Figure 41 provides a graphical illustration of the controller replacement process
for DRM configurations.
Caution: In DRM configurations, use a factory-provided controller
(configuration-free) or one that is reset with the Port #5 button reset action to
avoid mirrored cache corruption on the replacement controller or recursive
bugchecks (OCP code 25) on both initiator controllers.

Note: Pulling Port #2 Fibre cable on the initiator controller inhibits the chance of
invalid cache conditions at the initiator site during target controller replacement
actions.
