Abstract

A running of an application resource of a first site of at least two sites is stopped from accessing a storage device of the first site. A running of a replication resource is brought to a stop. The replication resource is 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. A replication request is submitted to the automation engine for changing a replication direction to run from the second site to the first site. The application resource is started 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.
