The following table identifies how the visual indicators change as the status of failover changes.
Updating shares manually
Share information can be manually updated from the Failover Control Center window. To manually
update the share information, highlight a source machine in the Monitored Machines tree and click
the Update Shares button.
Testing failover
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.

changes from green to yellow, indicating that the target has not received a response from the
source. The yellow bullet is a caution signal. If a response from the source is received, the
countdown resets and the bullets change back to green. If the countdown reaches zero without
the target receiving a response from the source, failover begins.

NOTE: If the target is a cluster, you will need to determine the active node and failover from that
node. Then you will need to failover from each of the other nodes also. This prevents data
corruption if the owning node changes while the source is failed over.
