Ensure that the same cluster name is configured on each VCS in the cluster.
The Cluster name should be the routable Fully Qualified Domain Name used in SRV records that
address this Cisco VCS cluster, for example "cluster1.example.com". (See Appendix 10 – Cluster
name and DNS SRV records).

“Cluster replication error: the Master peer is unreachable”
If Cisco VCS reports an alarm: “Cluster replication error: the Master peer is unreachable”:
from a root login, check the directory /tmp/x5/peerconfiguration
it should have directories for each peer, e.g. if 2 peers it should have directories 1 and 2
it should also have a file ‘clustermaster’
cat clustermaster
tells you the master
If the file clustermaster does not exist on any member of the cluster it must be created. This can
be done by changing all Cisco VCSs in the cluster to use a new Cisco VCS as the cluster master
and then returning them all to use the preferred master.
be done by changing all Cisco VCSs in the cluster to use a new Cisco VCS as the cluster master
and then returning them all to use the preferred master.
Do this on each Cisco VCS in the cluster using the web interface:
1. Go to VCS configuration > Clustering.
2. From the Configuration master drop down select the a new cluster master (make sure that this
is the same on all Cisco VCSs in the cluster).
3. Click Save.
4. Repeat for all Cisco VCSs in the cluster
then, on each Cisco VCS in the cluster:
5. From the Configuration master drop down select the preferred cluster master on all Cisco VCSs
in the cluster.
6. Click Save.
7. Repeat for all Cisco VCSs in the cluster.

1. Check the Event Log.
If it reports:
<Date> logger: Event="Application Warning" Detail="Cluster watchdog

then the base configuration file is too large for the automated process to copy. A manual copy can
be carried out to fix this.

2. On the Cisco VCS reporting this issue, login to the Cisco VCS as root and type:
