Hi Jerry,

Couple of things that might help you troubleshoot your Intel SASUC8I HBA:

1. Are you seeing all the 8 devices in the BIOS for the card?
2. If yes, do other operating systems (say a Linux LiveCD) see all the disks 
3. Is there any difference between the disks (e.g. four 2TB Seagate SATA2 and 
four 2TB Seagate SATA3)?
4. Can you double check which four disks are showing up? If you swap the SAS 
cables is it the same four?
Check by printing SAS WWNs of your devices: 
#prtconf -v |grep -A 1 wwn |grep value

If only OI is missing the extra disks (yes to #1 and #2) then a firmware update 
might help.  Since that intel card is just a rebadge of the LSI 3801E as an 
alternative to just updating to the newest Intel IT/IR firmware, you also have 
the option of flashing the LSI IT firmware which is optimal for use with ZFS 
(since you don't need any integrated RAID), it should work fine with whatever 
firmware Intel provides though.
