Hello.
There one trick with mptsas driver from recent kernel. Since this is
unofficial, there NO WARRANTY big warning. I not checked for already existing
RAID with data only on just created RAID. Before any actions on actual data
perform backup first!

Turns out, some LSI / Symbios Logic fakeraid cards can be recognized my mptsas
with additional pciids. All you need is find pciids for you card. My card is

lspci -nn | grep LSI
08:00.0 SCSI storage controller [0100]: LSI Logic / Symbios Logic M1064E
MegaRAID SAS [1000:0057] (rev 04)

Where [1000:0057] is PCI ID. Next you need do follow:

echo "1000 0057" > /sys/bus/pci/drivers/mptsas/new_id

Add this row to /etc/rc.conf or somewhere else for applying to next boot.

If all goes right, you physical disks will be appear in system (check dmesg).
For RAID capabilities you need to install mdadm. It autodetects partitions as
/dev/mdX:

# cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4]
[raid10]
md126 : active raid1 sde[1] sdd[0]
      142577664 blocks super external:/md127/0 [2/2] [UU]
      [=======>.............]  resync = 39.3% (56174464/142577664)
finish=1351.1min speed=1065K/sec
