The drive order issue is likely to be persistent mapping.
It can be disabled using lsiutil.
I found it was enabled by default on early cards, and disabled on later
ones, but changing the firmware doesn't change the origional setting.
What model are the disks ?
Did the origional system also use expanders ?
