DIMM Fault SPX86A-800A-95 - Memtest Single Symbol Test Failed - ILOM 5.1.0.21
Bug ID: 34325538, 34445460
Issue: The following DIMM Fault message is seen: SPX86A-800A-95 - Memtest Single Symbol Test Failed (Doc ID 2317012.1)
SPX86A-800A-95 indicates that the ILOM fault manager has received an error report
indicating a memory DIMM produced correctable errors (CE) during both passes of the memory
test.
If the server encounters multiple runtime memory fault related events, increased runtime error messages may be related to DIMM memory testing conditions. Oracle ILOM Adaptive Double DRAM Device Correction (ADDDC) and Post Package Repair (PPR) features are enabled in the server firmware. ADDDC Sparing is a RAS feature to test memory reliability. The Advanced Memory Test (AMT) in the Memory Reference Code (MRC) can fail a DIMM with a single symbol error and then PPR would try to repair the defect.
When enabled, PPR may be able to repair affected DRAM areas on a DIMM. PPR runs when ADDDC was previously activated before reboot or MRC initialization failed memory tests. Upon encountering any memory related fault event during MRC initialization or experiencing certain memory correctable events during runtime that triggers ADDDC on first occurrence, then PPR would be activated after the next system initialization/reboot and attempt to repair the DIMM.
Note:
Certain DIMM manufacturers may exhibit different memory failure patterns, and may not support soft PPR configuration (which enables temporarily attempting a repair action).
Affected Hardware: Oracle Server X9-2, Oracle Server X9-2L, Oracle Server X8-8, Oracle Server X8-2, Oracle Server X8-2L, Oracle Server X7-8, Oracle Server X7-2, Oracle Server X7-2L
Note:
Not all server systems enable ADDDC.
Affected Software:
The following x86 server software Oracle ILOM releases or later, support PPR (Post-Package Repair).
- Oracle Server X9-2 SW1.1.0 ILOM 5.0.2.21 (Does not enable ADDDC.)
- Oracle Server X9-2L SW1.1.0 ILOM 5.0.2.21 (Does not enable ADDDC.)
- Oracle Server X8-8 SW3.2.2.1 ILOM 5.0.2.22 (Does not enable ADDDC.)
- Oracle Server X8-2 SW3.2.2 ILOM 5.0.2.24
- Oracle Server X8-2L SW3.2.2 ILOM 5.0.2.24
- Oracle Server X7-8 SW3.2.2.1 ILOM 5.0.2.22 (Does not enable ADDDC.)
- Oracle Server X7-2 SW3.2.2 ILOM 5.0.2.24
- Oracle Server X7-2L SW3.2.2 ILOM 5.0.2.24
Workaround: Some DIMM faults are recoverable errors if PPR is enabled on the server. If multiple DIMM memory errors are detected on the server:
- Log in to the Oracle ILOM command-line interface (CLI) using an account with admin (a) role privileges.
- From the Oracle ILOM CLI, launch the Oracle ILOM Fault Management Shell.
-> start /SP/faultmgmt/shell Are you sure you want to start /SP/faultmgmt/shell (y/n)? y
- Display information about server components using Oracle ILOM FMA CLI
command.
faultmgmtsp>
fmadm faulty
- Manually clear server faults using Oracle ILOM FMA CLI
command.
faultmgmtsp>
fmadm repair <FRU>
- Exit the Oracle ILOM Fault Management Shell and return to the the Oracle
ILOM CLI command prompt.
faultmgmtsp>
exit
- Upgrade the server to the latest ILOM/UEFI firmware release that supports PPR. The system resets during the firmware upgrade and runs memory tests again.
- If memory related events faults continue to be logged, replace the faulted DIMMs in the server. Log an Oracle Support case through the support portal for further assistance.
For updated information about Oracle ILOM, refer to Oracle Integrated Lights Out Manager (ILOM) documentation at Servers Documentation - Systems Management.
