Problem Statement
Avaya System Manager (SMGR) reports a Minor alarm with maintenance object DRS_CLR_0004. The alarm description states: "Unable to get connection of node." This indicates that DRS is unable to connect to an element's DRS RMI interface.
Impact
DRS connectivity to the managed element may be unavailable while the alarm is active. This can occur during planned maintenance or network interruptions and may affect DRS-related communication with the element until connectivity is restored.
Alarm
DRS_CLR_0004
Troubleshooting Steps
- Confirm whether the managed element or Avaya System Manager is under planned maintenance. If maintenance is in progress, monitor the alarm until the maintenance window completes.
- Check basic network reachability between Avaya System Manager and the affected element using standard connectivity tests appropriate for the environment.
- Verify that the affected element is powered on, reachable, and not experiencing a service outage or reboot.
- Confirm that required management connectivity to the element is not being blocked by routing, firewall, or access-control changes.
- Review Avaya System Manager alarm history or dashboard status to determine whether the alarm is still active or has cleared.
- If the alarm remains active after maintenance and network connectivity are confirmed, investigate the DRS service or RMI interface availability on the affected element according to the applicable Avaya operational procedures.
- If the alarm clears and no further symptoms are present, document the event as transient and continue monitoring.
Resolution
In the observed case, the Minor DRS_CLR_0004 alarm cleared after investigation. No additional corrective action was documented. For future occurrences, validate maintenance status and network connectivity first, then confirm the alarm clears in Avaya System Manager.
