NO.8 Refer to the exhibit.
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 array
frames replicate data to the target Symmetrix V-Max array at the Remote site. There are two device
groups that 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
What happens if the SRDF inks between the Symmetrix contain the data LUNs and the target Symmetrix
were to fail?
A. The R2 data in the database remains consistent because Enginuity Consistency Assist (RDFECAJ
technology would ensure data consistency).
B. The data in the database becomes inconsistent at the Remote site.
C. An SRDF failover would be initiated on all volumes and processing will automatically be switched over
to the Remote site
D. The R2 volumes in the Symmetrix V-Max containing the log LUNs would become write-disabled to the
database server
