Ensure that the node list of the SAP xserver resource group and the liveCache resource group contain the same nodes.
Ensure that the value of desired_primaries and maximum_primaries of the SAP xserver resource is equal to the number of nodes listed in the nodelist parameter of the liveCache resource.
