Expanding Disk Capacity on Operating Array

This section describes the procedure for expanding the disk capacity on an operating array without changing the RAID level.

To extend the capacity of an array

1.    Select the Array in the list of system devices, as shown in Figure 1.

The Array Property tab appears, as shown in Figure 1.

Note: Hover the mouse over the array storage allocation bar to view the size of the array. If you have already created one or more virtual disks, they are displayed as segments in the storage allocation bar and sized proportional to their disk capacity. Hover the mouse over individual segments to view the virtual disk’s name and size.

2.    Rollover the Operation tab and select Migrate, as shown in Figure 1.

3.    The drop-down menu at the top displays the current RAID level for the array as shown in Figure 2. Do not change the RAID level as you intend to increase capacity for the current level.

4.    The available physical drives are displayed, as shown in Figure 2. Click on the specific drives to add them to the array. You may add any number of drives depending on the required array size.

5.    Click Submit, as shown in Figure 2.

You are redirected to the array properties tab where migration status is displayed, as shown in Figure 3.
