4. Available disk drives appear in the listing. Click

Add

to add the disk drive it to the array.

The RAID array is rebuilt for the added or changed redundant disk drive. While the rebuild
continues, the array can still be used. After the rebuild process completes, the disk becomes part
of the redundant storage. You can monitor the progress of the rebuild through the
