We did not complete it then and hopefully by same time this year Aug. we will have it. This is a very complicated feature and we will not release until it is sufficiently stable. So currently in your case solution you will need to set up 1 Source server and 1 Destination server for failover procedures, this is done manually (currently) and we do not have a script to run from the outside. So if Source fails then you instruct Destination to be Source and enable the Target (See manual for these steps) - then instruct initiators to use the new Source IP address. If old Source comes back on line set it to either Destination (See manual for deeper explanation) or Set New Source back to Destination and failed Source as Source then reset the Metadata - clearing of metadata is required when you want to start the replication process from the beginning.
