D-16 HP StorageWorks Modular Smart Array 500 System User Guide

The expansion process is illustrated in the following figure, where the original array

(containing data) is shown with a dashed border, and the newly added drives are

shown unshaded (they contain no data). The array controller redistributes the original

logical drive over the enlarged array, using the same fault tolerance method. The

unused capacity on the new (enlarged) array can then be used to create an additional

logical drive, with a different fault tolerance setting if necessary. Alternatively, the

extra capacity can be used to increase the size of the original logical drive (capacity

extension).

If you are expanding an array that has several logical drives, data is redistributed one

logical drive at a time. Newly created logical drives are not available until capacity

expansion is complete.
