What happens if the Receive Delta Set on one of the target arrays is incomplete?

SRDF/A MSC has been configured between two sites. There are two PowerMax arrays at the source site and two PowerMax arrays at the target site. An SRDF/A MSC trip event has occurred.

What happens if the Receive Delta Set on one of the target arrays is incomplete?
A . Transmit Delta set is discarded
B . Session is marked as No Cleanup required
C . Receive Delta Set data is discarded
D . Session is marked as Cleanup required

Answer: D

Explanation:

The correct answer is D. When an SRDF/A MSC trip event occurs, the Receive Delta Set on the target arrays is checked for completeness. If the Receive Delta Set is incomplete on any of the target arrays, the session is marked as Cleanup required. This means that the data on the target arrays is not consistent and needs to be cleaned up before resuming SRDF/A replication. The symstar cleanup command can be used to discard the incomplete Receive Delta Set data and resume SRDF/A replication from the last consistent point1
