Alert "Connectors unreachable" in VLCR UI

Products

• VMware Live Recovery

Issue/Introduction

The VMware Live Cyber Recovery (VLCR) UI displays a red status for a connector, reporting it as unreachable. This state prevents successful snapshots and management operations for the associated protection groups.

Symptoms:

• The VLCR UI displays the error: Connector in protected site #### is unreachable. Check network connectivity between the connector and the cloud file system.

• Executing drc network test --scope all from the connector CLI returns UNREACHABLE for the SCFS (Cloud File System) and ORCHESTRATOR entities, while the SUPPORT entity may remain REACHABLE.

• Example CLI output:

  • Connector_Appliance_VCDR01>> drc network test -- scope all

Environment

VMware Live Cyber Recovery 

Cause

This issue typically occurs when the communication between the VLCR connector and the Cloud components is interrupted. Common causes include:

• Network requirements not being met. Refer System and Network requirements 

• Recent upgrade activities done in VLCR.

• Time sync is off/time server is not configured on the Connector VM.

• DRCAgent service not running on the connector. 

Resolution

To restore connectivity, restart the connector appliance to re-initialize management services and force the DRC agent to perform a fresh handshake.

1. Ensure the time is synced on the Connector VMs.

2. Confirm that port 443 is opened in customer's AWS Security Groups along with other required ports for VLCR.

3. Log in to the vCenter Server and locate the unreachable connector appliance VM.

4. Restart the connector appliance. This forces the agent to re-read configuration and re-establish connection to the SCFS and Orchestrator.

5. Run drc network test to verify connectivity. refer Cyber Recovery Connector connectivity check tool.
