Validations Made by the Data Replication Subsystem

When the EMC Symmetrix Remote Data Facility device group is added to a protection group, the data replication layer makes the following validations.

• The specified device group name exists in the EMC Symmetrix Remote Data Facility configuration.

• The replication role matches the EMC Symmetrix Remote Data Facility protection group role.

• The EMC Symmetrix source, R1SID, and the EMC Symmetrix target, R2SID, can be reached.

When an EMC Symmetrix Remote Data Facility device group is added to a protection group, a Sun Cluster data replication resource is automatically created by this command. This resource monitors data replication state. The name of the resource is sc_ggeo_dr-SRDFprotectiongroupname-devicegroupname. This resource is placed in the corresponding Sun Cluster resource group, which is named sc_geo_dr-SRDFprotectiongroupname.

Do not change, remove, or bring offline these resources or resource groups. Use only Sun Cluster Geographic Edition commands to administer replication resource groups and resources that are internal entities managed by Sun Cluster Geographic Edition software. Altering the configuration or state of these entities directly with Sun Cluster commands could result in unrecoverable failure.
