  • AFF/FAS/ASA
  • AFF-A700
  • 9.12.1P11 CLUSTER-MODE

Issue

  • Multiple LIFs across four ports on Node A and Node B became unresponsive for the third time, but the physical links remained up.

  • Heavy load arriving at ports and ports are dropping them due to no buffer/bus overruns.

  • Port statistics indicate high bus_overruns and Rx_discards on QLogic X91143A CNAs in slots 1 and 10. 
  • Immediate connectivity will be restored through manual LIF Failover.
