Cisco Cisco Expressway
"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.
2.
.
3.
Restore that Expressway’s database by restoring a backup taken on that Expressway previously.
4.
.
A second method is possible if the database does not recover:
1.
Take a system snapshot and provide it to TAC.
2.
.
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.
5.
.
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.
Cisco TMS Warnings
Cisco TMS Cluster Diagnostics
If Cisco TMS cluster diagnostics reports a difference in configuration on Expressway peers, it is comparing the output
of
of
https://<ip address>/alternatesconfiguration.xml
for each Expressway.
To manually check the differences, on a Unix / Linux system, run:
wget --user=admin --password=<password> --no-check-certificate https://<IP or FQDN of
Expressway
>/alternatesconfiguration.xml
for each of the Expressway peers, then use
diff
to check for differences.
Expressway’s External Manager Protocol Keeps Getting Set to HTTPS
Cisco TMS can be configured to force specific management settings on connected systems. This includes ensuring
that a Expressway uses HTTPS for feedback. If enabled, Cisco TMS will (on a time period defined by Cisco TMS) re-
configure the Expressway’s System > External manager Protocol to HTTPS.

for information about how to set up certificates.
Cisco TMS will force HTTPS on Expressway if:
■
TMS Services > Enforce Management Settings on Systems = On (Administrative Tools > Configuration >
Network Settings)
and

and
■
Secure-Only Device Communication > Secure-Only Device Communication = On (Administrative Tools >
Configuration > Network Settings)

Set Enforce Management Settings on Systems to Off if Cisco TMS does not need to force the management settings.
Set Secure-Only Device Communication to Off if it is unnecessary for Expressway to provide feedback to Cisco TMS
using HTTPS (if HTTP is sufficient).
