Disbanding a VCS cluster
This process removes all 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.

Each VCS will retain its configuration at the time the cluster was disbanded, and will function as a stand-
alone VCS.
alone VCS.
CAUTION
: If any of the VCSs are left in operation after being removed from the cluster, calls between
endpoints registered to different 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 VCSs over which calls can be routed. To overcome this, you must create neighbor
relationships between the VCSs so that there are links between them.

Before you start:
If Cisco TMS is used (in Provisioning Extension mode):
1. Select
Systems > Navigator
(and any required sub folders), then click on any VCS in the cluster.
2. Select the
Provisioning
tab.
3. Disable all 4 services (clear tick boxes).
4. Click Save.
On each non-master VCS peer:
1. Log into the web interface.
2. Go to
System > Clustering
:
a. Change the Cluster name to a unique ID for this VCS (ideally to the routable Fully Qualified Domain
Name used in SRV records that address this individual VCS, for example "vcse1.example.com". See
.)
b. Delete the Cluster pre-shared key.
c. Delete all entries in the Peer x IP address fields.
c. Delete all entries in the Peer x IP address fields.
3. Click Save.
Note that:

All previous FindMe users will still be available on this removed VCS. Remove them manually (
Users >
FindMe accounts
) if required.

An alarm similar to that shown below may appear on the web interface and CLI of the VCS being
removed. This is not a problem, the alarm will be cleared when the VCS is restarted:

4. If Microsoft Lync B2BUA was used in the cluster:
a. Go to
Applications > B2BUA > Microsoft Lync > Configuration
.
b. If Microsoft Lync B2BUA is Enabled, change it to Disabled and click Save.
5. Restart the VCS (go to
Maintenance > Restart options
, then click Restart and confirm OK).
If multiple peers need restarting: restart each peer in turn, waiting for the peer to be accessible through the
web interface before restarting the next peer.

6. Repeat for each non-master VCS.
