WIL from the primary site is irrelevant after the MirrorView/S secondary images have been promoted. B. WIL is stored on the SP cache and it was lost during the outage. C. WIL was lost on the production data center during the outage and a full re-synchronization of all the LUNs was required. D. WIL was never transferred after the outage. Answer: A 3.
