Use this information to isolate problems that might occur with your system.

EPUB_PRC_FIND_DECONFIGURE_PART isolation procedure

A part vital to the system has been deconfigured.
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 110. This ends the procedure.
3. Is your system an 8335-GCA, 8335-GTA, or 8335-GTB?
If Then
Yes: Continue with the next step.
No: Continue with step 5 on page 97.
4. 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:
