This list relates the AIX logical name of all resources to location code. Look for the AIX logical name
that you recorded in the first step and read the location code of the resource. You can then determine
the physical location of the resource by flashing the FRU identify LED (see “FRU Identify LEDs” on
page 27) that corresponds to the location code.
