Troubleshooting a Cisco Unity Connection 9.x Cluster Configuration

See the following sections:

Note The Cisco Unity Connection cluster feature is not supported for use with Cisco Unified Communications Manager Business Edition. Requirements for the Connection cluster feature are available in the “Requirements for a Cisco Unity Connection Cluster” section of System Requirements for Cisco Unity Connection Release 9.x, available at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/9x/requirements/9xcucsysreqs.html.

One Server Is Not Functioning and the Remaining Server Does Not Handle Calls in Cisco Unity Connection 9.x

When one Cisco Unity Connection server in a Connection cluster is not functioning (for example, when the subscriber server is undergoing maintenance) and the remaining server does not answer calls or send MWI requests, use the following task list to determine the cause and to resolve the problem.

Task List for Troubleshooting When One Server Is Not Functioning and the Remaining Server Does Not Handle Calls

1. Verify the status of the voice messaging ports in Cisco Unity Connection Serviceability. See the “Verifying the Status of the Voice Messaging Ports in Cisco Unity Connection Serviceability” section.

2. Verify the voice messaging port assignments for the phone system integration. See the “Verifying the Voice Messaging Ports Assignments for the Phone System Integration” section.

3. For SCCP integrations, confirm that the voice messaging ports are registered with the Cisco Unified CM server. See the “Confirming That the Voice Messaging Ports Are Registered (SCCP Integrations Only)” section.

4. Enable the SRM micro trace (all levels) in Cisco Unity Connection Serviceability. For detailed instructions on enabling the micro trace and viewing the trace logs, see the “Using Cisco Unity Connection Serviceability Traces to Troubleshoot Problems” section.

Verifying the Status of the Voice Messaging Ports in Cisco Unity Connection Serviceability

Do the following procedure.

To Verify the Status of the Voice Messaging Ports in Cisco Unity Connection Serviceability

Step 1 In Cisco Unity Connection Serviceability, on the Tools menu, select Cluster Management .

Step 2 On the Cluster Management page under Port Manager, verify the following for the server that should be handling calls:

    • In the Total Ports column, the number of ports that is listed is correct.
    • In the Change Port Status column, the Stop Taking Calls button appears. If the Take Calls button appears, select Take Calls .

 

Verifying the Voice Messaging Ports Assignments for the Phone System Integration

Do the following procedure.

To Verify the Voice Messaging Port Assignments for the Phone System Integration

Step 1 In Cisco Unity Connection Administration, expand Telephony Integrations , then select Phone System .

Step 2 In the Related Links list, select Check Telephony Integration and select Go .

The Task Execution Results displays one or more messages with troubleshooting steps.

Step 3 Follow the steps for correcting the problems.

Step 4 Repeat Step 2 through Step 3 until the Task Execution Results displays no problems.

 

Confirming That the Voice Messaging Ports Are Registered (SCCP Integrations Only)

For Cisco Unified CM SCCP integrations, do the following procedure.

To Confirm That the Voice Messaging Ports Are Registered (SCCP Integrations Only)

Step 1 In Cisco Unified CM Administration, on the Voice Mail menu, select Voice Mail Port .

Step 2 On the Find and List Voice Mail Ports page, select Find .

Step 3 In the Status column, confirm that all ports show the status of “ Registered with <server name> .”

 

Both Servers Have Primary Server Status in Cisco Unity Connection 9.x

Use the troubleshooting information in this section if both servers in the Cisco Unity Connection cluster have Primary server status (a “split brain” condition). See the following possible causes:

  • The network is not functioning or is preventing the publisher and subscriber servers from communicating with each other.

The solution is to restore the network connection so that the publisher and subscriber servers can communicate.

  • The host name for the subscriber server was changed and is not entered correctly on the System Settings > Cluster page of the publisher server.

The solution is to enter the correct host name of the subscriber server on the System Settings > Cluster page of the publisher server.

After the Subscriber Server is Reinstalled, the Cluster Status is Not Updated on both the Publisher and Subscriber Servers

Use the troubleshooting information in this section if the cluster status is not updated on both the servers in Connection 8.x cluster. See the following possible issues:

  • The subscriber server fails to be added to the cluster in Unity Connection 8.x even after it has been successfully reinstalled. The cluster status on subscriber server that is displayed by the CLI command show cuc cluster status, returns an error as:

Incorrect password or user com.informix.asf.IfxASFRemoteException: cucli@servername is not known on the database server

  • The cluster status on publisher server that is displayed by the CLI command show cuc cluster status, returns an error as:

<The publisher as single server>

Database replication is not active.

 

Follow the given steps to resolve this issue:

  • Contact TAC for assistance. The TAC engineer must take the root access of the publisher server and tear down the replication between publisher and subscriber server.
  • Rebuild the subscriber server after this to resolve the issue.

Cisco Unity Connection 9.x Cluster Is Not Functioning Correctly

When a Cisco Unity Connection cluster is not functioning correctly (for example, server status does not change when expected), use the following task list to determine the cause and to resolve the problem. Do the tasks in the order presented until the problem is resolved.

Task List for Troubleshooting a Cisco Unity Connection Cluster That Is Not Functioning Correctly

1. Confirm that the applicable services are running on the server with primary server status. See the “Confirming That the Applicable Services Are Running on the Server with Primary Server Status” section.

2. Confirm that the applicable services are running on both servers. See the “Confirming That the Applicable Services Are Running on Both Servers” section.

3. Use traces to troubleshoot the Connection cluster. For detailed instructions on enabling the applicable traces and viewing the trace logs, see the “Traces in Cisco Unity Connection Serviceability in Cisco Unity Connection 9.x” section.

Confirming That the Applicable Services Are Running on the Server with Primary Server Status

Do the following procedure.

To Confirm That the Applicable Services Are Running on the Server with Primary Server Status

Step 1 In Cisco Unity Connection Serviceability, on the Tools menu, select Service Management .

Step 2 On the Control Center - Feature Services page, under Critical Services, confirm that the following services have the Started service status:

    • Connection Message Transfer Agent
    • Connection Notifier

Step 3 If the services have the Stopped service status, select Start .

 

Confirming That the Applicable Services Are Running on Both Servers

Do the following procedure.

To Confirm That the Applicable Services Are Running on Both Servers

Step 1 In Cisco Unity Connection Serviceability, on the Tools menu, select Service Management .

Step 2 On the Control Center - Feature Services page, under Status Only Services, confirm that the Connection Server Role Manager service has the Started service status.

The services in the Status Only Services section cannot be started in Cisco Unity Connection Serviceability. You must use the command line interface (CLI) to start or stop these services. For information on the CLI, see the Command Line Interface Reference Guide for Cisco Unified Communications Solutions Release 9.0(1) at http://www.cisco.com/en/US/products/ps6509/prod_maintenance_guides_list.html .
