Checking High Availability Status
147
If the backup Firewall has taken over for the primary, for example, in the
event of a failure to the primary Firewall, the first line in the status
window indicates that the backup Firewall is currently Active.
Check the status of the backup Firewall by logging into the LAN IP
Address of the backup Firewall. If the primary Firewall is operating
normally, the status window will indicate that the backup Firewall is
currently Idle. If the backup has taken over for the primary, this window
will indicate that the backup is currently Active.
In the event of a failure in the primary Firewall, you may access the Web
interface of the backup Firewall at the primary Firewall’s LAN IP Address
or at the backup Firewall’s LAN IP Address. The primary Firewall will not
be accessible until the primary Firewall has become Active again.
E-Mail Alerts
Indicating Status
Change
If you have configured the primary Firewall to send e-mail alerts, you will
receive an alert e-mail when there is a change in the status of the High
Availability pair. For example, when the backup Firewall takes over from
the primary after a failure, an e-mail alert will be sent indicating that the
backup has transitioned from Idle to Active. If the primary Firewall
subsequently resumes operation after that failure, and Preempt Mode has
been enabled, the primary Firewall will take over and another E-mail alert
will be sent to the administrator indicating that the primary has
preempted the backup.
View Log
The Firewall also maintains an event log that displays these High
Availability events in addition to other status messages and possible
security threats. This log may be viewed with a browser using the Firewall
Web interface or it may be automatically sent to the administrator’s
e-mail address.
To view the Firewall log, click the Log button on the left side of the
browser window and then click on the View Log tab at the top of the
window. A window similar to the following will be displayed.
