  • All ports in IFGroup do not stay online, active ports are bouncing between none and partial
  • In EMS log we see the error:
[node: nblade1: netif.linkDown:info]: Ethernet a0a: Link down, check cable.
  • System manger reports One network interface not at home port when the physical port is down
  • Re-adding the physical port to the IFGRP fails:
::> network port ifgrp add-port -node <node> -ifgrp <ifgrp> -port <port>
