The problem is that the OS can't see the RAID, only the 2 separate drives. As I also had problems with Ubuntu Linux recognizing RAID1 on an almost twin board, but with 2 SATA disks instead of SAS, I asked their support forum. Someone there suggested [*] that ESB2 controller used by Intel is software based, and that I must use software RAID to make use of it. I'm not sure if I should do the same with FreeBSD/SAS array too? Maybe there's a ready to go driver? Thanks. [*] http://ubuntuforums.org/showthread.php?p=3329522#post3329522
