Appendix C: Using the ARC Utility 71

The ACU allows you to use drives of different sizes in a RAID 1 or RAID 0. However, during a build operation, only the smaller drive can be selected as the source drive.

When migrating from single volume to RAID 0, migrating from a larger drive to a smaller drive is allowed. However, the destination drive must be at least half the capacity of the source drive.

It is not recommend that you migrate or build an array on Windows dynamic disks (volumes), as it will result in data loss.

5When you are finished, press Done.

Managing Arrays

Select the Manage Arrays option to perform these tasks:

Rebuilding Arrays

Note: Rebuilding applies to Fault Tolerant arrays (RAID 1) only.

By replacing a failed drive of a RAID 1 array with a new drive, you can rebuild to get the array to Optimal status and assume fault tolerance. You can perform a rebuild in the following ways:

Note: If no spare exists and a hard disk drive fails, you need to create a spare before you can rebuild an array. See Adding/Deleting Hot Spares on page 72 before continuing your rebuild.

System Shutdown Rebuild

You can power off the computer and replace the failed drive with a new one (of equal or greater capacity). When the system is booted, you can assign the new drive as a spare, and this will start the Rebuild task. All the data from the good drive is copied to the new one, and the original RAID 1 array is recreated.

Manual Rebuild

a From the Main Menu, select Manage Arrays. From the List of Arrays, select the array you want to rebuild.

b Press Ctrl+R to rebuild.

Viewing Array Properties

To view the properties of an existing array:

1From the ACU menu, select Manage Arrays.

2From the List of Arrays dialog box, select the array you want to view, then press Enter.

The Array Properties dialog box appears, showing detailed information on the array. The physical disks associated with the array are displayed here.

3Press Esc to return to the previous menu.
