Description

An issue with the Fault Management Architecture (FMA) in Solaris 10 SPARC kernel patch 137137-09 and certain Solaris 11 Express builds, may cause erroneous PCIEX-8000-KP reports during PCIE correctable events. These erroneous reports may result in unnecessary hardware replacements.

Likelihood of Occurrence

This issue can occur in the following releases:

SPARC Platform

Solaris 10 with patch 137137-09 and without patch 147705-01
Solaris 11 Express based upon builds snv_87 through snv_170

Note 1: All SPARC platforms with PCI-E I/O Expansion Slots are impacted by this issue.

Note 2: Solaris 8, Solaris 9, and Solaris on the x86 platform are not impacted by this issue.

Note 3: Solaris 11 Express distributions may include additional bug fixes above and beyond the build from which it was derived. The base build can be derived as follows:

   $ uname -v
   snv_151

If the output is of the format 151.x.x.x, then the build installed is snv_151.

Possible Symptoms

When patch 137137-09 is installed, or a system is upgraded to a release that includes this patch or to an affected Solaris 11 Express build, FMA may report correctable errors not previously observed on the system. Eventually suspect devices may be reported faulty if Soft Error Rate Discrimination (SERD) thresholds are exceeded.

If the described issue occurs, the following message will be seen on the system console:

    SUNW-MSG-ID: PCIEX-8000-KP, TYPE: Fault, VER: 1, SEVERITY: Major
    EVENT-TIME: Tue Mar  29 21:03 PDT 2011
    PLATFORM: SUNW,SPARC-Enterprise , CSN: -, HOSTNAME: -
    SOURCE: eft, REV: 1.16
    EVENT-ID: af46a1fb-a712-617b-cab3-fc57b79a1dd9
    DESC: 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.
    
    Refer to http://sun.com/msg/PCIEX-8000-KP for more information.
    
    AUTO-RESPONSE: One or more device instances may be disabled

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

    REQ-ACTION: If a plug-in card is involved check for badly-seated cards or bent pins. Otherwise schedule a repair procedure 
    to replace the affected device.

Use fmadm(1M) faulty to identify the device or contact Oracle for support.

    Response: One or more device instances may be disabled.
    
    Impact: Loss of services provided by the device instances associated with this fault

    Action: If a plug-in card is involved check for badly-seated cards or 
    bent pins. Otherwise schedule a repair procedure to replace the 
    affected device.  Use fmadm(1M) faulty to identify the device or contact Oracle for support.

Then execute the fmstat(1M) command to determine if a SERD threshold has been exceeded.

Note: The output seen when encountering this issue will vary depending upon the patch level and affected SERD threshold as follows:

For patch 142909-17 or patch 147440-01:

    # fmstat -s -m eft
    NAME >N     T CNT                DELTA STAT
    serd.io.device.nonfatal_bdllp@... >6    2h   3    ...
    serd.io.pciex.corrlink-bus_bdllp@... >6    2h   3   ...

or
    serd.io.device.nonfatal_btlp@... >6    2h   3     ...
    serd.io.pciex.corrlink-bus_btlp@ >6    2h   3    ...

or

    serd.io.device.nonfatal_re@... >6    2h   3      ...
    serd.io.pciex.corrlink-bus_re@... >6    2h   3     ...

For patch 141444-09:


    # fmstat -s -m eft
    NAME >N     T CNT                DELTA STAT
    serd.io.device.nonfatal_corr@.. >6    2h   3    ...
    serd.io.pciex.corrlink-bus@... >6    2h   3       ...

For patch 137137-09 or patch 139555-08:

    # fmstat -s -m eft
    NAME >N     T CNT                DELTA STAT
    serd.io.pciex.corrlink@.. >6    2h   3          ...

Workaround or Resolution

There is no workaround for this issue.

This issue is resolved in the following releases:

SPARC Platform

Solaris 10 with patch 147705-01 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.

    # fmadm repaired <EVENT-ID >

where the event-id is obtained from the output from the "fmadm faulty" command as shown in the symptoms section above.

Internal Notes:

This regression was caused by the putback for CR 6510830.
This was taken into patch 137137-02, but the only revision of this patch available to customers is 137137-09.

In Solaris 11 Express 2010.11 this issue is resolved in SRU12. The SRU installed on a customer system may be determined by running the following command:

    # pkg info entire | grep Summary
    
    Summary: entire incorporation including Support Repository 
    Update (Oracle Solaris 11 Express 2010.11 SRU 11). (....)
