For each network resource that a scalable resource in the resource group uses, make the resource group where the network resource is located run on the new node.
Add the new node to the list of nodes that can master the scalable resource group (the nodelist resource group property).
This step overwrites the previous value of nodelist, and therefore you must include all of the nodes that can master the resource group here.
# scrgadm -c -g resource-group -h nodelist
Changes a resource group
Specifies the name of the resource group to which the node is being added
Specifies a comma-separated list of the names of the nodes that can master the resource group
(Optional) Update the scalable resource's Load_balancing_weights property to assign a weight to the node that you are adding to the resource group.
Otherwise, the weight defaults to 1. See the scrgadm(1M) man page for more information.
