EPUB_PRC_EIBUS_ERROR isolation procedure

A bus error occurred.
1. Use the ipmitool command to examine system event logs (SELs).
v To list SELs by using an in-band network, use the following command:
ipmitool sel elist
v To list SELs remotely over the LAN, use the following command:
ipmitool -I lanplus -U <username> -P <password> -H <BMC IP addres or BMC hostname> sel elist
2. Identify all SELs with the value OEM record df and Correctable Machine Check Error or Transition
to Non-recoverable in the description. Did you find one or more SELs with the value OEM record df
and Correctable Machine Check Error or Transition to Non-recoverable in the description?
If Then
Yes: Continue with the next step.
No: Go to "Contacting IBM service and support" on page 71. This ends the procedure.
3. For each of the SELs that you identified in step 2, determine the sensor name that is associated with
each SEL. Replace the following items, one at a time, until the problem is resolved:
Note: If your system is an 8001-12C or 8005-12N, go to "8001-12C or 8005-12N locations" on page 73
to identify the physical location and removal and replacement procedure. If your system is an
8001-22C or 8005-22N, go to "8001-22C or 8005-22N locations" on page 87 to identify the physical
location and removal and replacement procedure.
v If the sensor name is CPU Func 1 or CPU Core Func x, where x is 1 - 12, replace system processor
CPU 1.
v If the sensor name is CPU Func 2 or CPU Core Func x, where x is 13 - 24, replace system processor
CPU 2.
Service action
Replace system processor CPU 1. If replacing system
processor CPU 1 does not resolve the problem, replace
system processor CPU 2. If replacing both system
processors does not resolve the problem, replace the
system backplane. Go to "8001-12C or 8005-12N
locations" on page 73 to identify the physical location
and removal and replacement procedure.
If replacing the system backplane and both system
processors does not resolve the problem, go to
"Contacting IBM service and support" on page 71. This
ends the procedure.
Replace system processor CPU 1. If replacing system
processor CPU 1 does not resolve the problem, replace
system processor CPU 2. If replacing both system
processors does not resolve the problem, replace the
system backplane. Go to "8001-22C or 8005-22N
locations" on page 87 to identify the physical location
and removal and replacement procedure.
If replacing the system backplane and both system
processors does not resolve the problem, go to
"Contacting IBM service and support" on page 71. This
ends the procedure.
