[OpenIndiana-discuss] Only one SSD detected on expander

[Scott Marcy]

I'm pretty sure I tried that, but now I can't be sure. I've already returned the drives and ordered the 840 Pros, which are supposed to have WWNs. If it turns out they don't, I'll give this a try before I return them, too. :-/

Thanks!
