3. Verify that all iLO 3 MP board connectors are fully engaged.
4. Exercise the appropriate self-test features of the console software.
Troubleshooting the processor and memory
Cause
All of the processor and memory controller functions are integrated into the processor. DIMMs reside on
the memory expansion boards, and PCIe bus controller chips reside on the I/O riser and the system
board. This section discusses the roles of logical processors, and physical memory ranks.
Troubleshooting the server processor
Cause
The server supports both dual-core and quad-core processors. Each server supports one or two
processor modules. The dual-core processor modules contain two individual processor cores. When two
processor modules are installed in the server, the server contains four physical processors.
Furthermore, each physical processor core contains logic to support two physical threads. When two
dual-core processor modules are installed and enabled in the server, the server supports up to eight
threads, or the equivalent of eight logical processors.
Processor load order
For a minimally loaded server, one processor module must be installed in processor socket 0 on the
system board, and the threads must be enabled by user actions. Additional processor modules of the
same revision are installed in processor socket 1 for the server.
Processor module behaviors
Local MCA events can cause the physical processor core and one or both of the logical processors within
that processor module to fail while all other physical and their logical processors continue operating.
Double-bit data cache errors in any physical processor core causes a Global MCA event, which, in turn,
causes all logical and physical processors in the server to fail and reboot the operating system.
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.
