Customer messaging policy
• A diagnostic LED only illuminates for physical processor core errors, when isolation is to a
specific IPF processor module. If there is any uncertainty about a specific processor, then the
customer is pointed to the SEL for any action, and the suspect IPF processor module CRU LED
on the System Insight Display does not illuminate.
• For configuration-type errors (for example, when no IPF processor module is installed in
processor slot 0) all of the CRU LEDs on the diagnostic LED panel illuminate for all of the IPF
processors that are missing.
• No diagnostic messages are reported for single-bit errors that are corrected in both instruction
and data caches, during CMC events to any physical processor core. Diagnostic messages
are reported for CMC events when thresholds are exceeded for single-bit errors; fatal processor
errors cause global / local MCA events.
