Chapter5 Maintaining CiscoUnity Connection Server
Changing the IP Address or Hostname of a Unity Connection Server
•Change DHCP/DNS settings from Cisco Unified Operating System Administration> Settings
and select the applicable option from IP, and restart Unity Connection by running the CLI
command utils system restart.
•Disable DHCP on Unity Connection by running the CLI command set network dhcp and then
manually change the IP address by doing the procedure given below.
Note To change the IP address or hostname of a Unity Connection cluster, follow the steps mentioned in the
“Changing the IP Address or Hostname of a Unity Connection Server” section first on the publisher
server and then on the subscriber server.
Changing the IP Address or Hostname of a Unity Connection Server or Cluster
Do the following steps to change the IP address or Hostname of a standalone server or a cluster defined
by hostname. In case of a cluster, follow the steps first on the publisher server and then on the subscriber
server.
To Change the IP Address of a Standalone or a Cluster Server
Step1 Sign in to the standalone server or the publisher server using Real-Time Monitoring Tool. Expand Tool s>
Alert and select Alert Central. In the Systems tab, make sure the ServerDown is black. If ServerDown
is red, then resolve all the problems and change it to black. Repeat the same step for the subscriber server
(in case of a cluster).
Step2 Check the server status:
a. Sign in to CiscoUnity Connection Serviceability.
b. Expand Tool s and select Cluster Management.
c. On the Cluster Management page, check whether server status is Primary or Secondary. If there is
any other status value then resolve the problem.
Step3 Check the network connectivity and DNS server configuration by running the utils diagnose module
validate_network CLI command.
Step4 Backup the database using Disaster Recovery System. See the“Backing Up and Restoring CiscoUnity
Connection Components” chapter.
Step5 If intrasite, HTTPS, and SRSV networking is configured, remove the server from the Unity Connection
site. For instructions, see the Networking Guide for Cisco Unity Connection, Release 10.x, available at
http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/10x/networking/guide/10xcucnetx.h
tml.
Caution Re-adding a server to a Unity Connection site can be a time consuming process.
Step6 On a DNS server, change the DNS record of the Unity Connection server to the new IP address. Update
both the forward (A) and reverse (PTR) records.
Step7 On the standalone or publisher server, change the IP address, Hostname, and default gateway (if
applicable):
a. Sign in to Cisco Unified Operating System Administration.
b. From the Settings menu, select IP > Ethernet.
