Add an X7.1 VCS to a VCS X7.1 cluster
(Provisioning Extension mode)
Follow this process if you have an existing X7.1 cluster (of one or more peers) to which you want to
add another VCS peer. If you do not have an existing cluster, following the instructions in the section
“Create a new cluster of VCS X7.1 peers (Provisioning Extension mode – preferred)”.
add another VCS peer. If you do not have an existing cluster, following the instructions in the section
“Create a new cluster of VCS X7.1 peers (Provisioning Extension mode – preferred)”.
Note: You can have up to 6 VCSs, including the master VCS, in a cluster.
This process will add an X7.1 VCS to the cluster and replicate the cluster Master’s configuration onto
the VCS.
the VCS.
Prerequisites
If Device provisioning is enabled, or FindMe is managed by TMS the existing cluster of 1 or more
peers must already be running using Provisioning Extension mode.
peers must already be running using Provisioning Extension mode.
VCS clusters peers must all run the same version of code as the master, for example all X7.1.
Note: Only one VCS must be added to the cluster at a time.
On the Master VCS:
1. Ensure that the Master VCS does not list this new VCS peer in any of its neighbor zones or
traversal zones (VCS configuration > Zones then check each neighbor and traversal zone).
Note: The Master VCS will be the source of the configuration for this new VCS peer and all other
VCS peers in the cluster. When a VCS is added to the cluster, its configuration will be deleted and
replaced by that from the Master.
VCS peers in the cluster. When a VCS is added to the cluster, its configuration will be deleted and
replaced by that from the Master.
On the VCS to be added to the cluster:
1. Check that no other VCS (anywhere) has this VCS’s IP address in its Alternates or Clustering
Peers list.
2. Check that the VCS software version is identical to the version running on the Master and any
other cluster peers of the existing cluster (X7.1).
3. Backup the VCS (See Appendix 1 for details).
On the web interface of the VCS being added:
4. Review the configuration to ensure that the VCS has:
•
A valid Ethernet speed (System > Ethernet).
•
Valid IP address and IP gateway (System > IP).
•
The same set of Option keys as those installed on Master peer (Maintenance > Option
Keys).

Note: The number of call license keys may be different on different peers; all other license keys
must be identical on each peer.

•
At least one valid DNS server configured, and that if unqualified DNS names are used
elsewhere (e.g. for the NTP server), that the correct Domain name is also configured
(Domain name is added as a suffix to an unqualified DNS name to make it into an FQDN)
(System > DNS).

Note: <Local host name>.<DNS domain name> = FQDN of this Cisco VCS.
