Two PowerMax arrays have been configured for replication using SRDF. During a disaster recovery operation, production has been transferred to the R2 devices at the target site. Which operation begins the transfer of accumulated invalid tracks from the R2s to the R1s while production work continues on the R2s?
In the context of SRDF (Symmetrix Remote Data Facility) during a disaster recovery operation, when production has been transferred to the R2 devices at the target site, the correct operation to begin the transfer of accumulated invalid tracks from the R2s to the R1s while continuing production work on the R2s is the 'Resume' operation. This operation resumes SRDF replication, syncing the differences (invalid tracks) from R2 back to R1 without interrupting ongoing production work on the R2 devices.
failback would stop production work on site R2
Update is the correct answer
