Understanding Your Failover Cluster
Resource Failure
Failover Clustering periodically checks if a resource is functioning properly
using either basic health check or thorough health check.
1 In the Failover Clustering console, right-click on the resource you want to
modify, and click Properties.
2 Under the Advanced Policies tab, you can define the Basic resource health
check interval and Thorough resource health check interval.
The Thorough resource health check interval requests a more thorough
check of the resource's state and therefore is typically longer than the Basic
resource health check interval.
NOTE:
Do not adjust the Basic resource health check interval and Through resource
health check interval settings unless instructed to do so by Dell Technical Support.
Adjusting the Resource Failure Policies
To define your desired response to a failure of your resource:
1 Right-click on the resource and click Properties and click the Policies tab.
2 In the Policies tab you can specify the Pending time-out value.
Pending time-out value is the length of time your resource can take to
change states between online and offline before the Cluster Service puts it
in a Failed state.
Additionally you can set the following failure policies:
• If the resource fails, you can choose not to restart the resource on the
current node or attempt restart on the current node. You can specify the
period for restarts and the maximum restarts in the specified time period.
• If restart is unsuccessful, you can choose to failover all resources along with
their dependent resources.
• If the cluster service exceeds the maximum number of restart attempts
within the specified time period and the failed resource has not been
restarted, Failover Clustering considers the resource to be failed.
NOTE:
To configure the Looks Alive, Is Alive, Threshold, and Period values for a
particular resource, see "Setting Resource Properties" on page 41.
NOTE:
Do not adjust the Basic resource health check interval and Through resource
health check interval settings unless instructed to do so by Dell technical Support.
