About the agent for EMC SRDF/Star
The Cluster Server for EMC SRDF/Star provides failover support and recovery in environments that use the SRDF/Star solution to protect their data. SRDF/Star employs a three-point triangular topology to provide data protection and failure recovery among three geographically separated sites.
The SRDF/Star solution mirrors production data on a Symmetrix array at a local site, called the workload site, to Symmetrix arrays at two remote sites. The SRDF/Star technology replicates data synchronously to one remote site, called the sync target, and asynchronously to the other remote site, called the async target. The sync target is in the same region as the workload site; the async target is at a distant location.
SRDF/Star protects against a workload site failure by performing incremental recovery and data replication among the three sites. Depending upon the failure scenario, either of the remote sites can become the new production workload site.
The agent monitors and manages data recovery and replication for a specific composite group that you configure as part of the SRDF/Star configuration.
Before bringing the agent online, ensure that:
SRDF/Star is configured such that STAR can be enabled from the sites.
The Workload site can be failed over from one site to the other.
