Disaster Recovery RHEV 3.5

Hello Guys

In my office I have a lab with a environment of RHEV 3.5 and I need to know if is possible set an environment of Disaster Recovery in RHEV.

My environment is the following

Site Primary:

1 Storage Equallogic
1 RHEV-M 6.5
2 RHEV 3.5

Site Secondary
1 Storage Equallogic
1 RHEV-M 6.5
2 RHEV 3.5

In my Site Primary I have 3 VM of testing and I need replicate to secondary site in case of failure of the primary site. I search information and I found that you can export from a Datacenter Storage Domain to another (Admin Guide) but if my Site Primary is fully down I not have options to export data to the site secondary.

In my Equallogic is enable the LUN replication from primary site to secondary site. I need to know if there is another procedure who by example a script to replicate the VM to secondary site.

Thanks for your help.

Regards

Sebastian
