Hmm LSI's website says its a LSISAS2008 not a LSISAS2108

Are you actually using HW RAID volumns then instead of direct disks?
If so I would advice configuring the disks as passthrough.
What does pciconf -lv say?
On boot I see the following here to 2008 chip controller:-
== /var/run/dmesg.boot ==
mps0: <LSI SAS2008> port 0xe000-0xe0ff mem 0xfaf3c000-0xfaf3ffff,0xfaf40000-0xfaf7ffff irq 26 at device 0.0 on pci7
mps0: Firmware: 11.00.00.00
mps0: IOCCapabilities: 185c<ScsiTaskFull,DiagTrace,SnapBuf,EEDP,TransRetry,IR>
== pciconf -lv ==
mps0 at pci0:7:0:0: class=0x010700 card=0x30201000 chip=0x00721000 rev=0x03 hdr=0x00
vendor = 'LSI Logic (Was: Symbios Logic, NCR)'
class = mass storage
subclass = SAS
I suspect reading around that the MegaRAID cards are have SAS chips on board
but are superseed by the RAID part hence mfi vs mps
I wonder if you could flash with the IT firmware instead of IR to make it show
as mps instead of mfi?
