Support for EMC Symmetrix Remote Data Facility Configurations

Geographic Edition software currently supports the following EMC Symmetrix Remote Data Facility (SRDF) configurations:

• Static SRDF device group

• Dynamic SRDF device group

Oracle Solaris Cluster Geographic Edition 3.3 5/11 software supports these configurations in Synchronous and Asynchronous modes for data replication in disaster-recovery environments. Synchronous mode is supported for takeover and switchover operations. Asynchronous mode is supported for takeover operations, and a workaround permits switchover in asynchronous mode as well. For details, see Switchover Cannot Be Performed with Asynchronous SRDF (6389092).

---

Caution - EMC SRDF Adaptive mode is not supported for use with clustered data services. It does not guarantee data consistency in normal operations. The domino option, which can be set on EMC SRDF device pairs, suspends writes to the primary site if writes to the secondary site fail. Any failure of secondary storage or of the communication link between the Geographic Edition partnered clusters might cause the complete loss of application data services. This is not a highly available configuration, and you should not configure the domino option on devices that will be used by clustered data services.

Oracle 9i

Cluster configurations that run Oracle 9i software are not supported by Oracle Solaris Cluster Geographic Edition 3.3 5/11 software.
