How to Remove a Node From a Failover Resource Group That Contains Shared Address Resources

In a failover resource group that contains shared address resources that scalable services use, a node can appear in the following locations.

• The node list of the failover resource group

• The auxnodelist of the shared address resource

To remove the node from the node list of the failover resource group, follow the procedure How to Remove a Node From a Failover Resource Group.

To modify the auxnodelist of the shared address resource, you must remove and re-create the shared address resource.

If you remove the node from the failover group's node list, you can continue to use the shared address resource on that node to provide scalable services. To continue to use the shared address resource, you must add the node to the auxnodelist of the shared address resource. To add the node to the auxnodelist, perform the following steps.

You can also use the following procedure to remove the node from the auxnodelist of the shared address resource. To remove the node from the auxnodelist, you must delete and re-create the shared address resource.

Steps

1. Switch the scalable service resource offline.

2. Remove the shared address resource from the failover resource group.

3. Create the shared address resource.

   Add the node ID or node name of the node that you removed from the failover resource group to the auxnodelist.
