!Caution:

●

●

●

If the drive is used in an array, you may not be able to use the array again. Do not configure a drive that is part of a boot array. To determine which drives are associated with a particular array, see Viewing Array Properties on page 55.

The partition table on the disk will be deleted when deleting a simple volume.

Arrays can be created using simple volume. However, existing partitions in the simple volume would be erased.

Note: Configuring disk drives makes a simple volume. A simple volume can be managed like normal arrays by using the Manage Arrays option on your Main menu.

To configure drives:

1From the menu, select Configure Drives.

2Use the up and down arrow keys to highlight the disk you wish to configure, then press Insert.

3Repeat Step 2 if you want to add another drive to be configured.
