Failing over and failing back

As previously mentioned, when a node goes offline, all resources dependent on that node are
automatically failed over to another node. Processing continues, but in a reduced manner, because
all operations must be processed on the remaining node(s). In clusters containing more than two
nodes, additional fail over rules can be applied. For instance, groups can be configured to fail
over different nodes to balance the additional work load imposed by the failed node. Nodes can
be excluded from the possible owners list to prevent a resource from coming online on a particular
node. Lastly the preferred owners list can be ordered, to provide an ordered list of failover nodes.
Using these tools, the failover of resources can be controlled with in a multinode cluster to provide
a controlled balanced failover methodology that balances the increased work load.
Because operating environments differ, the administrator must indicate whether the system will
automatically fail the resources (organized by resource groups) back to their original node or will
leave the resources failed over, waiting for the resources to be moved back manually.
NOTE:
If the storage system is not set to automatically fail back the resources to their designated
owner, the resources must be moved back manually each time a failover occurs.

Restarting one cluster node

CAUTION:
in the cluster are functioning normally. Adequate warning should be given to users connected to
resources of the node being restarted. Attached connections can be viewed through Server Manager
on the storage system Desktop using Terminal Services. From Failover Cluster Manager, select a
file server role and then view the shares for that role.
If the printer spool resource is added to an existing group with a physical resource,
Restarting a cluster node should be done only after confirming that the other node(s)
