Restoring An Array To Its Original Controller - Compaq 3200 Reference Manual

2-10 Guidelines for Making Changes to Current Installation
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.
