You can remove an Expressway node from a resource in Cisco Spark Control Hub, but this works best for nodes that no longer exist on the premises (due to a hardware failure, for example).
Even if you remove the node from the clustering setup on the Expressway, the node still contains its hybrid services setup, continues to connect, and appears as part of the same resource in Cisco Spark Control Hub. Use this procedure to fully remove the node.
|1|| Put the node in to maintenance mode:|
|2|| Use Expressway to remove the node from the cluster:|
These steps are a guideline. From the related links, you may also check the Cisco Expressway Cluster Creation and Maintenance Deployment Guide for your Expressway version.
|3|| From the Expressway node being removed, go to Applications > Hybrid Services > Connector Management, and then click Deregister to completely stop the connection with the cloud. |
After the node is deregistered, the cloud marks node as offline. This update might take a few minutes. For further cleanup, you can then remove from the cloud using the Remove Node option in Cisco Spark Control Hub.
For nodes that still exist, they return to the Cisco Spark Control Hub list when the next heartbeat connection is established.
