PCIe Correctable Errors Might Be Reported (CR 7051331)

In rare cases, PCIe Gen2 devices in the server module might report I/O errors that are identified and reported by predictive self-healing (PSH). For example:

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.
              Refer to http://sun.com/msg/PCIEX-8000-KP for more information.
 
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 faulty to identify the device or
              contact Sun for support.

These errors might be an indication of a faulty or incorrectly seated PCI EM. Or these errors might be erroneous.

Workaround: Ensure that the PCI EM is properly seated and functioning. If the errors continue, apply the Oracle Solaris 10 8/11 OS patch 147705-01 (or higher).
