Replication link failure
In this scenario, either or both of the synchronous and asynchronous replication links are lost. When any replication (RDF) link is lost, STAR goes into the tripped state.
At this point, the application continues to run on the workload site, but simultaneous synchronous and asynchronous replication is not available. Star is not in the PROTECTED state.
If desired, you can use the agent to switch the application to the sync or async target sites while the RDF links are unavailable. To do this, set the ForceOnline and TripTakeover attributes to 1.
Note:
Veritas recommends that you set these attributes back to their default values after performing a switch of this type.
After both RDF links are available, Star remains in the TRIPPED state because the agent does not monitor the RDF link status. You can regain Star protection by re-enabling it outside of VCS control.
