A scalable service is configured as two resource groups, as follows.
One resource group is a scalable group that contains the scalable service resource.
One resource group is a failover group that contains the shared address resources that the scalable service resource uses.
Additionally, the RG_dependencies property of the scalable resource group is set to configure the scalable group with a dependency on the failover resource group. See Appendix A, Standard Properties for details on this property.
See the Sun Cluster 3.0 12/01 Concepts document for details about scalable service configuration.
Removing a node from the scalable resource group causes the scalable service to no longer be brought online on that node. To remove a node from the scalable resource group, perform the following steps.
Remove the node from the list of nodes that can master the scalable resource group (the nodelist resource group property).
# scrgadm -c -g scalable-resource-group -h nodelist |
Changes a resource group.
Specifies the name of the resource group from which the node is being removed.
Specifies a comma-separated list of nodes that can master this resource group.
(Optional) Remove the node from the failover resource group that contains the shared address resource.
See "How to Remove a Node From a Failover Resource Group That Contains Shared Address Resources" for details.
(Optional) Update the Load_balancing_weights property of the scalable resource to remove the weight of the node that you want to remove from the resource group.
See the scrgadm(1M) man page for more information.
