Location Codes
A location code is used to physically locate a failing device or unit. The location code is
displayed along with the service request number (SRN) when the diagnostic programs
isolate a failure. If the location code is not known, you can run the Display Previous
Diagnostic Results service aid to display the results of the last time the diagnostic programs
were run.
For more information about the location codes used in the base unit or the expansion unit,
see “Locating a Micro Channel Adapter” on page 4-3 and “Locating a Disk or Media Drive”
on page 4-4.
