If you do not get the above Alert Level 7 (IPMI) event, but get another high level alert, replace
the server blade.
8. Add at least one rank of memory DIMMs.
9. Enter the DF command. The following displays:
Display FRU Information Menu:
S - Specific FRU
A - All available FRUs
V - Display Mode: Text
10. Enter S to show the FRU IDs. The following displays (one rank of DIMMs installed):
FRU IDs:
--------
0001-Comm Module 0002-Disk Backplane 0003- Mezzanine Board
0128-DIMM0A 0129-DIMM0B 0000-Motherboard
If you do not see all of the above FRU IDs then concentrate on the missing FRU ID(s). The
following alert (IPMI) event displays for this action, as read from the SEL:
Log Entry 3: Dec 2005 21:50:43
Alert Level 7: Fatal
Keyword: Type-02 257100 2453760
Missing FRU device - Processor 0
Logged by: Baseboard Management Controller,
Sensor: Entity Presence
0x2041CB3DB3020040 FF2080711525030
If you do show the Alert level 7 “Missing FRU device - Processor 0”, continue to the next step.
11. Insert a processor into processor slot 0. When you add the processor and turn on server
power, the cooling fans should turn on and stay on, and the DF and S command output
should look something like this:
FRU IDs:
--------
0032-Processor 0 0036-Processor 0 RAM 0001-Comm Module
0002-Disk Backplane 0003- Mezzanine Board 0128-DIMM0A
0129-DIMM0B 0000-Motherboard
If the installed FRUs are all functional, the server should initiate POST on all processors. Observe
the system console output through “Live Events” to ensure that POST initiates and completes
without error.
If POST does not start after a few seconds, suspect some sort of system board or processor
problem. Typical problems show up in the SEL or FWP. If the IPMI event logs do not point to
a root cause, escalate to bring in expert assistance.
Troubleshooting Processors/Memory/SBA
All of the processor, memory controller, DIMMs, and SBA (I/O rope controller) functions reside
on the server blade FRU. This section discusses the roles of physical processors and physical memory
ranks.
Troubleshooting Processors
Each server blade supports 1 or 2 Intel processors. The Intel dual-core processors have two logical
processors per physical processor. This means you can have four processor cores when two physical
processors are installed into a server blade.
Each physical processor core contains logic to support two physical threads. The operating system
kernel attaches one or more software processes to each available thread, so in multiple processor
server blades, having more threads means all software processes are launched and issued more
rapidly.
