Complete this procedure after you finish changing the IP address, hostname, domain name or node name.
Step 1 If you have multiple clusters, reestablish the intercluster peers that you removed when you completed the pre-change tasks.
Step 2 If you disabled SSO prior to performing a procedure, you can enable it now. For information about how to enable SSO, see the "Single Sign-On Configuration" section of the Deployment Guide for Cisco Unified Presence.
Step 3 If the IP address for a server has been changed, update Cisco Unified Real-Time Monitoring Tool (RTMT) custom alerts and saved profiles:
•RTMT custom alerts that are derived from performance counters include the hard-coded server address. You must delete and reconfigure these custom alerts.
•RTMT saved profiles that have performance counters include the hard-coded server address. You must delete and re-add these counters and then save the profile to update it to the new address.
Step 4 Check and make any required configuration changes to other associated Cisco Unified Communications components, for example, SIP trunks on Cisco Unified Communications Manager.
Step 5 Start all network services that are listed under the CUP Services group. To do this, select Tools > Control Center - Network Services from the Cisco Unified Serviceability GUI. You must start the CUP Services network services in the following order:
1. Cisco UP Replication Watcher
2. Cisco UP Server Recovery Manager
3. Cisco UP Route Datastore
4. Cisco UP Login Datastore
5. Cisco UP SIP Registration Datastore
6. Cisco UP Presence Datastore
7. Cisco UP XCP Router
8. Cisco UP XCP Config Manager
9. Cisco UP OAM Manager
10. Cisco Client Profile Agent
11. Cisco UP Intercluster Sync Agent
12. Cisco UP Config Agent
Step 6 Start all feature services by selecting Tools > Control Center - Feature Services from the Cisco Unified Serviceability GUI. The order in which you start feature services is not important.
Step 7 If High Availability (HA) was disabled before the hostname or IP address change, enable HA on all subclusters. Select System > Cluster Topology in Cisco Unified Presence Administration. For more information about how to enable HA, see the Deployment Guide for Cisco Unified Presence.
Step 8 Complete the following steps to verify that Cisco Unified Presence is operating normally after the change:
a. From Cisco Unified Presence Administration, navigate to System > Cluster Topology and verify the following:
•If HA is enabled, verify that all HA nodes are in the Normal state.
•Verify that all services are started.
b. Run the System Troubleshooter from Cisco Unified Presence Administration (Diagnostics > System Troubleshooter) and ensure that there are no failed tests.
Step 9 You must run a manual Disaster Recovery System backup after you change the IP address or hostname of a node, because you cannot restore a node with a DRS file that contains a different IP address or hostname. The post-change DRS file will include the new IP address or hostname.
