ABSTRACT:
An apparatus, clustered computer system, program product and method assist in the distribution of configuration data such as VPD for a switchable resource to multiple nodes within a clustered computer system. Program code operating as a resource manager is used to enroll a node to receive updates to a switchable resource in the clustered computer system, and, in response to an update to the switchable resource, to notify each enrolled node of the update. Moreover, configuration data is communicated along with the notification to each enrolled node, such that any data required to initiate acquisition of functional ownership of a switchable resource by any such node will be locally available to such node.
