Issue

  • ONTAP event log has csm.mismatchRemoteDevice ERROR events logged:

Thu Feb 17 11:52:05 +0100 [node-01: client_common_RPC: csm.mismatchRemoteDevice:error]: CSM connection between source LIF 1023 and destination address 169.254.13.13 might not be optimal for session 00001111deadbeef. The source is currently connected to - remote device and the destination is currently connected to myONTAPCluster remote device.

  • The IP-address referred within above error, i.e. 169.254.13.13, is a Cluster-LIF from another node in this cluster
  • The affected node which is reporting above error event, shows Csum Errors in CDP node statistics
  • After resetting the CDP node statistics, the Packets counter does increase by 1 Packet per Minute per Cluster-network-port along with Csum Errors raising at the same time as well
