Question
How is the Host I/O served after running the Non-Disruptive Migration cutover command?
A. Host I/O sent to the new storage system is replicated to the old storage system using SRDF Pass-Through
B. Host I/O is sent only to the old storage system and replicated to the new storage system using SRDF/S
C. Host I/O is sent only to the new storage system and replicated to the old storage system using SRDF/S
D. Host I/O sent to the old storage system is replicated to the new storage system using SRDF Pass-Through
Answer
C. Host I/O is sent only to the new storage system and replicated to the old storage system using SRDF/S
Explanation
After running the Non-Disruptive Migration cutover command, host I/O is sent exclusively to the new storage system. The new storage system then replicates the I/O to the old storage system using SRDF/S (Symmetrix Remote Data Facility/Synchronous) replication. This ensures that the old storage system remains in sync with the new storage system, providing a consistent and up-to-date copy of the data. The old storage system no longer directly receives host I/O, as all I/O is now directed to the new storage system.
