v Severe = S
v Warning = W
v Informational = I
I.11002
[I.11002] A processor mismatch has
been detected between one or more
processors in the system.
Explanation: One or More Mismatched Processors
Detected
Severity: Error
User response: Complete the following steps:
1.
This message could occur with messages about
other Processor configuration problems. Resolve
those messages first.
2.
If the problem persists, ensure that matching
processors are installed (i.e., matching option part
numbers, etc)
3.
Verify that the Processor's are installed in the
correct sockets according to the service information
for this product. If not, correct that problem.
4.
Check IBM support site for an applicable service
bulletin or firmware update that applies to this
Processor error.
5.
(Trained Service technician only) Replace
mismatching processor. Inspect Processor socket
and replace the system board first if socket is
damaged.

[I.18005] A discrepancy has been
detected in the number of cores
reported by one or more processor
packages within the system.
Explanation: Processors have mismatched number of
cores
Severity: Error
User response: Complete the following steps:
1.
If this is a newly installed option, ensure that
matching Processors are installed in the correct
Processor sockets according to the service
information for this product.
2.
Check IBM support site for an applicable service
bulletin that applies to this Processor error.
3.
(Trained Service technician only) Replace
Processor. Inspect Processor socket and replace
the system board first if socket is damaged.
I.18006
[I.18006] A mismatch between the
maximum allowed QPI link speed has
been detected for one or more
processor packages.
Explanation: Processors have mismatched QPI
Speed
Severity: Error
User response: Complete the following steps:
1.
If this is a newly installed option, ensure that
matching Processor CPUs are installed in the
correct ProcessorCPU sockets according to the
service information for this product
2.
Check IBM support site for an applicable retain
tipservice bulletin or firmware update that applies to
this Processor error.
3.
(Trained Service technician only) Replace
Processor. Inspect Processor socket and replace
the system board first if socket is damaged.

[I.18007] A power segment mismatch
has been detected for one or more
processor packages.
Explanation: Processors have mismatched Power
Segments
Severity: Error
User response: Complete the following steps:
1.
Processors installed do not have the same power
requirements
2.
Ensure that all Processors have matching power
requirements (such as 65, 95, or 130 Watts)
3.
If power requirements match, check IBM support
site for an applicable service bulletin or firmware
update that applies to this Processor error.
4.
(Trained Service technician only) Replace
Processor. Inspect Processor socket and replace
the system board first if socket is damaged
