If you do not find the error code there, go to the Fast
Path MAP in the Eserver pSeries Diagnostic Information
for Multiple Bus Systems.
Add 101- to the left of the three digits to create an SRN.
Go to Eserver pSeries Diagnostic Information for
Multiple Bus Systems.
If there is a location code displayed under the 3-digit error
code, then look at location to see if it matches failing
component that the SRN pointed to. If they do not match,
perform the action from Diagnostic Information for
Multiple Bus System first. If the problem still exists, then
replace the failing component from that location code.
