Determining Whether a Unity Connection 9.x Server is Defined by a Hostname or an IP Address

The procedure you use to change the IP address of a Unity Connection server depends on whether the server is defined by a hostname or by an IP address.

To Determine Whether a Unity Connection 9.x Server Is Defined by a Hostname or an IP Address


Step 1 On the server whose IP address you want to change, sign in to Cisco Unity Connection Administration.

Step 2 Expand System Settings, and select Cluster .

You go to the Cluster page even when no cluster is configured.

Step 3 Select Find to display a list of servers in the cluster.

Step 4 For the server whose IP address you want to change, if the value of the Hostname/IP Address column is a hostname, the server is defined by a hostname.

If the value of the Hostname/IP Address column is an IP address, the server is defined by an IP address.

Caution Do not change the IP address of a Unity Connection server during business hours. When a Unity Connection cluster is configured, both servers must be restarted for changes to take effect.

If the Unity Connection server is configured to get an IP address from a DHCP server, you cannot manually change the IP address of the server using Unity Connection processes. Instead, you must do one of the following:

  • Change DHCP/DNS settings, and restart the Unity Connection server by running the CLI command utils system restart .
  • Disable DHCP on the Unity Connection server by running the CLI command set network dhcp , and then manually change the IP address by doing the following procedure.

For more information on the CLI commands, see the applicable version of the Command Line Interface Reference Guide for Cisco Unified Communications Solutions at http://www.cisco.com/en/US/products/ps6509/prod_maintenance_guides_list.html .

To Change the IP Address of a Unity Connection 9.x Subscriber Server That Is Defined by an IP Address


Step 1 Review the list of associated components on which you also need to change the IP address of the Unity Connection server if those components reference Unity Connection by IP address. See the “Associated Components on Which the IP Address of a Unity Connection 9.x Server Must Be Changed” section.


Caution If associated components reference the Unity Connection server by IP address and if you do not change the IP address as applicable, the components will no longer be able to access the Unity Connection server.

Step 2 In the Real-Time Monitoring Tool (RTMT), confirm that the publisher and subscriber servers are running and available:

a. Using the RTMT, sign in to the publisher server.

b. In the left pane, under Tools, select Alert Central .

c. In the right pane, on the System tab, if ServerDown is black, skip to Step d.

If ServerDown is red, right-click ServerDown , and select Alert Details . Resolve the problem before continuing.

d. Repeat Step a. through Step c. on the subscriber server.

Step 3 On the subscriber server, sign in to Cisco Unified Serviceability, and check the status of the server:

a. From the Tools menu, select Cluster Management .

b. In the Server Status column, confirm that the value for the current server is either Primary or Secondary. If the Server Status column has any other value, resolve the problem before continuing.

Step 4 Check network connectivity and DNS server configuration by running the following CLI command:

admin: utils diagnose module validate_network

Log file: /var/log/active/platform/log/diag1.log

Starting diagnostic test(s)

===========================

test - validate_network : Passed

Diagnostics Completed

admin:

Step 5 Back up the server by using the Disaster Recovery System. See the Disaster Recovery System Administration Guide for Cisco Unity Connection Release 9.x at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/9x/drs_administration/guide/9xcucdrsag.html .

Step 6 On the publisher server, change the IP addresses of the subscriber server:

a. Sign in to Cisco Unity Connection Administration.

b. Expand System Settings, and select Cluster .

c. Select Find to display a list of servers in the cluster.

d. Select the name of the subscriber server.

e. Change the value of the Hostname/IP Address field to the new IP address.

f. Select Save .

Step 7 On the subscriber server, change the IP address of the subscriber server and, if applicable, the default gateway:

a. Sign in to Cisco Unified Operating System Administration.

b. From the Settings menu, select IP > Ethernet .

c. Under Port Information, change the value of the IP Address field and, if applicable, the Subnet Mask field.

d. If you are moving the publisher server to a different subnet that requires a new default gateway address, under Gateway Information, change the value of the Default Gateway field.

e. Select Save , and the system restarts.

Step 8 Sign in to the publisher server by using an SSH application, and run the CLI command utils system restart to restart the server, which updates the local name resolution files.

Step 9 In the RTMT, confirm that the publisher and subscriber servers are running and available:

a. Using the RTMT, sign in to the publisher server.

b. In the left pane, under Tools, select Alert Central .

c. In the right pane, on the System tab, if ServerDown is black, skip to Step d.

If ServerDown is red, right-click ServerDown , and select Alert Details . Resolve the problem before continuing.

d. Repeat Step a. through Step c. on the subscriber server.

Step 10 Update RTMT custom alerts and saved profiles.

    • RTMT custom alerts that are derived from performance counters include the hard-coded server IP address. You must delete and reconfigure the custom alerts.
    • RTMT saved profiles that have performance counters include the hard-coded server IP address. You must delete and readd the counters and then save the profiles to update them to the new IP address.

Step 11 Check associated components and change configurations as required. (Consult documentation for the affected products to determine how to make the required changes.) See the “Associated Components on Which the IP Address of a Unity Connection 9.x Server Must Be Changed” section.

Step 12 Back up the server by using the Disaster Recovery System. See the Disaster Recovery System Administration Guide for Cisco Unity Connection Release 9.x at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/9x/drs_administration/guide/9xcucdrsag.html .
