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.

The method includes maintaining a plurality of evaluation strategies, wherein the evaluation strategies associate a plurality of rules with forms of changes to the plurality of information technology resources. Responsive to detecting a command to change a first property of the set of properties of a first information technology resource of the plurality of information technology resources, the method determines that a first of the evaluation strategies associates at least one of the plurality of rules with a form of the change to the first property of the first information technology resource. Also, responsive to detecting the command, the method evaluates the at least one of the plurality of rules and performs the operation of the at least one rule.

An embodiment of the invention is directed to a method associated with a node comprising a hypervisor and guest VMs, each guest VM being managed by the hypervisor and disposed to run applications, the node being joined with other nodes to form an HA cluster. The method includes establishing an internal bidirectional communication channel between each guest VM and the hypervisor, and further includes sending commands and responses thereto through the channel, wherein respective commands manage a specified application running on the given guest VM. The messages are selectively monitored, to detect a failure condition associated with the specified application running on the given guest VM. Responsive to detecting a failure condition, action is taken to correct the failure condition, wherein the action includes sending at least one command through the internal channel from the hypervisor to the given guest VM.

A method of selecting active members of resource groups is disclosed. The method includes assigning a first label from a predetermined static label set to a first member of a first resource group. The method includes assigning a second label from the predetermined static label set to a second member of the first resource group. The method further includes assigning the first label to a third member of a second resource group. The method includes assigning the second label to a fourth member of the second resource group. The method also includes selecting an active label from the predetermined static label set in response to a command received at a computing system. Upon selection of the active label from the predetermined static label set, computing resources identified by members associated with the active label are automatically placed online and computing resources identified by members associated with a label other than the active label are automatically placed offline.

Embodiments provide a method of dynamically setting the automation behavior of resources via switching between an active mode and a passive mode. One embodiment is a method that includes placing a first computing resource into a first desired state and an active behavioral mode and placing a second computing resource having a relationship to the first resource into the first desired state when a first request for the first resource that specifies the first desired state is received. The method also includes placing the first computing resource into a standby state and a passive behavioral mode and not placing the second computing resource into the first desired state.

Dynamically setting the automation behavior of resources

The present invention provides a system and method for automatically managing IT-resources in a heterogeneous environment on each level of resource abstraction and resource hierarchy by using the concept of the resource-reference object. The resource-reference object represents the link to a referenced resource on a lower level in the hierarchy and may include a priority value assigned by the respective level of hierarchy as well as all information to build a remote request to that referenced resource which may be a single resource or a resource group. Concurrently each resource-reference object itself is accessible from the higher level of hierarchy as an own resource by additional providing a name and a desired state which can differ from desired state of the referenced resource as well as making it externally visible. Resource-reference objects can be grouped to resource groups on the higher level of hierarchy, wherein those resource groups are addressable as own resource-reference object from the next higher level of hierarchy. By using the inventive concept of the resource-reference object conflicts between different levels of hierarchies in the system management are resolved by a conflict resolution method using the priority assigned to the resource reference object by the respective level of hierarchy.
