Expressway Alarms and Warnings
"Cluster name not configured: if clustering is in use a cluster name must be defined"
Ensure that the same cluster name is configured on each Expressway in the cluster.
The Cluster name should be the routable Fully Qualified Domain Name used in SRV records that address this
Expressway cluster, for example "cluster1.example.com". (See
Expressway 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 master or this slave's peer configuration file, manual synchronization of
configuration is required"
configuration is required"
■
"Cluster replication error: configuration master ID is inconsistent, manual synchronization of configuration is
required"
required"
■
"Cluster replication error: this peer's configuration conflicts with the master's configuration, manual
synchronization of configuration is required"
synchronization of configuration is required"
If a subordinate Expressway reports an alarm: "Cluster replication error – <details> synchronization of configuration"
On that subordinate Expressway:
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 Expressway configuration and then force it to update its configuration from the
primary Expressway.
primary Expressway.
Caution:
Only use this command if the configuration on the primary Expressway 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 Expressway System > Time page.
"Cluster replication error: the local Expressway does not appear in the list of peers"
Check and correct the list of peers for this Expressway on the primary Expressway, and copy to all other Expressway
peers (System > Clustering).
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
communications between peers"
communications between peers"
Ensure that H.323 mode is on (see Configuration > Protocols > H.323).
