Storage Manager

NOTE If a drive fails during expansion, the expansion will complete

successfully. However, the new, larger array will be in a

degraded state until the problem is fixed.

If there is a Hot Spare associated with the array, the degraded

array is rebuilt using the Hot Spare. If there is no Hot Spare,

replace the defective drive, and start a rebuild of the array.

• Each new drive added to an array must be at least equal to the

capacity of the smallest capacity drive already in the array.

In any RAID configuration, the drive with the least capacity in the

array determines the usable capacity of all the drives in the array.

Therefore, there is no advantage in adding a drive with a capacity

larger than the smallest capacity drive already in the array.

Expanding an Array Group

IMPORTANT

DPT recommends that you backup your data before performing an operation

that affects the configuration of a disk array. Do not power off the host system

while the expansion operation is running.

To expand an existing Array Group, do the following:

1. Connect the additional drives to the peripheral bus and power-on

the drives. Refer to the Chapter 3, “Configuration and Installation”

if necessary.

NOTE If the drives are not in hot-pluggable carriers, power down the

system before adding drives to the peripheral bus.

2. Start Storage Manager and click Switch View to change to the

Logical Configuration View.

3. Select the Array Group to which you want to add drives by clicking

the corresponding RAID 0 or RAID 5 icon.

4. Click Expand Array Group.

5. Mark the drives to be added to the array by clicking on them. A

green check mark indicates that a drive is selected.

6. Click Include Drive. This will cause the marked drives to join the

existing Array Group. The drives to be added are now marked New.
