1. A method of detecting primary site failure and automating failover to a destination site on a replication data facility, comprising:
generating a replication data facility configuration file by the destination site, the replication configuration file containing information about the replication data facility, the replication data facility including the primary site, the destination site, and a plurality of replication data facility links facilitating transmission of data from the primary site and destination site, the primary site including a cluster of nodes, each node implementing one or more Network Attached Storage (NAS) servers associated with the replication data facility;
using the information about the replication data facility from the replication data configuration file to monitor a plurality of health indicators of the replication data facility, by a health monitor implemented as part of a cluster management stack on the destination site, to detect the primary site failure on the replication data facility; and
in response to detecting the primary site failure on the replication data facility, using the replication data facility configuration file, by a failover manager on the destination site, to implement automated parallel failover of each of the NAS servers associated with the replication data facility to the destination site.
