Recovering from a disaster by using MetroCluster configurations
In situations such as prolonged power outages or natural disasters, you can use the MetroCluster feature of Data ONTAP to provide a quick failover to another site that contains a nearly real time copy of the data at the disaster site.
Conditions that constitute a disaster
The disaster recovery procedure is an extreme measure that you should use only if the failure disrupts all communication from one MetroCluster site to the other for a prolonged period of time.
Recovering from a disaster
After determining that there is a disaster, you should take steps to recover access to data, fix problems at the disaster site, and re-create the MetroCluster configuration.
