VCS alarms and warnings
“Cluster name not configured: if FindMe or clustering are in use a cluster
name must be defined”
name must be defined”
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 VCS cluster, for example "cluster1.example.com". (See
this VCS cluster, for example "cluster1.example.com". (See

This may be:

n
"Cluster replication error: this peer's configuration conflicts with the master's configuration, manual

If a non-master VCS reports an alarm: “Cluster replication error – <details> synchronization of configuration”
On that non-master VCS:
1. Log in as admin on an SSH or other CLI interface.
2. At the command prompt type:
xcommand ForceConfigUpdate
This will delete the non-master VCS configuration and then force it to update its configuration from the
master VCS.
This will delete the non-master VCS configuration and then force it to update its configuration from the
master VCS.
CAUTION
: Only use this command if the configuration on the master VCS is known to be in a good state.
We recommend that you take a backup before running this command.
"Cluster replication error: the NTP server is unreachable"
Configure an accessible NTP server on the VCS

page.
"Cluster replication error: the local VCS does not appear in the list of
peers"

Check and correct the list of peers for this VCS on the master VCS, and copy to all other VCS peers
