During protection group validation, the Sun StorEdge Availability Suite 3.2.1 data replication layer validates the application resource groups and the data replication entities as follows:
Verifies that a application resource group in the protection group has its Auto_start_on_new_cluster property set to False.
Setting the Auto_start_on_new_cluster property to False prevents the Sun Cluster resource group manager from automatically starting the resource groups in the protection group. Therefore, after the Sun Cluster Geographic Edition software restarts and communicates with the remote cluster to ensure that the remote cluster is running and that the remote cluster is the secondary cluster for that resource group. The Sun Cluster Geographic Edition software does not automatically start the resource group on the primary cluster.
Application resource groups should be online only on primary cluster when the protection group is activated.
Verifies that the Nodelist property of an application resource group that has affinities with a device group defined by the HAStoragePlus resource contains the same entries in identical order to the Nodelist property of the protection group.
Verifies that the Nodelist property of a device group in the protection group contains the same entries in identical order to the Nodelist property of the protection group.
Verifies that a lightweight resource group is created for each device group in the protection group. Each lightweight resource group contains two resources, a logical hostname resource and a HAStoragePlus resource. For more information about lightweight resource groups and their resources, see Sun StorEdge Availability Suite 3.2.1 Lightweight Resource Groups.
Verifies that a replication resource of the type GeoCtlAVS is created in the replication resource group of each device group in the protection group. For information about the format of the replication resource group, see Sun StorEdge Availability Suite 3.2.1 Replication Resource Groups.
Verifies that the Nodelist property of the lightweight resource group and replication resource group contains the same entries in identical order to the Nodelist property of the protection group.
If the Enable_volume_set property of a successfully validated device group is set to True, then volume sets defined in the /var/cluster/geo/avs/avsdg-volset.ini file are enabled. Other volume sets for the device group are disabled. If you want to enable the other volume sets, you can add the volume sets to the /var/cluster/geo/avs/avsdg-volset.ini file or set the Enable_volume_set property to False.
When validation is complete, the Sun Cluster Geographic Edition software creates the lightweight resource group, the replication resource group, and the resources for this replication resource group, if nonexistent, and brings them online. If a resource group or resource of the same name already exists, the Sun Cluster Geographic Edition operations might modify their properties. Sun Cluster Geographic Edition software cannot create a new resource group or resource of the same name if one already exists.
The Configuration status is set to OK after successful validation. If validation is not successful, the Configuration status is set to Error.
