It is generally strongly advised to use SATA disks on SATA controllers 
and SAS disks on SAS controllers. And to use controller that can do JBOD.

Also, using SAS to SATA multipliers or using port multipliers at all is 
strongly disadvised too,
because it is usually cheap logic in it, that can go crazy and disk is 
not under direct control of the controller..

Also what OI/illumos is that, because I was reading long ago there were 
some bugs solved in illumos for mpt_sas.

First two issues could be hardware problems, and such config is usually 
unsupportable (I know it is not on Smartos), third issue could be seen 
further.
