Controlling Failover

Controlling Failover

This sections describes how to control and monitor failover. This section includes the following topics:

•Forcing Failover, page66-13

•Disabling Failover, page66-13

•Restoring a Failed Unit, page66-13

Forcing Failover

To force the standby unit to become active, perform the following steps:

Step1 Choose Monitoring > Properties > Failover > Status.

Step2 Click one of the following buttons:

•Click Make Active to make the unit the active unit.

•Click Make Standby to make the other unit in the pair the active unit.

Disabling Failover

To disable failover, perform the following steps:

Step1 Choose Configuration > Device Management > High Availability > Failover.

Step2 Uncheck the Enable Failover check box.

Restoring a Failed Unit

To restore a failed unit to an unfailed state, perform the following steps:

Step1 Choose Monitoring > Properties > Failover > Status.

Step2 Click Reset Failover.
