In the SRDF configuration shown, the R1 volumes are write-enabled, the R2 volumes are write-disabled and the SRDF link is ready. What happens if the Host on site A fails?

A.
The Symmetrix will detect the failure and automatically write-enable the R2 Volumes. The production work could then be restarted on the host on site B.

B.
An SRDF failover operation must be executed for the SRDF pairs. The production work could then be restarted on the host on site B.

C.
The production work must be suspended until the host on site A can be restored.

D.
The host on site B can access the R1 Volumes through the SRDF links and continue the production work with the R1 Volumes.
