Abstract:
1. A method of changing the state of a resource resident in a logically-partitioned computer of the type including a plurality of partitions managed by a partition manager, the method comprising: in a first partition among the plurality of partitions, generating a request to perform a state change operation for a resource resident in the logically-partitioned computer, the request including a correlation token indicating whether an asynchronous notification should be generated upon completion of the state change operation for the resource; attempting to perform the state change operation in the partition manager in response to the request, including: in the first partition, if the correlation token indicates that an asynchronous notification should not be generated, periodically polling the partition manager by generating additional requests to perform the state change operation until a synchronous notification returned in response thereto does not indicate an in progress status for the state change operation.
