Title: Control channel to manager node down alarm Event ID: control_channel_to_manager_node_down Alarm Description
Purpose: Transport node's control plane connection to the Manager node is down.
Impact: In this scenario, no new configuration can be pushed down to the Transport node from the Control plane and features like vMotion will not be available.
Environment
VMware NSX
Resolution
Steps to Resolve For 4.1.0 and higher
Recommended Action:
Using ODS runbooks
Invoke CcpTNConnection runbook. Run following commands on any of the NSX Managers to invoke the runbook. /opt/vmware/nsx-netopa/bin/sha-appctl -c set_ods_level --level internal Retrieve the transport node name from System->Fabric->Hosts screen and replace the token '<TN_NAME>' in following command with it. /opt/vmware/nsx-netopa/bin/sha-appctl -c start_invocation --runbook CcpTNConnection --transport_node_name <TN_NAME> Above command will output an INVOCATION_UUID. Note this down and run the next command to get the status of the execution. /opt/vmware/nsx-netopa/bin/sha-appctl -c get_invocation_result --invocation <INVOCATION_UUID> -j
Once the runbook execution is complete, follow the instructions from the output. If no issue is detected, proceed to the next step.
Invoke nsx_proxy runbook on the Transport Node. Run following commands to invoke the runbook.Once the runbook execution is complete, follow the instructions from the output.
On ESX Node
/usr/lib/vmware/netopa/bin/sha-appctl -c set_ods_level --level internal /usr/lib/vmware/netopa/bin/sha-appctl -c start_invocation --runbook nsx_proxy Above command will output an INVOCATION_UUID. Note this down and run the next command to get the status of the execution. /usr/lib/vmware/netopa/bin/sha-appctl -c get_invocation_result --invocation <INVOCATION_UUID> -j
On Edge Node
/opt/vmware/nsx-netopa/bin/sha-appctl -c set_ods_level --level internal /opt/vmware/nsx-netopa/bin/sha-appctl -c start_invocation --runbook nsx_proxy Above command will output an INVOCATION_UUID. Note this down and run the next command to get the status of the execution. /opt/vmware/nsx-netopa/bin/sha-appctl -c get_invocation_result --invocation <INVOCATION_UUID> -j
Once the runbook execution is complete, follow the instructions from the output.
