Restoring An Array To Its Original Controller - Compaq Smart Array 221 User Manual

Restoring an Array to Its Original
Controller
If you have moved an array from one controller to another, you can restore it to
its original controller. Figures 2-5 through 2-7 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 2-5 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.
