1.
Remove and reinsert the faulty hard drive.
2.
Swap the hard drive with one from another slot or with a known good spare.
3.
Remove and reinstall the hard drive backplane. Verify that connectors are fully engaged.
4.
Replace the hard drive backplane.
5.
Re-seat cables.
Console issues
Console issues during installations can be caused by faulty interconnections. If you are experiencing
monitor, keyboard, or mouse issues:
1.
View the monitor controls. Adjust contrast and brightness as required.
2.
Inspect all power and interconnecting cables. Verify that all console connectors are fully
engaged.
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
All of the processor and memory controller functions are integrated into the processor. DIMMs
reside on the memory risers, 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
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
