[OpenIndiana-discuss] Only one SSD detected on expander

[Scott Marcy]

FWIW, this is what Samsung tech support had to say about the SSD 840 Pro:

"The next generation Samsung SSD 840 Pro series will have WWN. The Samsung 840 Pro is aimed for customers who need to use them on servers which is why only the 840 Pro will have the WWN identifier."

Guess I'll get in line for a few and find out.

So at least kudos to Samsung there.)

It may even be that a step was "accidentally" skipped in the manufacturing process (to make quotas) and that some devices are correctly configured from the factory while others are not.
