Replacing, moving, or adding hard drives 29

The expansion process is illustrated in the following figure, in which the original array (containing data) is

shown with a dashed border and the newly added drives (containing no data) are shown unshaded. The

array controller adds the new drives to the array and redistributes the original logical drives over the

enlarged array one logical drive at a time. This process liberates some storage capacity on each of the

physical drives in the array. During this procedure, the logical drives each keep the same fault-tolerance

method in the enlarged array that they had in the smaller array.

When the expansion process has finished, you can use the liberated storage capacity on the enlarged

array to create new logical drives. Alternatively, you can enlarge one of the original logical drives. This

latter process is called logical drive capacity extension and is also carried out using ACU.
