csm.mismatchRemoteDevice message appears in event log:
WARNING csm.mismatchRemoteDevice: CSM connection between source LIF 1023 and destination address <cluster_ip> might not be optimal for session 0104d263bc58cd05. The source is currently connected to <device_name> remote device and the destination is currently connected to <device_name> remote device.
device_name entries can be cluster switch names, node names or dashes (-). The contents of the message help determine the cause and required troubleshooting.
This occurs when Cluster Session Manager (CSM) establishes a connection between nodes over cluster network interface; however, the nodes' remote device IDs do not match.
