Add an X6.0 VCS to a VCS X6.0 cluster
Follow this process if you have an existing X6.0 cluster (of one or more peers) to which you want to
add another Cisco VCS peer. If you do not have an existing cluster, following the instructions in the
section “Create a new cluster of VCS X6.0 peers”.
add another Cisco VCS peer. If you do not have an existing cluster, following the instructions in the
section “Create a new cluster of VCS X6.0 peers”.
Note: You can include up to 6 Cisco VCSs, including the master Cisco VCS, in a cluster.
This process will add an X6.0 VCS to the cluster and replicate the cluster Master’s configuration onto
the Cisco VCS.

Note: Cisco VCS clusters peers must all run the same version of code as the master, for example all

On the Master Cisco VCS:
1. Ensure that the Master Cisco VCS does not list this new Cisco VCS peer in any of its neighbor
zones or traversal zones (VCS Configuration > Zones then check each neighbor and traversal
zone).

Note: The Master Cisco VCS will be the source of the configuration for this and all Cisco VCS peers
in the cluster. When a Cisco VCS is added to the cluster, its configuration will be deleted and
replaced by that from the Master.
in the cluster. When a Cisco VCS is added to the cluster, its configuration will be deleted and
replaced by that from the Master.
On the Cisco VCS to be added to the cluster:
1. Check that no other Cisco VCS (anywhere) has this Cisco VCS’s IP address in their Alternates or
Clustering Peers list.
2. Check that the Cisco VCS is running X6.0 software and that the software version is identical to
the version running on the Master and any other cluster peers of the existing cluster.
3. Backup the Cisco VCS (See Appendix 1 for details).
On the web interface of the Cisco VCS being added:
4. Review the configuration to ensure that the Cisco 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).
