258 IBM System Storage DS3500: Introduction and Implementation Guide
The storage capacity of a standard logical drive cannot be increased if:
One or more hot spare drives are in use in the array that it resides on.
The logical drive has
Non-Optimal status.
Any logical drive in the array is in any state of modification.
The controller that owns this logical drive is in the process of adding capacity to another
logical drive (each controller can add capacity to only one logical drive at a time).
No free capacity exists in the array and no unconfigured capacity (in the form of drives) is
available to be added to the array.
To increase the logical drive capacity:
1. Highlight the logical drive to be expanded, right-click and select Increase Capacity. First,
a window with instructions (Figure 9-34) opens.
Figure 9-34 Dynamic logical drive expansion
2. Select OK and in the Increase Logical Drive Capacity window (Figure 9-35 on page 259),
enter the amount of space by which the logical drive will be enlarged.
In the top part of the window, the current size of the logical drive and the available free
capacity in the array is displayed. If no free configured space is available, but there are
unassigned drives, these can be added from this same window by clicking Add Drives before
proceeding to enlarge the logical drive. This will perform the same process described in 9.3.3,
“Add Free Capacity (Drive)” on page 236.
