Cisco unity connection question

Hi Uday,

The Cluster in Unity Connection acts differently than a CUCM cluster, so the answers to your question are;

Yes & Yes

How a Cluster Works in Cisco Unity Connection

Revised May 2009

The Cisco Unity Connection cluster feature provides high availability  voice messaging through two Connection servers that are configured in a  cluster. Under normal conditions, the Connection servers are both active  so that:

The cluster can be assigned a DNS name that is shared by the Connection servers.

Clients  such as email applications and the web tools available through the  Cisco Personal Communications Assistant (PCA) can connect to either  Connection server.

Phone systems can send calls to either Connection server.

Incoming  phone traffic load is balanced between the Connection servers by the  phone system, PIMG/TIMG units, or other gateways that are required for  the phone system integration.

Each server in the cluster is responsible for handling a share of the  incoming calls for the cluster (answering phone calls and taking  messages). The server with Primary status is responsible for the  following functions:

Homing and publishing the database and message store, which are both replicated to the other server.

Sending message notifications and MWI requests (the Connection Notifier service is activated).

Sending SMTP notifications and VPIM messages (the Connection Message Transfer Agent service is activated).

When one of the servers stops functioning (for example, when it is shut  down for maintenance), the remaining server assumes responsibility for  handling all incoming calls for the cluster. The remaining server also  assumes responsibility for the database and message store, which are  both replicated to the other server when the connection and its  functionality are restored.

When the server that stopped functioning is able to resume its normal  functions and is activated, it resumes responsibility for handling its  share of incoming calls for the cluster.

To monitor the status of the servers, the Connection Server Role Manager  service runs in Cisco Unity Connection Serviceability on both servers.  This service performs the following functions:

Starts the applicable services on each server, depending on server status.

Determines  whether critical processes (such as voice message processing, database  replication, and message store replication) are functioning normally.

Initiates  changes to server status when the server with Primary status is not  functioning or when critical services are not running.

Note the following limitations when the publisher server is not functioning:

If  the Connection cluster is integrated with an LDAP directory, directory  synchronization does not occur, although authentication continues to  work when only the subscriber server is functioning. When the publisher  server is functioning again, directory synchronization resumes.

If  a Digital Network includes the Connection cluster, directory updates do  not occur, although messages continue to be sent to and from the  cluster when only the subscriber server is functioning. When the  publisher server is functioning again, directory updates resume.

About the Publisher Server

The first Cisco Unity Connection server that is configured in the  cluster is the publisher server. The Cluster Management page in  Cisco Unity Connection Serviceability identifies the publisher server.

The publisher server assumes responsibility for publishing the database  and message store when the cluster is functioning normally.

When the publisher server does not have Primary status (for example,  when the administrator manually changes the status of the other server  to Primary, which automatically changes the status of the publisher  server to Secondary), the other server assumes responsibility for  publishing the database and message store.

The publisher server cannot be removed from the cluster.
