The Sun Cluster Geographic Edition software internally changes some properties for the SUNWscgrepsrdf resource. Therefore, you must not edit these properties manually.
For EMC Symmetrix Remote Data Facility, do not edit the following properties:
DG_or_CG – Defines the EMC Symmetrix Remote Data Facility device group that contains the volumes that are being replicated.
R1_SID – Defines the local data replication role.
R2_SID – Defines the local data replication role.
