Symptoms

The OBP shows all NIC cards (T5-2 in this case), but prtdiag doesn't list the ports from one of the NIC cards:

{0} ok [oracle.com] show-nets
a) /pci@380/pci@1/pci@0/pci@5/network@0,1   PCIe 2
b) /pci@380/pci@1/pci@0/pci@5/network@0
c) /pci@3c0/pci@1/pci@0/pci@1/network@0,1    NET 3
d) /pci@3c0/pci@1/pci@0/pci@1/network@0      NET 2
e) /pci@300/pci@1/pci@0/pci@4/network@0,1   PCIe 1
f) /pci@300/pci@1/pci@0/pci@4/network@0
g) /pci@300/pci@1/pci@0/pci@1/network@0,1   NET 1
h) /pci@300/pci@1/pci@0/pci@1/network@0      NET 0
q) NO SELECTION

prtdiag does not contain PCIe 2.  NIC PCI card replacement does not resolve the problem.

 

/etc/path_to_inst contains an entry for the missing NIC.

"/pci@380" 3 "px"
"/pci@380/pci@1" 16 "pcieb"
"/pci@380/pci@1/pci@0" 17 "pcieb"
"/pci@380/pci@1/pci@0/pci@5" 19 "pcieb"
"/pci@380/pci@1/pci@0/pci@5/network@0" 6 "ixgbe"
"/pci@380/pci@1/pci@0/pci@5/network@0,1" 7 "ixgbe"


Another possible symptom is many btlp & ce ereports related to NIC PCI card paths over time.
