The selected drive changes from READY to ONLINE A[array number]-[drive number]. For example, ONLINE A2-3 means array 2 with hard drive 3.
4. Add physical drives to the current array as desired.

NOTICE: Selecting New Configuration erases the existing configuration information on the selected controller. To use the spanning feature and keep
the existing configuration, use View/Add Configuration.
NOTE: Try to use drives of the same capacity in a specific array. If you use drives with different capacities in an array, all drives in the array are
treated as if they have the capacity of the smallest drive in the array.
