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.
