the broken array, the spare hard drive will automatically become the mirroring drive. BIOS will show a main interface just like a duplicated RAID 1. Selecting Continue to boot enables the user to duplicate the array after booting into operating system.

9

1. Power off and Check the Failed Drive:

This item enables users to turn off the computer and replace the failed

hard drive with a good one. If users•e computer does not support APM,

the computer would need to be turned off manually. After the replacement,

users can boot into BIOS and select 3 Choose replacement drive and

rebuild to rebuild the broken array.

2. Destroy the Mirroring Relationship:

This item enables users to cancel the data mirroring relationship of the

broken array. For broken RAID 1 array, the data on the surviving disk will

remain after the destroy operation. However, Destroy the Mirroring Rela

tionship is not recommend because the data on the remaining disk will be

lost when the hard drive is used to create another RAID 1 array.

3. Choose Replacement Drive and Rebuild:

This item enables users to select an already-connected hard drive to

rebuild the broken array and replace the data to that particular hard drive.

After choosing the item, the channel column will be activated.

Highlight the target hard drive and press <Enter>, a warning message will appear. Press Y to use that hard drive to rebuild, or press N to cancel.

Please note by selecting option Y , all the data on the selected hard drive will be destroyed.

4. Continue to boot:

This item enables BIOS to skip the problem and continue booting into OS.

Warning: Deleting a disk array will destroy all the data on the disk array except RAID 1 arrays. When a RAID is deleted, the data on these two hard disk drives will still remain and become two normal disk drives.

2 4

Check All Disks

At any time, by clicking on the , the disk drives can be checked on whether they are working properly or not. After the disk check is completed, a dialog window will pop up to show the status of each disk. See picture below.

The hard disk drive must be compatible with the ATA/ATAPI-5 specification and support SMART commands, or the disk checking will fail.

2 5

View Event Log

The RAID software records important events into a log file, such as disk array creation, disk array removal, disk failure, synchronization....etc.

1. Click on to display the event log. There are three types of log items:

Information , Warning , and Error .

2 6

2. To view the details of a log item, diuble click on the row, select the row and

press <Enter> to execute the menu item Operation->View Detail .

The following dialog will appear.

Click on or to browse the next or previous log item.

3. To clear all log items, click on Operation->Clear All in the menu bar.

Note: Only the operations in the RAID software can be recorded into the log file. The operations in BIOS will not be recorded.

2 7

Verify Mirror Disk

The data on the mirror disk must be the same with its corresponding source disk to provide fault tolerance for RAID 1.

1. Select a RAID 1. Right-click on the selected RAID and a shortcut menu

will be shown. Click on Verify Mirror to verify whether the source and

mirror are identical.

2 8

2. After executing the “verify mirror” command, a dialog box will show the

verifying process. This action can paused or canceled at any time. It may

take a long time to verify the source and mirror disk if the capacity of the

RAID is large.

3. When mirror disk is not identical with the corresponding source disk, the

mirror disk will be marked with a “need-sync” flag. The icon used to

indicate this status is . A “need-sync” mirror disk should be synchro

nized as soon as possible.

2 9

Synchronize Mirror Disk

RAID 1 arrays must be synchronized when the data on the mirror disk is not identical with its corresponding source disk. Sometimes the data on the mirror disk may be newer than the data on the source disk. For example, the source disk is absent and the mirror disk runs in the tolerance mode. So the exact meaning of “Synchronize Mirror” is to make a pair of source and mirror disks contain identical data. The RAID software always marks the mirror disk with a “need-sync” icon despite the fact that the mirror disk may have the correct data.

1. Select a RAID 1 array, right-click the selected RAID and a shortcut menu

will be shown. Click on Synchronize Mirror to synchronize the source

and mirror disks.

3 0

2. After synchronization has started, a dialog box will show the process.

This action can be paused or canceled at any time.

3. An informing message will appear when the synchronization is finished.

3 1

Disk Error Detection

The RAID software will pop up an error message if a disk drive fails or missing.

3 2

Duplicate Critical RAID 1 Array

When booting up the system, the RAID utility will detect if there are any inconsistencies between the source and mirror disk drives of the RAID 1 arrays. If the software detects that a RAID 1 array containing inconsistencies, the status of the disk array will be marked as critical and the software will prompt the user to duplicate RAID 1 to make the mirror disk consistent with the corresponding source disk.

You can click Yes to synchronize now or click No to synchronize later.

After synchronization has started, a dialog box will show the process and this action can be paused or canceled at any time. If the synchronization process is cancelled, the RAID will be on the “need-sync” condition and synchronization should be proceeding again to guarantee the data consistency between sources and mirror disk drives.

A message will pop up when the synchronization process is finished.

3 3

Rebuild Broken RAID 1 Array

After booting up the system, the RAID utility will detect if any member disk drives of RAID 1 array has failed or is absent. If the RAID utility detects any disk drive failures or missing disk drives, the status of the array will be marked as broken.

If the RAID software detects a RAID 1 array being broken, the RAID software will indicate a series of steps to repair such problem.

1. A dialog box will be shown to indicate that the RAID is broken.

Click Yes to repair the array.

2. Another dialog box will pop up. If the source or mirror disk drive is un

plugged only, click Cancel to stop the rebuilding process and shut down

the system. Plug in the absent disk drive and then reboot system. If the

original disk drive is broken, plug in a new disk drive and then reboot the

system. Click Next to proceed to the next step.

3 4

3. Select a disk drive from Available Disks and click on to replace the

broken drive and then click Next .
