Introduction to Cisco Unity Data and Message Storage

Information about subscriber accounts and other Cisco Unity data is stored in a SQL Server database on the Cisco Unity server. Additionally, a small subset of the Cisco Unity information is stored in the Domino directory. Cisco Unity keeps the information in the Domino directory and in the SQL Server database synchronized.

By storing its data in a SQL Server database, Cisco Unity derives many performance, reliability, and scalability benefits. Because very little information is stored in the Domino directory, and because that information is not likely to change often, directory replication caused by changes to Cisco Unity data is minimal after the initial creation of subscriber accounts.

Cisco Unity Functions When the Network Is Down

In addition to the SQL database that contains subscriber names and extensions, the Unity Messaging Repository (UMR) is also on the Cisco Unity server. When a Domino server or even the entire Domino network is down, Cisco Unity can answer calls, allow unidentified callers to look up subscriber extensions, and take voice messages. While the e-mail system or network is off line, new voice messages are stored in the UMR on the Cisco Unity server. During this time, subscribers checking their voice messages hear the UMR conversation, which explains that the Domino server is not available, but which gives them access to voice messages that have been left from the time that the Domino server went down. When the Domino server or network is back on line, the voice messages stored in the UMR are routed to the subscriber mailboxes.

Managing the Location of Log Files and Database Files

The way in which logical drives on the Cisco Unity server are partitioned and what content is located on the drives depends on the size of the Cisco Unity system and the RAID volume configuration used.

The partition and drive content recommendations from the Cisco Unity Installation Guide should continue to be followed when maintaining your system.

Moving Subscriber Mailboxes

From time to time you may need to move subscriber mailboxes to another server that is faster or has more disk space available, or you may want to move mailboxes when you add new servers to your network.

Caution If you are moving a group of subscriber mail files at once, confirm that you do not inadvertently select the Unity Messaging System mailbox. To move this special mail file, see the "Unity Messaging System Mailbox" section.

To Move Subscriber Mail Files Between Servers

Step 1 Follow the Lotus Domino procedures for moving mail files between servers.

Step 2 Restart the Cisco Unity server.

Note that Cisco Unity is not made aware of the new location of the mail file until either of the following occurs:

The subscriber person document is updated in the directory replica that Cisco Unity monitors (the partner mail server).

Cisco Unity synchronizes with the directory database.

Note also that if the destination server does not contain at least one other Cisco Unity subscriber mail file, notifications will not be sent when activity occurs on that subscriber mail file, including MWI notifications, until the Cisco Unity server is restarted.

Moving the Unity Messaging System Mailbox

The Unity Messaging System mailbox is a special mailbox with specific functions. You use the same procedures to move the Unity Messaging System mailbox that you use to move ordinary subscriber mailboxes—but with a few extra steps to prevent problems that can occur after this special mailbox is moved.

To avoid inadvertently moving the Unity Messaging System mailbox when you move a group of subscriber mailboxes, consider changing the display name so that this mailbox is clearly identified as requiring "special" treatment.

The following section describes the mailbox and how to move it correctly.

Unity Messaging System Mailbox

When an unidentified caller—an outside caller or a caller from inside the organization calling from a phone that is not associated with a subscriber account (such as a conference room)—leaves a message for a subscriber, Cisco Unity gives the message to the subscriber home server and stores it in the subscriber mailbox. Such messages are identified as coming from the Unity Messaging System mailbox, which is homed on the server that Cisco Unity gives the message to, and has the display name Unity Messaging System.

For more information on the Unity Messaging System mailbox and its associated account, refer to the "Default Accounts and Message Handling" chapter in the Cisco Unity System Administration Guide. The Cisco Unity System Administration Guide is available at

To Move the Unity Messaging System Mailbox

Step 1 Use the same procedures that you use for moving ordinary subscriber mailboxes in Lotus Domino.

Step 2 To prevent messages from unidentified callers from getting stuck in the Unity Messaging Repository (UMR) after the move, do the following sub-steps:

a. On the Windows Start menu, click Programs > Administrative Tools > Services.

b. From the Services window, stop and restart AvUMRSyncSvr service.

Step 3 To release any stuck NDRs from the Unity Messaging System mailbox, stop and restart the Cisco Unity software by using the system tray icon.
