HP StorageWorks P9000 Cluster Extension Software Administrator Guide (TB534-96009, February 2011)

8. Add a resource colocation constraint between the resource group ID assigned in Step 2 and
the last resource in the group hierarchy.
9. Set location constraints for the group ID to achieve the required failover order for the group.
10. Set the operation defaults to control failover behavior. To specify that when a resource fails,
the resources attempts to restart on the same node or another node in the cluster, use the
following settings:
ValueName
nothingrequires
restarton-fail
30timeout
11. Set the migration-threshold value. This value defines the number of failures that can occur on
a node before the node becomes ineligible to host the resource and the resource fails over to
another node. Set this value to 1 for P9000 Cluster Extension.
12. Disable automatic failback by using resource constraints and setting resource-stickiness to the
lowest value compared with the other resource location constraints.
