Once you start expanding array capacity, you cannot stop it. The

Expand function may take an hour or more to complete, depending on the

array type, array size, drive speed, utility priority, and other processes

running on the EF2800.

To expand an array:

1. From SAM, select Manage EF2800 > Disk Array Config > Expand

Array. The Expand Array page displays with a list of existing

arrays and available drives.

2. Select the array you want to expand.

3. Select one or more drives you want to use to expand the array.

4. Click Expand This Array.

Expansion begins and the percentage completed displays. You can

perform other functions during the expansion. To check the progress of

the expansion, select Manage EF2800 > Disk Array Config > Array Utility

Progress or any item from the Disk Array Config menu. The status of the

expansion displays in the list of arrays.
