Changing a drive in predictable failure state

On the fly can result in lost the whole array in the worst case. => data

omconfig storage adisk action=remove controller=id
omconfig storage adisk action=offline controller=id

One of these steps should be done to remove the disk from the array. I
use generally the offline task.

I have pulled out a drive on the fly, inserted another and had the array
rebuild the VD just fine. I believe Dell discourage that but it should
work. ;-)
