VCS Alarms and Warnings
"Cluster name not configured: if FindMe or clustering are in use a cluster 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
cluster, for example "cluster1.example.com". (See
).
"Cluster replication error: <details> manual synchronization of configuration is required"
This may be:
■
"Cluster replication error: manual synchronization of configuration is required"
■
"Cluster replication error: cannot find primary or this subordinate's peer configuration file, manual
synchronization of configuration is required"
synchronization of configuration is required"
■
"Cluster replication error: configuration primary ID is inconsistent, manual synchronization of configuration is
required"
required"
■
"Cluster replication error: this peer's configuration conflicts with the primary's configuration, manual
synchronization of configuration is required"
synchronization of configuration is required"
If a subordinate VCS reports an alarm: "Cluster replication error – <details> synchronization of configuration"
On that subordinate 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 subordinate VCS configuration and then force it to update its configuration from the
primary VCS.
primary VCS.
Caution:
Only use this command if the configuration on the primary 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 System > Time 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 primary VCS, and copy to all other VCS peers (System >
Clustering).

"Cluster replication error: automatic replication of configuration has been temporarily disabled
because an upgrade is in progress"
because an upgrade is in progress"
Wait until the upgrade has completed.
"Invalid clustering configuration: H.323 mode must be turned On - clustering uses H.323
