Testing failover
The failover process, including pre-failover and post-failover script processing, can be tested at any time. To force
unavailability, disconnect the network cable from a monitored machine, wait for the
Time to Fail counter to decrease to zero
and failover begins. To avoid the countdown delay, highlight the monitored machine name in the Failover Control Center
window and select Failover.
Failover manual intervention
The Require User Intervention to Initiate Failover option generates a prompt through the Failover Control Center. The
prompt directs the administrator to click
OK to proceed with the failover or Cancel to cancel the failover process. Failover
can be initiated when appropriate from the Failover Control Center
NOTE: Remove the source from the network before testing failover. If the source is still on the network, an IP address
conflict will occur.
NOTE: If the Failover Control Center is not running when a failure occurs, the manual intervention dialog box will
appear the next time the Failover Control Center is started.
When a failure occurs, an alert is forwarded to the Linux system log. You can then start the Failover Control
Center and respond to the Manual Intervention Required prompt.
If SNMP is installed and configured, an SNMP trap is also generated. When using a third-party SNMP manager,
an e-mail or page can be generated to notify you of the failure.