Oracle Service personnel can find more information about the diagnosis and triage of DIMM Fault failures on x86 servers at My Oracle Support. Refer to the Knowledge Article Doc ID 2698328.1. If there are multiple, simultaneous DIMM Fault message problems on a server, Oracle Service personnel can refer to Knowledge Articles Doc IDs 1603015.1 (KA single symbol error) and 2317012.1 (KA multiple symbol errors).
Note:
Adaptive Double DRAM Device Correction (ADDDC) is also referred to as Adaptive Device Correction (ADC) in some Oracle documents.Parent topic: Oracle ILOM Issues
Resolving Warning Messages for Custom CA and Self-Signed SSL Certificates
Important Operating Note
The following information applies to users of the Oracle ILOM Remote System Console and the Oracle ILOM Remote System Console Plus.
A warning message occurs when the Java client is not properly configured to validate the Secure Sockets Layer (SSL) certificate that is currently being using by Oracle ILOM. This validation behavior applies to Oracle ILOM firmware version 3.2.8 or later for systems using the default self-signed SSL certificate, and to Oracle ILOM firmware version 3.2.10 and later for systems using a Custom Certification Authority (CA) SSL certificate.
To resolve the SSL warning message, refer to the following applicable sections in the Oracle ILOM Administrator’s Guide for Configuration and Maintenance Firmware Release 5.0.x, which is available at https://www.oracle.com/goto/ilom/docs :
-
“Warning Messages for Self-Signed SSL Certificate”
-
“Resolving Warning Messages for Custom Certification Authority (CA) SSL Certificate”

Changes to TLSv1.1 Configuration Property
Important Operating Note
Present Behavior: The Oracle ILOM TLSv1.1 configuration property is Enabled by default.
Future Behavior: The following changes will occur to the TLSv1.1 configuration property sometime after the Oracle ILOM 4.0.3 firmware release:
-
First Change: The TLSv1.1 configuration property will default to Disabled in the next minor release of Oracle ILOM.
-
Second Change: The TLSv1.1 configuration property will no longer be supported and will be removed from all Oracle ILOM user interfaces in the next major release of Oracle ILOM.
For future updates regarding TLSv1.1 support in Oracle ILOM, refer to latest release information in the Oracle ILOM Feature Updates and Release Notes for Firmware 5.0.x at https://docs.oracle.com/cd/E81115_01/index.html .

Deprecation Notice for Oracle ILOM IPMI 2.0 Management Service
Important Operating Note
Present Behavior: IPMI 2.0 Management Sessions - Enabled (default setting).
Future Behavior: The following IPMI Management Service changes will occur in a future Oracle ILOM firmware release after firmware version 4.0.2.
-
First IPMI Service Support Change – The default configuration property for IPMI 2.0 Sessions will change from Enabled to Disabled. Clients relying on Oracle ILOM IPMI 2.0 session support by default will no longer be able to communicate with Oracle ILOM. To enable IPMI communication with Oracle ILOM, perform one of the following:
-
Use the Oracle IPMI TLS service and interface. For more information, refer to “IPMI TLS Service and Interface” in the Oracle ILOM Protocol Management Reference SNMP and IPMI Firmware Release 5.0.x.
or
-
Manually enable the configuration property for IPMI 2.0 Session. For details, refer to “IPMI Service Configuration Properties” in the Oracle ILOM Administrator’s Guide for Configuration and Maintenance Firmware Release 5.0.x.
-
-
Second IPMI Service Support Change – Removal of IPMI 2.0 client support. IPMI 2.0 clients no longer will be able to communicate with Oracle ILOM. Clients relying on IPMI communication will need to use the IPMI TLS service and interface. For more information, refer to “IPMI TLS Service and Interface” in the Oracle ILOM Protocol Management Reference SNMP and IPMI Firmware Release 5.0.x.
For future updates about IPMI Management Service support in Oracle ILOM, refer to the latest firmware release information published in the Oracle ILOM Feature Updates and Release Notes Firmware Release 5.0.x. You can access the Oracle ILOM documents at https://www.oracle.com/goto/ilom/docs .
