You can create an array anytime. You can create arrays from either SM A or SM B. Arrays you create
from one SM are not visible through the RS-232 or Ethernet port of the other SM. However, all unused
disk drives connected to all LRC I/O modules and all pool spares are available to both SMs.
The maximum size for any array is 2 TB.
