Symptoms
While creating a dumpfile (hpost -D), we can see an error in the post logs pointing to the seeproms of the Ecache for processors P0 and P1:
Error reading E$Dimm SBxx/P[0,1]/E[0,1] seeprom
Example (first part of post logfile):

Cause
This usually happens because the CPU/Memory Uniboard has only two cpus installed (processors in slots P2 and P3).
Solution
Check the prtfru output available in the explorer for the main SC (explorer_dir/fru/prtfru_-x.out), looking for the "Segment ID" of the impacted board.
For instance:
SEGMENT: ID
/SG_CPUSpeedR
/SG_CPUSpeedR/CPU0_SerialNum: 0000000000000000000000000000000000000000000000000000000000000000
/SG_CPUSpeedR/CPU0_Speed: 0
/SG_CPUSpeedR/CPU1_SerialNum: 0000000000000000000000000000000000000000000000000000000000000000
/SG_CPUSpeedR/CPU1_Speed: 0
/SG_CPUSpeedR/CPU2_SerialNum: 0000000000000000000000010010111110100110000001100101010010101100
/SG_CPUSpeedR/CPU2_Speed: 1200
/SG_CPUSpeedR/CPU3_SerialNum: 0000000000000000000000010010111110100110000001100101010010101100
/SG_CPUSpeedR/CPU3_Speed: 1200
This confirms that this is a 2-cpu board (2 x 1200MHz in this case).
If the prtfru output does not confirm that the impacted board is a 2-cpu board, then other MOS documents must be checked to determine the root cause, and eventually a Service Request needs to be opened.
This behavior has to do with the order of probing.
Hpost checks the E$ seeprom before checking the processor presence.
Conclusion:
These messages are usually harmless and can be safely ignored; they only occur while creating a dumpfile via a 'hpost -D'.
Additional InformationThis error during the hpost may be associated with the error reported in the platform messages file (explorer_dir/sf15k/adm/platform/messages) by frad (the FRU access daemon) failing to access the SEEPROM.
