Details

Predictive Self-Healing Article
PCIEX subsystem problem

Type

: Fault; fault.io.pciex.bus-linkerr-corr
fault.io.pciex.device-interr-corr

Severity

: Major

Description

: Too many recovered bus errors have been detected, which indicates a problem with the specified bus or with the specified transmitting device. This may degrade into an unrecoverable fault.

Automated Response

: One or more device instances may be disabled

Impact

: Loss of services provided by the device instances associated with this fault

Suggested Action for System Administrator

: If a plug-in card is involved check for badly-seated cards or bent pins.; Review documents in reference section for additional troubleshooting advice. Otherwise schedule a repair procedure to replace the affected device. Use fmadm faulty to identify the device or contact Sun for support.

Details

: Too many recovered bus errors have been detected, which indicates a problem with the specified bus or with the specified transmitting device. This may degrade into an unrecoverable fault.

Note:
There is a know issues where false hardware failures of this type can be seen.

See Alert <Document 1369835.1> Solaris 10 SPARC Kernel Patch 137137-09 May Cause Erroneous PCIEX-8000-KP Reports During PCIE Correctable Events

This issue is addressed in the following releases:
SPARC Platform: Solaris 10 with patch 147705-01 or later
X86 Platform: Solaris 10 with patch 147706-01 or later
Solaris 11 Express based upon builds snv_171 or later

Note: After installing the Solaris 10 patch, PCIEX-8000-KP faults should be cleared using the fmadm(1M) command.

Internal Note (1):
There is also an issue seen only on OPL platforms that may also cause this:

<BUG 15679335> PIC fabric errors seen during OPL M4/5000 production testing of Aura F20

Attached is the instructions to fix this issue on OPL Systems. PandoraAura-Reprogram.txt.zip

Internal Note (2):

Sun SPARC T5-x systems without system firmware 9.1.0.b (or later) may experience PCIe Root Complex Issues that result in the PCIEX-8000-KP diagnosis.

Please see document: (Doc ID 1582207.1) Upgrade Sun SPARC T5-x systems to system firmware 9.1.0.b (or later) to prevent C2C Link Training and PCIe Root Complex related faults
