Set Start, Failover, and Failback Modes

Use this property page to set the start, failover and failback modes for this resource to either manual or auto.

Ignore Quorum
Check this box if you don't want the cluster-wide timeout period and node number threshold enforced. Check this box to ensure the resource is launched immediately on any server in the Assigned Nodes list as soon as any server in the list is brought online.

Start Mode
Set the start mode to Manual to prevent resources from loading when the cluster is first brought up. Setting the start mode to Manual allows you to manually start resources on specific servers when you want, instead of having them automatically start when servers in the cluster are brought up. Set the start mode to Auto to have resources automatically load on designated servers when the cluster is first brought up. If all servers in the cluster are brought down, the start mode setting will be used to determine if resources should load when servers in the cluster are brought up again.

Failover Mode
Set the failover mode to Manual if you want to intervene after a failure occurs and before the resource is moved to another node. Set the failover mode to Auto if you want the resource to automatically move to the next server in the Assigned Nodes list in the event of a hardware or software failure.

Master Only
Check this box to ensure the resource runs only on the master node in the cluster. If the master node in the cluster fails, the resource will failover to whichever node becomes the master.

Failback Mode
Set the failback mode to Manual to prevent the resource from moving back to its preferred node when that node is brought back online, until you are ready to allow it to happen. Set the failback mode to Auto to have the application or resource automatically move back to its preferred node when the preferred node is brought back online. Set the failback mode to Disable to prevent the resource from moving back to its preferred node. Setting the failback mode to Disable allows the resource to continue running in an online state on the node it has failed to.

The preferred node is the first server in the nodes list on the Nodes property page. The resource will not failback to any other servers in the cluster except the preferred node.
