Method for controlling changes of replication directions in a multi-site disaster recovery environment for high available application

A method for processing a disaster recovery setup using a policy-based automation engine controlling at least two sites of a computing environment, the method comprising:

• stopping a running of an application resource of a first site of the at least two sites from accessing a storage device of the first site, each of the at least two sites comprising a server with an application resource and a storage device for storing data of the application resource;
• bringing to a stop a running of a replication resource, the replication resource configured to control a replication of data between the storage device on the first site on which data from the running application resource on the first site are stored to the storage device on the second site;
• submitting a replication request to the automation engine for changing a replication direction to run from the second site to the first site;
• and
• starting the application resource on the second site only after changing the replication direction to start from the storage device on the second site instead of from the storage device of the first site.
