Creating the base service groups for DR configuration
You need to create the base service groups in Cluster Server and link those base service groups and resource types for DR configuration.
You need to create at least the following service groups with their respective resources on Node1 and Node2:
| Service group | Resource |
|---|---|
| SFM_SStore | - SFM_SStore_DG |
| - SFM_SStore_RVG | |
| SFM_Services | - SFM_Services_IP |
| - SFM_Services_NIC | |
| - SFM_Services_Mount | |
| - SFM_Services_RVGPrimary |
Note: For DR configuration, you need to use the service group names and resource names as suggested. Failure to do so may result in configuration failure.
It is recommended to set up the VVR rlinks under Cluster Server control. No naming convention is required for the VVR rlink resources. For more information, refer to the Cluster Server Bundled Agents Reference Guide and Cluster Server Agents for Volume Replicator Configuration Guide depending on the version of the Cluster Server.

For the resources that you need to create on the SFM_SStore service group, refer to the following table:
Resource name Resource type Attributes SFM_SStore_DG Disk group Diskgroup : Disk group that is specified for the failover. Note: You must create a clustered disk group. SFM_SStore_RVG RVG RVG : Replicated volume group (RVG) that is configured for replication of volumes Diskgroup : Disk group that is used for creating RVG. -
For HA-DR configuration, you need to create the resources that are created for HA configuration as well as some additional resources.
For the resources that you need to create apart from the resources already created, refer to the following table:
| Resource name | Resource type | Attributes |
|---|---|---|
| SFM_Services_RVGPrimary | RVG Primary | Contains the RVG resource name that is to be used for replication. |
For more information on configuring resources, refer to the Cluster Server Bundled Agents Reference Guide.
After creating the required service groups and resources, you need to link the base service groups. For selecting the options while linking the service groups, refer to the following table:
| Selection | Option |
|---|---|
| SFM_Services | Parent Group |
| SFM_SStore | Child Group |
| Relationship | Online Local |
| Dependency Type | Hard |
You need to link the resources. For selecting parent and child dependencies, refer to the following table:
| Parent Dependency | Child Dependency |
|---|---|
| SFM_SStore_RVG | SFM_SStore_DG |
| SFM_Services_IP | SFM_Services_NIC |
| SFM_Services_Mount | SFM_Services_RVGPrimary |
| SFM_Services_RVGPrimary | SFM_Services_IP |
After creating the SFM_Services and SFM_SStore service groups on Site A and linking them, repeat the same procedure for site B. On Site B, ensure that the SFM_Services_NIC, SFM_SStore_RVG, and SFM_SStore_DG are online and rest of the resources are offline. Also, you must configure SFM_Services service group as Global on site A and add Site B in the cluster.
