Description
Occasionally a service group failover needs to be avoided while performing testing or system maintenance. To avoid service group failover, the following options are available:- Restart the failed resources
Set the RestartLimit attribute to greater than 1 for a resource type which allows a resource to be restarted on the current node, instead of faulting and failing over.
- Freeze the relevant service group
Note: A group can be frozen to prevent it from failing over even if a critical resource fails. The persistent option maintains the frozen state after a reboot if this change is saved to the configuration.
- Set resources to non-critical
The Critical attribute for a resource defines whether a service group fails over when the resource faults. If a resource is configured as non-critical (by setting unchecking the attribute) and no resources depending on the failed resource are critical, the service group will not fail over.
