A Word About Auto Cloning
When a controller is hot swapped in a dual controller array, an Auto Clone
process copies firmware from the existing controller to the new controller. The
cloning process occurs even if the new controller has a newer revision of
firmware. When the Auto Clone process has completed, a Fast Reset process
mirrors the memory from the existing controller to the new controller.
Note The Auto Clone process will not work if the replacement
controller has HP14 or later firmware and the existing controller
has HP13 or earlier firmware. In this situation, the existing
controller cannot overwrite the HP14 or later firmware on the
replacement. Make sure the controller has HP13 or earlier
firmware on it before using it as a replacement.
Removing an Array Controller
(HP Service Personnel Only)
The process of removing a controller is influenced by factors such the array
configuration (single or dual controller) and by whether the operating system
supports controller failover. The various task flows are shown in Figure 42.
