Disband a VCS X6.1 cluster
This process will remove all Cisco VCS peers from an existing cluster. FindMe and configuration
replication will be stopped, as will provisioning, and the cluster will be deleted from Cisco TMS.
replication will be stopped, as will provisioning, and the cluster will be deleted from Cisco TMS.
Each Cisco VCS will retain its configuration at the time the cluster was disbanded, and will function as
a stand-alone Cisco VCS.
a stand-alone Cisco VCS.
Warning: If any of the Cisco VCSs are left in operation after being removed from the cluster, calls
between endpoints registered to different Cisco VCSs that were once part of the same cluster will not
succeed. This is because after the cluster has been disbanded, the Cluster Subzone will no longer
exist and there will not be any link between the two Cisco VCSs over which calls can be routed. To
overcome this, you must create neighbor relationships between the Cisco VCSs so that there are
links between them.

If any Cisco VCS is not accessible, firstly remove it using the procedure “Remove an out-of-
service Cisco VCS from a VCS X6.1 cluster (permanently)”.
service Cisco VCS from a VCS X6.1 cluster (permanently)”.
If TMS is used, on Cisco TMS:
1. Select Systems > Navigator (and any required sub folders) then select the Master Cisco VCS.
2. Select the Clustering tab.
3. Clear the Enable TMS Agent Data Replication on all Cluster Peers.
4. Click Save Cluster Settings.
5. Select the TMS Agent tab.
6. Ensure that Enable TMS Agent Data Replication is not selected; if this needs changing, change
it and click Save Settings.
If TMS is used, on Cisco TMS, for every non-master Cisco VCS peer:
1. Select Systems > Navigator (and any required sub folders) then click on the non-master Cisco
VCS.
2. Select the TMS Agent tab.
3. Ensure that Enable TMS Agent Data Replication is not selected; if this needs changing, change
it and click Save Settings.
4. Repeat for all non-master Cisco VCS peers – Cisco TMS may require you to pause between
disabling each peer.
On each non-master Cisco VCS peer:
1. Log into the web interface.
2. From the Clustering page ( VCS configuration > Clustering):
a. Change the Cluster name to a unique ID for this Cisco VCS (ideally to the routable Fully
Qualified Domain Name used in SRV records that address this individual Cisco VCS, for
example "vcs1.example.com", "vcs2.example.com". etc. (See Appendix 10 – Cluster name
and DNS SRV records.))
Note: Do NOT use the process “Appendix 9 – Changing the cluster name (and keeping
FindMe accounts)” because FindMe accounts are to be left with the master peer of the
cluster that this Cisco VCS is being removed from.

Note: Do NOT use the process “Appendix 9 – Changing the cluster name (and keeping

b. Delete the Cluster pre-shared key.
c.
Delete all entries in the Peer x IP address fields.
3. Click Save.
