What is the result of one or more source (R1) devices in an SRDF/S consistency group cannot
propagate data to their corresponding target (R2) devices?

A.
RDF daemon suspends the data propagation from the affected R1 devices while maintaining
consistency among the remaining devices.

B.
PowerPath suspends data propagation to the R1 devices in the consistency group (trip the congroup)

C.
EMC software trips the con-group, thereby suspending data propagation from all R1 devices in
the consistency group

D.
Target (R2) devices will be Read/Write enabled at the R2 site.
