Perform this procedure to add an existing resource group to the list of application resource groups for a protection group.
The protection group can be activated or deactivated and the resource group can be either online or unmanaged.
If the resource group is unmanaged and the protection group is activated after the configuration of the protection group has changed, the local state of the protection group becomes Error.
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 online resource group.
Before You Begin
Ensure that the following conditions are met:
The protection group is defined.
The resource group to be added already exists on both clusters and is in an appropriate state.
For more information about RBAC, see Securing Geographic Edition Software in Oracle Solaris Cluster Geographic Edition Installation and Configuration Guide .
# chmod A+user:username:rwx:allow /var/cluster/geo
The /var/cluster/geo directory must have the correct access control lists (ACL) applied for compatibility between the Geo Management RBAC rights profile and Oracle ZFS Storage Appliance software.
# clresourcegroup show -p Auto_start_on_new_cluster resource-group
If necessary, change the property value to False.
# clresourcegroup set -p Auto_start_on_new_cluster=False resource-group
# geopg list protection-group | grep -i external_dependencies_allowed
If necessary, change the property value to True.
# geopg set-prop -p External_dependencies_allowed=TRUE protection-group
If the protection group is offline, the application resource group must also be offline before it can successfully be added to the protection group.
# clresourcegroup offline resource-group
# geopg add-resource-group application-resource-group protection-group [-p external_dependencies_allowed=TRUE]
Specifies the name of an application resource group. You can specify more than one resource group in a comma-separated list.
Specifies the name of the protection group.
Permits the application resource group to have dependencies on resource groups and resources that are outside of the protection group.
The command adds an application resource group to a protection group on the local cluster. Then, if the partner cluster contains a protection group of the same name, the command propagates the new configuration information to the partner cluster.
For information about the names and values that are supported by Geographic Edition software, see Appendix B, Legal Names and Values of Geographic Edition Entities, in Oracle Solaris Cluster Geographic Edition System Administration Guide .
After the application resource group is added to the protection group, the application resource group is managed as an entity of the protection group. The application resource group is now affected by protection group operations such as start, stop, switchover, and takeover.
# clresourcegroup online application-resource-group
The following example adds two application resource groups, apprg1 and apprg2, to the zfssa-pg protection group.
# geopg add-resource-group apprg1,apprg2 zfssa-pg
Troubleshooting
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.
