It is possible that all devices show up as having the same WWN, thus the illumos driver cannot tell them apart, and assumes they are one and the same. I've seen this with SSDs from various manufacturers, but only for "consumer" drives. The manufacturer's response was that those SSDs were supported only one per system, and where you needed more than one you had to go with the enterprise version.
