Description : Too many recovered internal errors have been detected within the
specified PCIEX device. This may degrade into a non-recoverable
Refer to 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 : Schedule a repair procedure to replace the affected device. Use
fmadm faulty to identify the device or contact Sun for support.


All 371-4666-02 Emulex HBAs should operate at PCIe Gen1 (2.5GT/s), if they are not then there is a risk they will suffer from excessive PCIe correctable errors. In order to confirm the cards configured operating speed first check prtdiag;

/SYS/PCI-EM4 PCIE SUNW,assigned-device-pciex10df,fc40 5.0GTx4
/SYS/PCI-EM4 PCIE SUNW,assigned-device-pciex10df,fc40 5.0GTx4


In this example the impacted device is operating at the incorrect PCIe Gen2 speed (5.0GT/s) and should be replaced.

Alternatively run operations POST mode, the PCIe switch configuration including link speed and width will be reported towards the end of POST.


On the SP;

set /HOST/diag mode=ops0

set /HOST/diag level=max

set /HOST/diag verbosity=max
