Restoring an Array to Its Original
Controller
If you moved an array from one controller to another, you can restore it to its
original controller. Figures 2-3 through 2-5 show the consecutive configurations
required to restore an array to its original controller (or to a replaced controller
in the event of controller failure). Figure 2-4 shows the consolidated
configuration that includes Array A with drive IDs 0 through 3 and Array B
with drive IDs 4 and 5. Moving Array B back to Controller 2 creates an interim
four-array state, with Array B on Controller 1 and Array A on Controller 2
appearing as failed. Running the Array Configuration Utility removes the failed
arrays and restores the original two-array configuration.
