Disabling the connection

Disable the connection between Hub and Spoke.

About this task

In Hub and Spoke, there is a connection CR in each cluster that represents the connection to the another(remote) cluster. Delete connection CR in the Spoke or Hub. If the network is down, then use either method 1 or method 2 to manually delete the connection CR in another cluster also.

Method 1: Using command line or command prompt

Procedure

  1. In the Spoke, use the following command to get all the connection CR: 
    oc get connection -n <fusion-namespace> -o=custom-columns='NAME:.metadata.name,ClusterName:.metadata.annotations.connection\.isf\.ibm\.com/cluster-name'
    Example command: 
    oc get connection -n ibm-spectrum-fusion-ns -o=custom-columns='NAME:.metadata.name,ClusterName:.metadata.annotations.connection\.isf\.ibm\.com/cluster-name'
    Example output:
    NAME                    ClusterName
connection-44ae8529aa   cp4d-vpc-98b7318c91b01bd72490e80cc2328915-0000.us-east.containers.appdomain.cloud
  2. Check the ClusterName in connection CR, and delete the connection CR which has the same ClusterName with Hub: 
    oc delete connection <connection-name>  -n <fusion-namespace>
    Example command:
    oc delete connection connection-44ae8529aa -n ibm-spectrum-fusion-ns

Method 2: By using OpenShift Container Platform console

Procedure

  1. Log in to OpenShift® Container Platform console.
  2. Go to Administration > CustomResourceDefinitions > connections.application.isf.ibm.com > Instances.
  3. Get the connection instance whose cluster name in the annotation is the same as the hub cluster name.
  4. Delete this connection instance.
