An Isilon customer has two 5-node clusters, one for production and one for disaster recovery (DR). The customer's workflows are replicated to the DR cluster through SyncIQ on individual schedules. They have shutdown their production cluster for scheduled maintenance, failed over to the DR cluster, and are currently operating from the DR site. Assume both clusters have identical shares, exports, user authentication, and that the client applications have been stopped and the DNS re- pointed. What is the easiest method to continue operations on production?
