A method and system for automatically performing one or more operations on multiple computer systems within a cluster are disclosed. In accordance with the present invention, a begin operations command construct is defined within an input file. In addition, an input command indicating one or more operations to be performed on at least two computer systems within the cluster and an end operations command construct are defined. In response to a selected input, one or more operations indicated by the input command are automatically performed on at least two computer systems. In accordance with one embodiment, the begin operations command construct indicates selected computer systems within the cluster on which the one or more operations are to be performed and whether the operations are to be performed on the selected computer systems serially or in parallel.

A method and system for dynamically reconfiguring a cluster of computer systems are disclosed. In accordance with the present invention, a first configuration file is provided at a plurality of computer systems within a cluster that specifies a current configuration of the cluster. A second configuration file is created at each of the plurality of computer systems that specifies a modified configuration of the cluster. The modified configuration is then verified. In response to the verification, the cluster is operated utilizing the modified configuration. In accordance with one embodiment, the dynamic reconfiguration of the cluster can include a reconfiguration of the cluster topology or resources.
