selected from the Server: Monitoring > Configure Failover dialog (default

If installed in a WAN environment, you must manually select Failover from

Primary server to Secondary server if channel heartbeat is lost for failover

timeout in the Server: Monitoring > Configure Failover dialog.

Important: Prior to starting the Installation Verification process, ensure that a

known good backup of the primary server exists and examine the Windows

event logs for recent critical errors.

SolarWinds provides an executable, nfavt.exe, to emulate conditions that

result in auto-switchover so you can verify that your SolarWinds Failover Engine

installation performs as expected. This section guides you through the steps

necessary to perform this verification.

Steps to Perform

Important: If you encounter errors and or find it necessary to back out the

changes made by this exercise, you can stop at any point and perform the steps

described in the Back-out Procedure (Auto-switchover) to return the Pair to its
