Failing over data workloads, application workloads
configured for identity failover, and cluster workloads
The failover process, including 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.
Note: If the target is a cluster, you must click Failover from the active node of the target
cluster. After failover is complete, click Failover on the passive node(s). This
ensures that all nodes of the target cluster are aware of the failover so the source
cannot overwrite the target's data on any of the node(s) of the target cluster.
If Manual Intervention is enabled, the Failover Control Center will prompt you when a
failure occurs. Click Cancel to abort the failover process. (If necessary, you can initiate
failover later from the Failover Control Center.) Click OK to proceed with failover.
Note: If the Failover Control Center is not running at the time the 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 Windows event log. You can
then start the Failover Control Center and respond to the manual intervention
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.
You will be prompted to specify what data you want to use on the target.
