A warning appears if you select an array that has partitions. Do not

Adding and Deleting Spares
Dedicated spare disks (spares) are an important data protection and
real-time recovery feature of RAID 1 arrays (RAID 0 arrays do not
support spares). Up to two dedicated spares can be defined for each
array. If a disk in an array fails while the computer is running, a spare is
activated immediately to take its place. The array software
automatically reconstructs the necessary data on the new disk, and
array operation continues uninterrupted.
Adding a Dedicated Spare
When you create an array you have the option of adding one or two
dedicated spares. You can also add dedicated spares to an existing
array at a later time. You cannot add dedicated spares to an array if:
The array already has two dedicated spares
•
The remaining single disks are not at least as large as the smallest
•
