System
7063-CR1

EPUB_PRC_EIBUS_ERROR isolation procedure

A bus error occurred.
1. Can you boot the system to the Petitboot menu?
If Then
Yes: From the Petitboot menu, select Exit to shell. Then, continue with step 3 and list SELs by
using the Petitboot command line.
No: Continue with the next step.
2. Is another system available with the Linux operating system and ipmitool installed?
If Then
Yes: Continue with the next step and list SELs remotely over the LAN.
No: Go to "Collecting diagnostic data" on page 35. Then, go to "Contacting IBM service and
support" on page 35.
3. Use the ipmitool command to examine system event logs (SELs).
Service action
Replace the system backplane. If replacing the system
backplane does not resolve the problem, replace system
processor CPU 1. Go to "7063-CR1 locations" on page 37
to identify the physical location and removal and
replacement procedure.
If replacing the system backplane and the system
processor does not resolve the problem, go to
"Contacting IBM service and support" on page 35. This
ends the procedure.
Service action
Replace system processor CPU 1. If replacing the system
processor does not resolve the problem, replace the
system backplane. Go to "7063-CR1 locations" on page
37 to identify the physical location and removal and
replacement procedure.
If replacing the system backplane and the system
processor does not resolve the problem, go to
"Contacting IBM service and support" on page 35. This
ends the procedure.
