How to Add a Node to a Scalable Resource Group

  1. 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.

    See Step 1 through Step 4 in the following procedure for details.

  2. 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
    
    -c

    Changes a resource group.

    -g resource-group

    Specifies the name of the resource group to which the node is being added.

    -h nodelist

    Specifies a comma-separated list of nodes that can master the resource group.

  3. (Optional) Update the Load_balancing_weights property of the scalable resource to assign a weight to the node that you want to add to the resource group.

    Otherwise, the weight defaults to 1. See the scrgadm(1M) man page for more information.
