Modifying failover and failback settings, including preferred owners
You can adjust the failover settings, including preferred owners and failback settings, to control how the cluster responds when the application or service fails. You can configure these settings on the property sheet for the clustered service or application (on the General tab or the Failover tab). The following table provides examples that illustrate how these settings work.
General tab, Preferred owner: Node1
Failover tab, Failback setting: Allow failback (Immediately)
If the service or application fails over from Node1 to Node2, when Node1 is again available, the service or application will fail back to Node1.
Failover tab, Maximum failures in the specified period: 2
Failover tab, Period (hours): 6
In a six-hour period, if the application or service fails no more than twice, it will be restarted or failed over each time. If the application or service fails a third time in the six-hour period, it will be left in the failed state.
The default value for the maximum number of failures is n-1, where n is the number of nodes. You can change the value, but we recommend a relatively low value, so that if multiple node failures occur, the application or service will not be moved between nodes indefinitely.
List of topics about modifying settings
The following topics provide details about settings that you can modify for a clustered service or application:
- Add Storage for a Clustered Service or Application (For information about adding a disk to the cluster itself, so that the disk is available for adding to a clustered service or application, see Add Storage to a Failover Cluster).
- Add a Resource to a Clustered Service or Application
- Modify the Failover Settings for a Clustered Service or Application
- Modify the Virtual Machine Settings for a Clustered Virtual Machine
- Create a Shared Folder in a Clustered File Server
- Configure the Print Settings for a Clustered Print Server
- Configuring a Service or Application for High Availability
