8.3 Force System Failover
You can use this item to verify your redundant network connections with the automatic
failover capability of an xStack Storage system that is equipped with dual controllers.
To force a system failover:
1. In the View panel, click the xStack Storage on which you want to force a failover.
2. In the System Actions panel, click Force System Failover . The pop-up confirmation
dialog shown below appears.
Figure 8-2. Confirm Force System Failover
3. Confirm the forced system failover by clicking “ Yes ” in response to the pop-up dialog
that appears.
A failover will be initiated on the xStack Storage system that you selected, and the
redundant controller will take over all system activities.
This procedure should only be used with extreme care, since a
subsequent failure on the remaining controller could result in loss of
access to your data.
After the failover completes, the system will immediately attempt to
return the controllers to a fully-redundant state.
