Bug ID 4378553

Problem Summary: A resource group's Nodelist property is an ordered list of nodes that can master the resource group, with the most-preferred node listed first. The Resource Group Manager should always host a resource group on the most-preferred node that is available. However, when an administrator reboots the cluster (when all nodes are rebooting at once), managed resource groups might end up being mastered on nodes other than the most-preferred node. This problem occurs only upon reboot of the entire cluster.

Workaround: After rebooting the cluster, use the scswitch command to switch resource groups onto the desired nodes. The Nodelist preference order will be enforced automatically from that point onward, as long as the cluster remains up.
