Multiple RDF groups from different Symmetrix arrays have been grouped together to enable MultiSession Consistency. How does cycle switching occur in this configuration?
A.
Cycle switches are controlled by the RDF daemon
B.
Cycle switches always occur simultaneously on all Symmetrix arrays after 30 seconds
C.
Cycle switches are controlled by the master Symmetrix
D.
Cycle switches always occur independently on each Symmetrix after 30 seconds
Explanation:
In MSC, the Transmit cycles on the R1 side of all participating sessions must be empty, and also
all the corresponding Apply cycles on the R2 side. The switch is coordinated and controlled by
the RDF Daemon.
