Abstract: A method and system for providing a shared data resource coordinator within a storage virtualizing data processing system is disclosed. According to one embodiment of the present invention, a first node of a plurality of nodes is configured to process requests to access a shared data resource on behalf of the plurality of nodes, where the plurality of nodes includes a logical volume configuration server configured to present a logical volume to one or more logical volume configuration clients. A second node is then selected from the plurality of nodes and configured to process requests to access the shared data resource on behalf of the plurality of nodes.

Abstract: A method and process for providing a memory dump of less than the entire contents of memory is provided. The memory locations to be dumped are selected on the basis of recency of use, so that there is a high probability that portions of memory needed for analysis or evaluation of the computer system will be included in the selective dump. Preferably, the select ion is made on the basis of information or hardware which is already provided in the computer system. In one preferred embodiment, memory to be dumped is selected on the basis of memory locations encoded for by a translation lookaside buffer.
