38 Chapter 4 Using Advanced Features of RAID Admin

Expanding an Array

You can easily add one or more available drives to an array. The drives must be on the

same controller as the array.

Expanding an array is a two-stage procedure. These stages are:

• Using the Expansion window to add one or more drives to an array

• Using the Slicing window to merge the slices in that array

Important: Only expand an array that has not been sliced previously. If you expand an

array that already has slices on it, all the data on the array will be erased when you

merge the slices in the array.

Any data on a drive will be erased when you add that drive to an array.

To expand a RAID array:

1 In the RAID Admin window, click Advanced.

2 If necessary, enter the management password and click OK.

3 Click Expansion in the Advanced window and click Continue.

4 In the Expansion window, select the array you want to expand.

This window provides brief details about each RAID level or drive when you click the

button for a RAID level or put the pointer on the picture of a drive module.

5 Select the number of drives you want to add to the array.

The controller automatically selects available drives to add to the array.

6 Click the Confirmation checkbox to confirm that you want to expand the array.

7 Click Expand Array.
