Point of using ZFS is that you do not need to be tighten to your hardware.
Treating all disks as JBOD and letting ZFS handle them is preferred way.

Problem obviously is within that hardware controller.
If ZFS was handling disks (and managing disks pool) it would most
certainly boot like nothing happened.

Some people tend to use both ZFS handling volumes from hardware RAID and
hardware RAID making those volumes out of groups of disks. (to use
benefits of hardware caching etc),
just same could be done with ZFS without being tight to hardware issues,
but eather way ZFS should be presented with multiple disks/volumes, and
making pool out of them, so he can do something clever with he's
included volume management.
