    We are working with a customer’s MirrorView/A + SRM + VNX deployment. To simplify operations, we want to avoid a full synchronization after failover. However, every time we do a failover the entire data set at the protected site is copied back to the original production site.

    We even did a test without SRM and verified that after going to synchronized state we can promote the consistency groups at the protected site and no full sync is needed. But with the SRM/SRA we cannot get the solution to do an incremental re-sync (not a full sync). It almost looks like the SRA with MV/A it is not possible to avoid a full sync.

    Can anyone tell me if SRM with MV/A is capable of a failover without a full sync? If it is, what do we need to do to make this happen?
