A database server has its logs stored on a volume on the log source Symmetrix V-Max array and its data stored on a volume on the data source Symmetrix V-Max array. Both source Symmetrix V- Max frames replicate data to the target Symmetrix) V-Max at the disaster recovery site.

Two device groups have been defined:

One group for the data volume on the Symmetrix containing the data LUNs

One group for the log volume on the Symmetrix containing the log LUNs.

Whathappens if the SRDF links between the Symmetrix containing the data LUNs and the target Symmetrix were to fail?

A.
theR2 data in the database remains consistent because enginuity Consistency Assist (RDF- ECA) technology would ensure data consistency.

B.
The data in the database becomes inconsistent at the Remote Site.

C.
theR2 volumes in the Symmetrix V-Max containing thelog LUNswould become write-disabled to the database server.

D.
anSRDF failover would be initiated on all volumes and processing will automatically be switched over to disaster recovery site.
