Symptoms

På grund af en overlappende bitmappost kan DD9800 Revision 2 muligvis medføre en SP på grund af "Spændingen er defekt", når det virkelige problem er en CPU External IERR.
Når begge hændelser (CPU External IERR og "Voltage is faulty") opstår samtidigt, er det sikkert at ignorere spændingsadvarslen og fokusere fejlfinding på, hvorfor CPU'en stødte på en CPU IERR. Du kan få flere oplysninger om fejlfinding af CPU IERR-fejl på DD9800-platforme ved at kontakte din supportudbyder for at få hjælp.

Berørte systemer:
- DD9800 Rev 2
- DDOS 5.7.x / 6.0.x / <6.1.3.0

Cause

Dette problem findes i DDOS version 5.7 , 6.0 og 6.1

Grundårsagen er, at SP-fejlbitmap overlapper hinanden, så når der sker en IERR-hændelse, viser advarselsmeddelelsen forkert "spændingen er defekt"

#define  APL_FRU_FAULT_SP_CPUMISC       (1 << 17)
#define   APL_FRU_FAILEDMAP_VOLTFAULT_SP    (1 << 17)

 

Resolution

Denne overlappende bitmap er rettet i DDOS 6.1.3.x
