[OpenIndiana-discuss] Only one SSD detected on expander

I am returning the 4 drives I planned to use in the expanders, but will keep the two I'm using as my mirrored boot pool.

My intention was to use these are ZIL and L2ARC drives, so I can do without them for now. I've had very good luck with these Samsung drives in non-SAS usages—quite a bit more reliable in my (admittedly quite limited) experience than the SanForce-based SSDs.

Here's hoping they've fixed this on the 840 Pro models.

Thank you all for your help. I learned something new and now understand why it doesn't work. :-)

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.
