Not sure about that specific controller, but I do have a Fujitsu
rebranded "RAID Ctrl SAS onboard 256MB iTBBU LSI" that works pretty good
on my FreeBSD 6.2 box with the mfi driver.
Getting the megacli tool took some effort as it involves having Linux
emulation running but it's now working fine. I wouldn't dare to use it
for write operations as I remember it freezing the box just after
upgrading to amd64 (it was working good on i386).
Cheers
