Server Configuration Settings

Use the Server Configuration window to specify the address of the server where Cisco Unified Communications Manager is installed. Table 2-1 describes the server configuration settings. For related procedures, see the "Related Topics" section.

Before You Begin

Before you configure a server, review the following information:

Make sure that you only add each server once in the Server Configuration window. If you add a server by using the hostname and add the same server again by using the IP address, Cisco Unified Communications Manager cannot accurately determine component versions for the server after a Cisco Unified Communications Manager upgrade. If you have two entries in Cisco Unified Communications Manager Administration for the same server, delete one of the entries before you upgrade (see the "Deleting a Server" section).

When you perform a fresh installation of Cisco Unified Communications Manager, you must define any subsequent servers (nodes) in the Cisco Unified Communications Manager Administration Server Configuration window before you can install Cisco Unified Communications Manager on each subsequent server. To define a subsequent node, click Add New and perform the procedure in the "Configuring a Server" section. After you add the subsequent server, you can then install the Cisco Unified Communications Manager software on that server.

If you use IPv4 in your network, you must update the DNS server with the appropriate Cisco Unified Communications Manager name and address information before you use that information to configure the Cisco Unified Communications Manager server.


Caution If your network supports IPv6 or IPv4 and IPv6 in dual-stack mode, you can provision your DNS server for IPv6 prior to upgrading from Cisco Unified Communications Manager Release 7.0(x) to Release 8.0(2). However, do not configure the DNS records for Cisco Unified Communications Manager for IPv6 until after you upgrade to Release 8.0(2). Configuring the DNS records for Cisco Unified Communications Manager for IPv6 prior to upgrading to Release 8.0(2) causes the upgrade to fail and causes your system to become nonfunctional after you reboot.

For DNS, make sure that you map the IP addresses of all servers, including dummy nodes, to the host names on the DNS server. If you do not perform this task, Cisco Unified Communications Manager generates alarms that inform you that the License Manager service is down.

Cisco Unified Communications Manager Administration does not prevent you from updating the IP Address field under any circumstances.

When you attempt to change the IP address in the Server Configuration window, the following message displays after you save the configuration: "Changing the host name/IP Address of the server may cause problems with Cisco Unified Communications Manager. Are you sure that you want to continue?" Before you click OK, make sure that you understand the implications of updating the Host Name/IP Address field; for example, incorrectly updating this setting may cause Cisco Unified Communications Manager to become inoperable; that is, the database may not work, you may not be able to access Cisco Unified Communications Manager Administration, and so on. In addition, updating this field without performing other related tasks may cause problems for Cisco Unified Communications Manager.

For additional information on changing the IP address or host name, refer to the document, Changing the IP Address and Host Name for Cisco Unified Communications Manager Release 8.0(2).

Table 2-1 Server Configuration Settings 

Field
Description
Server Information

Host Name/IP Address

If your network uses DNS that can map to IPv4 addresses, you can enter the host name of the Cisco Unified Communications Manager server. Otherwise, you must enter the full IPv4 address of the server.

Tip If your network supports IPv6 (or IPv4 and IPv6), configure the IPv6 Name field in addition to the Hostname/IP Address field.

Note You must update the DNS server with the appropriate Cisco Unified Communications Manager name and address information before you enter that information in this field.

IPv6 Name

This field supports IPv6. If your network uses DNS that can map to IPv6 addresses, you can enter the host name of the Cisco Unified Communications Manager server. Otherwise, enter the non-link-local IP address of the Cisco Unified Communications Manager server; for information on how to obtain the non-link local IP address, refer to "Running IPv6 CLI Commands or Configuring IPv6 in the Ethernet IPv6 Window" in the Cisco Unified Communications Manager Features and Services Guide.

This field, which gets included in the TFTP configuration file, gets used by phones that run SCCP to retrieve the IPv6 address of the Cisco Unified Communications Manager server, so phone registration occurs.

Tip Remember to update the DNS server with the appropriate Cisco Unified Communications Manager name and address information.

Caution If your network supports IPv6 or IPv4 and IPv6 in dual-stack mode, you can provision your DNS server for IPv6 prior to upgrading from Cisco Unified Communications Manager Release 7.0(x) to Release 8.0(2). However, do not configure the DNS records for Cisco Unified Communications Manager for IPv6 until after you upgrade to Release 8.0(2). Configuring the DNS records for Cisco Unified Communications Manager for IPv6 prior to upgrading to Release 8.0(2) causes the upgrade to fail and causes your system to become nonfunctional after you reboot.
Tip In addition to configuring the IPv6 Name field, you must configure the IP Address/Hostname field, so Cisco Unified Communications Manager can support features/devices that use IPv4 (or IPv4 and IPv6).

MAC Address

Consider this entry as optional.

Enter the media access control (MAC) address of the network interface card (NIC) in the Cisco Unified Communications Manager server. The MAC address specifies the permanent hardware address of the NIC.

Tip If you plan to move the server periodically to different locations on the network, you must enter the MAC address, so other devices on the network can always identify the server. If you do not plan to relocate the server, consider entry of the MAC address as optional.

Description

Consider this entry as optional.

Enter a description of the server. The description can include up to 50 characters in any language, but it cannot include double-quotes ("), percentage sign (%), ampersand (&), back-slash (\), or angle brackets (<>).


Finding a Server

Because you might have several servers in your network, Cisco Unified Communications Manager lets you locate specific servers on the basis of specific criteria. Use the following procedure to locate servers.


Note During your work in a browser session, the cookies on the client machine store your find/list search preferences. If you navigate to other menu items and return to this menu item, or if you close the browser and then reopen a new browser window, your Cisco Unified Communications Manager search preferences get retained until you modify your search.


Procedure


Step 1 Choose System > Server.

The Find and List Servers window displays. Records from an active (prior) query may also display in the window.

Step 2 To find all records in the database, ensure the dialog box is empty; go to Step 3.

To filter or search records

From the first drop-down list box, select a search parameter.

From the second drop-down list box, select a search pattern.

Specify the appropriate search text, if applicable.


Note To add additional search criteria, click the + button. When you add criteria, the system searches for a record that matches all criteria that you specify. To remove criteria, click the - button to remove the last added criterion or click the Clear Filter button to remove all added search criteria.


Step 3 Click Find.

All matching records display. You can change the number of items that display on each page by choosing a different value from the Rows per Page drop-down list box.


Note You can delete multiple records from the database by checking the check boxes next to the appropriate record and clicking Delete Selected. You can delete all configurable records for this selection by clicking Select All and then clicking Delete Selected.


Step 4 From the list of records that display, click the link for the record that you want to view.


Note To reverse the sort order, click the up or down arrow, if available, in the list header.


The window displays the item that you choose.

Configuring a Server

This section describes how to add or update a server address to the Cisco Unified Communications Manager database.

Before You Begin

Before you configure a server, review the following information:

Make sure that you only add each server once on the Server Configuration window. If you add a server by using the host name and add the same server by using the IP address, Cisco Unified Communications Manager cannot accurately determine component versions for the server after a Cisco Unified Communications Manager upgrade. If you have two entries in Cisco Unified Communications Manager Administration for the same server, delete one of the entries before you upgrade (see the "Deleting a Server" section).

When you perform a fresh installation of Cisco Unified Communications Manager, you must define any subsequent servers (nodes) in the Cisco Unified Communications Manager Administration Server Configuration window before you can install Cisco Unified Communications Manager on each subsequent server. To define a subsequent node, click Add New and perform the procedure in the "Configuring a Server" section. After you add the subsequent server, you can then install the Cisco Unified Communications Manager software on that server.

If you use IPv4 in your network, you must update the DNS server with the appropriate Cisco Unified Communications Manager name and address information before you use that information to configure the Cisco Unified Communications Manager server.


Caution If your network supports IPv6 or IPv4 and IPv6 in dual-stack mode, you can provision your DNS server for IPv6 prior to upgrading from Cisco Unified Communications Manager Release 7.0(x) to Release 8.0(2). However, do not configure the DNS records for Cisco Unified Communications Manager for IPv6 until after you upgrade to Release 8.0(2). Configuring the DNS records for Cisco Unified Communications Manager for IPv6 prior to upgrading to Release 8.0(2) causes the upgrade to fail and causes your system to become nonfunctional after you reboot.

For DNS, make sure that you map the IP addresses of all servers, including dummy nodes, to the host names on the DNS server. If you do not perform this task, Cisco Unified Communications Manager generates alarms that inform you that the License Manager service is down.

Cisco Unified Communications Manager Administration does not prevent you from updating the IP Address field under any circumstances.

When you attempt to change the IP address in the Server Configuration window, the following message displays after you save the configuration: "Changing the host name/IP Address of the server may cause problems with Cisco Unified Communications Manager. Are you sure that you want to continue?" Before you click OK, make sure that you understand the implications of updating this field; for example, incorrectly updating this setting may cause Cisco Unified Communications Manager to become inoperable; that is, the database may not work, you may not be able to access Cisco Unified Communications Manager Administration, and so on. In addition, updating this field without performing other related tasks may cause problems for Cisco Unified Communications Manager.

Changes to the server configuration do not take effect until you restart Cisco Unified Communications Manager. For information about restarting the Cisco CallManager service, refer to the Cisco Unified Serviceability Administration Guide.

For additional information on changing the IP address or host name, refer to the document, Changing the IP Address and Host Name for Cisco Unified Communications Manager Release 8.0(2).

Procedure


Step 1 Perform one of the following tasks:

To add a server, choose System > Server and click Add New.

To update a server, find the server by using the procedure in the "Finding a Server" section.

The Server Configuration window displays.

Step 2 Enter the appropriate settings as described in Table 2-1.

Step 3 To save the data and to add the server to the database, click the Save icon that displays in the tool bar in the upper, left corner of the window (or click the Save button that displays at the bottom of the window).

Changes to the server configuration do not take effect until you restart Cisco Unified Communications Manager. For information about restarting the Cisco CallManager service, refer to the Cisco Unified Serviceability Administration Guide.

Deleting a Server

This section describes how to delete a server from the Cisco Unified Communications Manager database and how to add a deleted server back to the Cisco Unified Communications Manager cluster.

Before You Begin

In Cisco Unified Communications Manager Administration, you cannot delete the first node of the cluster, but you can delete subsequent nodes. Before you delete a subsequent node in the Find and List Servers window, Cisco Unified CM Administration displays the following message: "You are about to permanently delete one or more servers. This action cannot be undone. Continue?". If you click OK, the server gets deleted from the Cisco Unified CM database and is not available for use.


Tip When you attempt to delete a server from the Server Configuration window, a message that is similar to the one in the preceding paragraph displays. If you click OK, the server gets deleted from the Cisco Unified CM database and is not available for use.


Before you delete a server, consider the following information:

Cisco Unified Communications Manager Administration does not allow you to delete the first node in the cluster, but you can delete any subsequent node.

Cisco recommends that you do not delete any node that has Cisco Unified Communications Manager running on it, especially if the node has devices, such as phones, registered with it.

Although dependency records exist for the subsequent nodes, the records do not prevent you from deleting the node.

If any call park numbers are configured for Cisco Unified Communications Manager on the node that is being deleted, the deletion fails. Before you can delete the node, you must delete the call park numbers in Cisco Unified Communications Manager Administration.

If a configuration field in Cisco Unified Communications Manager Administration contains the IP address or host name for a server that you plan to delete, update the configuration before you delete the server. If you do not perform this task, features that rely on the configuration may not work after you delete the server; for example, if you enter the IP address or host name for a service parameter, enterprise parameter, service URL, directory URL, IP phone service, and so on, update this configuration before you delete the server.

If an application GUI, for example, Cisco Unity, Cisco Unity Connection, and so on, contains the IP address or host name for the server that you plan to delete, update the configuration in the corresponding GUIs before you delete the server. If you do not perform this task, features that rely on the configuration may not work after you delete the server.

The system may automatically delete some devices, such as MOH servers, when you delete a server.

Before you delete a node, Cisco recommends that you deactivate the services that are active on the subsequent node. Performing this task ensures that the services work after you delete the node.

Changes to the server configuration do not take effect until you restart Cisco Unified Communications Manager. For information on restarting the Cisco CallManager service, refer to Cisco Unified Serviceability Administration Guide.

To ensure that database files get updated correctly, you must reboot the cluster after you delete a server.

After you delete the node, access Cisco Unified Reporting to verify Cisco Unified Communications Manager removed the node from the cluster. In addition, access Cisco Unified Reporting, RTMT, or the CLI to verify that database replication is occurring between existing nodes; if necessary, repair database replication between the nodes by using the CLI.

Procedure


Step 1 Find the server by using the procedure in the "Finding a Server" section.

Step 2 From list of matching records, choose the server that you want to delete.

Step 3 Click the Delete Selected Item icon that displays in the tool bar in the upper, left corner of the window (or click the Delete Selected button that displays at the bottom of the window).


If you delete a subsequent node (subscriber) from Cisco Unified Communications Manager Administration and you want to add it back to the cluster, perform the following procedure:

Procedure for Adding a Deleted Server Back to the Cluster


Step 1 In Cisco Unified Communications Manager Administration, add the server by choosing System > Server.

Step 2 After you add the subsequent node to Cisco Unified Communications Manager Administration, perform an installation on the server by using the disk that Cisco provided in your software kit.


Tip For example, if you have a version 8.0(2) disk, perform a 8.0(2) installation on the node. If you have a disk with a compatible version of 6.1(3) on it, for example, use the disk to install Cisco Unified CM on the subsequent node; during the installation, choose the Upgrade During Install option when the installation displays the options.

Make sure that the version that you install on the subsequent node matches the version that runs on the first node (publisher) in the cluster.

If the first node in the cluster runs Cisco Unified Communications Manager 8.0(2) version and a service update (or engineering special), you must choose the Upgrade During Install option when the installation displays the installation options; before you choose this option, ensure that you can access the service update (or engineering special) image on DVD or a remote server. For more information on how to perform an installation, refer to installation documentation that supports your version of Cisco Unified Communications Manager.


Step 3 After you install Cisco Unified CM, configure the subsequent node, as described in the installation documentation that supports your version of Cisco Unified CM.

Step 4 Access the Cisco Unified Reporting, RTMT, or the CLI to verify that database replication is occurring between existing nodes; if necessary, repair database replication between the nodes.
