3.5.4Creating a Disk Array

1.Select Create/Delete Array from the Main Menu.

2.Select Create Disk Array from the Create/Delete Array menu and press Enter.

3.Using the Enter key, select each drive you want included in the array you are now defining. The devices will be highlighted as they are selected and the status changes from RDY to ONL (online). Also the array ID, (A for the first one, then B and so on) appears behind the drives that make up the array.

4.Press Esc to validate.

Now that an array has been defined, it is necessary to create the logical drives on this array. Logical drive definitions for created arrays must be done before exiting the Create/Delete array menu.

Notes:

1.Up to four arrays can be defined per controller.

2.An array can be defined across the two channels of one controller.

3.You cannot define an array across two controllers.

4.For maximum performance and configuration flexibility, all installed drives should be configured into a single-disk array. Where data separation is desired, use separate logical drives on the same disk array. Each of these logical drives will appear as a separate physical disk to software programs like FDISK, and may be further divided into logical partitions. With this approach, if additional physical drives are added at a later date, they can be easily added as a second array without reconfiguring the original drives.
