Troubleshooting processors
Processor module behaviors
All physical processors become functional after blade power is applied. Each processor is in a
race to fetch their instructions from their processor instruction and data caches to complete early
self test and rendezvous.
Double-bit data cache errors in any physical processor core can cause a local MCA event, which
can have one of the following results:
•
The entire system crashes.
•
The failure is corrected and the processor is restarted.
•
The failure is corrected, but the processor is disabled if it has experienced a local MCA within
a certain time span.
IMPORTANT:
L4 cache errors are the result of blade failure.
Firmware
There are three different firmware systems on Superdome 2:
•
System firmware bundle.
•
IO firmware (PCIe and LOM)
•
Interconnect module firmware.
All firmware systems can be updated.
System firmware
The Superdome 2 complex system firmware bundle includes firmware for complex components
including:
•
Server blade firmware (not including LOMs)
•
Partition firmware for each server blade
•
OA firmware
•
Manageability module firmware, including GPSMs and XFMs
•
Compute enclosure firmware
•
IOX enclosure firmware
