Cluster resource priorities control the load order of a resource relative to other cluster resources on the same cluster node when bringing up a cluster, or during a failover or failback. This is useful for ensuring that the most critical resources load first and are available to users before less critical resources.
The Resource Priority setting controls the order in which multiple resources start on a given node when the cluster is brought up or during a failover or failback. For example, if a node fails and two resources fail over to another node, the resource priority determines which resource loads first.
In iManager, select> .

Arrows: Select a resource in the list by clicking on it, then click the up-arrow or down-arrow buttons to move the resource up or down in the list. The page refreshes between each click on an arrow.
Edit: Open the Resource Priority Edit function by clicking thepen icon, list the resources in the preferred load order with one resource per line, then click to accept the revised order.
