You can add an existing resource group to the list of application resource groups for a protection group. Before you add an application resource group to a protection group, ensure that the following conditions are met:
The protection group is defined.
The resource group to add already exists on both clusters and is in an appropriate state.
The Auto_start_on_new_cluster property of the resource group is set to False. You can view this property by using the scrgadm command.
# scrgadm -pvv -g apprg | grep Auto_start_on_new_cluster |
Set the Auto_start_on_new_cluster property to False as follows:
scrgadm -c -g apprg1 -y Auto_start_on_new_cluster=False |
The application resource group must not have dependencies on resource groups and resources outside of this protection group. To add several application resource groups that share dependencies, you must add the application resource groups to the protection group in a single operation. If you add the application resource groups separately, the operation will fail.
The protection group can be activated or deactivated and the resource group can be either Online or Offline.
If the resource group is Offline and the protection group is Active after the configuration of the protection group has changed, the protection group's local state becomes Degraded.
If the resource group to add is Online and the protection group is deactivated, the request is rejected. You must activate the protection group before adding an activate resource group.
Log in to one of the cluster nodes.
You must be assigned the Geo Management RBAC rights profile to complete this procedure. For more information about RBAC, see Sun Cluster Geographic Edition Software and RBAC.
Add an application resource group to the protection group.
This command adds an application resource group to a protection group on the local cluster. Then the command propagates the new configuration information to the partner cluster if the partner cluster contains a protection group of the same name.
# geopg add-resource-group resource-group-list protection-group |
Specifies the name of the application resource group
You can specify more than one resource group in a comma-separated list.
Specifies the name of the protection group
For information about the names and values that are supported by Sun Cluster Geographic Edition software, see Appendix B, Legal Names and Values of Sun Cluster Geographic Edition Entities.
If the add operation is unsuccessful on the local cluster, the configuration of the protection group is not modified. Otherwise, the Configuration status is set to OK on the local cluster.
If the Configuration status is OK on the local cluster, but the add operation is unsuccessful on the partner cluster, the Configuration status is set to Error on the partner cluster.
After the application resource group is added to the protection group, the application resource group is managed as an entity of the protection group. Then the application resource group is affected by protection group operations such as start, stop, switchover, and takeover.
The following example illustrates how to add two application resource groups, apprg1 and apprg2, to tcpg:
# geopg add-resource-group apprg1,apprg2 tcpg |
