faulty
Description : Too many recovered internal errors have been detected within the
specified PCIEX device. This may degrade into a non-recoverable
fault.
Refer to http://sun.com/msg/PCIEX-8000-J5 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
/pci@600/pci@1/pci@0/pci@4/pci@0/pci@3/SUNW,assigned-device@0
/SYS/PCI-EM4 PCIE SUNW,assigned-device-pciex10df,fc40 5.0GTx4
/pci@600/pci@1/pci@0/pci@4/pci@0/pci@3/SUNW,assigned-device@0,1
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
