I assume that you have tried to use the H700 as a "JBOD" card, defining logical volume for each hard disk. The problem is: that gorgeous, fantastic, masterful, Nobel award candidate card, has a wonderful behavior in that case. If you extract one of the disks, the logical volume associated to it is invalidated. So, you insert a replacement disk, and the card refuses to recognize the volume. What is even worse, in order to recover it's mandatory to reboot the complete system *AND* go through the RAID configuration utility. That's the problem. The card refuses to work as a simple disk controller without frills, and the frills get in the way. To summarize: it isn't FreeBSD's fault, no matter which version you use. It's a "feature" coming directly from the geniuses who designed the card.
