Use the Array >> Defragment option to consolidate all free capacity
You have two logical drives, "Accounting" and "Human Resources" of 2 GB each. You would like to create a new logical drive, "Marketing" of 2 GB in the same array. The logical drive group has 2 GB of space available, but it is split between two non-contiguous Free Capacity nodes, which cannot be organized into a single logical drive.
In order to create a new logical drive "Marketing" of 2 GB, you first must defragment the array so that the space in the two Free Capacity nodes is contiguous.
In the previous example, Array 1 contained two Free Capacity nodes of 1 GB each . A Defragment Array operation on this array results in a single Free Capacity node of 2 GB.
