“Expressway database failure: Please contact your Cisco support

representative”
The support representative will help you work through the following steps:
1. Take a system snapshot and provide it to your support representative.
3. Restore that Expressway’s database by restoring a backup taken on that Expressway previously.
A second method is possible if the database does not recover:
1. Take a system snapshot and provide to TAC.
3. Log in as root and run clusterdb_destroy_and_purge_data.sh
4. Restore that Expressway’s database by restoring a backup taken on that Expressway previously.
Note: clusterdb_destroy_and_purge_data.sh is as dangerous as it sounds – only use this
command in conjunction with instructions from your support representative.

Cluster with Advanced Networking is not replicating
correctly
correctly
Expressway-Es with Advanced Networking are only designed to replicate through their LAN 1 interface.
Ensure that the Peer x IP Address entries specified in
Ensure that the Peer x IP Address entries specified in
System > Clustering
all refer to LAN 1 interfaces.
Also, this replicating interface (LAN 1) must not have NAT enabled on it.
Cluster with static NAT is not replicating correctly
When using Expressway-Es with static NAT, the cluster replication must occur on the LAN interface which
is not behind the NAT device. Therefore LAN interface 1 must be the non-NAT interface and the Peer x IP
Address entries specified in
is not behind the NAT device. Therefore LAN interface 1 must be the non-NAT interface and the Peer x IP
Address entries specified in
System > Clustering
must all refer to LAN 1 interfaces. LAN interface 2 must
be configured for static NAT.
