5. If Microsoft OCS/Lync B2BUA was used in the cluster, go to the Microsoft OCS/Lync B2BUA
configuration page (Applications > B2BUA > Microsoft OCS/Lync > Configuration).

and click Save.
6. Restart the VCS (Maintenance > Restart and then click Restart System).
On the Master VCS:
1. Log into the web interface.
2. On the Clustering page (VCS configuration > Clustering) delete the IP address of the VCS that
has been removed.
3. If the VCS being removed is not the last field in the list, move any other IP addresses up the list
so that there are no empty fields between entries.
4. If the master VCS peer’s IP address has been moved up the list in the previous step, alter the
Configuration master value to match its new location.
5. Click Save.
On all the remaining non-master VCS peers:
1. Log into the web interface.
2. On the Clustering page (VCS configuration > Clustering) edit the Peer x IP address and
Configuration master fields so that they are identical to those configured on the Master VCS.
3. Click Save.
4. Repeat for all remaining non-master VCS peers until they all have identical clustering
configuration.
On other devices:
1. If you have any other VCSs, Gatekeepers or Border Controllers neighbored (or connected via a
traversal zone) to this cluster of VCS peers, ensure their zone configuration for this cluster is
updated to exclude the address of the removed peer.
updated to exclude the address of the removed peer.
2. If you have any endpoints registering to the VCS that has now been removed, change the
configuration of the endpoint (or the configuration of the DNS server entry that points to the
cluster peers) so that they register to one of the remaining clustered VCS peers instead.

Caution: The removed VCS will retain its configuration at the time it is removed from the cluster, and
will continue to function as a non-clustered VCS. It is recommended that after it has been removed
from the cluster it is taken out of service (e.g. perform a factory reset – as documented in ”Before
reconnecting the out-of-service VCS back to the network” later in this document, or perform
xcommand DefaultValuesSet Level: 2

Reconfigure TMS
If TMS is used and TMS Agent is in Legacy mode, on TMS:
1. Select Systems > Navigator (and any required sub folders) then select the Master VCS.
2. Select the Clustering tab.
3. Click Update Cluster in TMS.
After the removal
If TMS is not used or TMS is in Provisioning Extension mode, skip this section, there are no diagnostic
