I am actually not sure if the issue is specific to the R80.10_Take70 or if same could be applicable to the ealier HFAs.
The observed behavior is that Monitor shows incorrect status of the interfaces, as compared to the Gaia WebUI and the ClusterXL status of the node shown as "active":
In green frames are the interfaces that were removed from the cluster member, from both, Network properties of the Cluster and the WebUI. "Get Interfaces" was executed and the policy was pushed and installed. Node was rebooted.
The removed interfaces have eventually disappeared from the cluster's properties, but I was not able to determine the logic behind timing. Needless to say, the "Refresh" button did not do anything.
In the red frames are the "Cluster" interfaces marked "Down", despite being "Up" in WebUI, yet ClusterXL shows as Up as does Device status.
If someone has encountered this before, please let me know how this issue was addressed.
