Use this option to consolidate all Free Capacity on a selected Array so that additional logical drives can be created from the maximum amount of free capacity. A fragmented Array can result from the deletion of logical drives or from not using the entire available free capacity in a Free Capacity node during logical drive creation.
Example: You have two logical drives, "New York" and "Dallas" of 2 GB each. You would like to create a new logical drive, "Chicago" of 2 GB in the same array. There is 2 GB of space available in the array, but it is split between two Free Capacity nodes that are not contiguous and cannot be organized into a single logical drive.
In order to create a new logical drive "Chicago" of 2 GB, you must first defragment the array so that the space in the two Free Capacity nodes is contiguous.
Important:
How to Defragment an Array
1 | Select an array in the Logical View, then select either the Array >> Defragment pull-down menu option, or Defragment from the right-mouse pop-up menu. Result: The Confirm Defragment dialog box is displayed. |
2 | Select Yes. Result: All free data blocks on the Free Capacity nodes are consolidated into one Free Capacity node containing a larger set of contiguous data blocks. The Logical View is updated to display the larger, single Free Capacity node. You can select this Free Capacity node for logical drive creation. |
