Selective generation of an asynchronous notification for a partition management operation in a logically-partitioned computer

A program product, comprising:

• a recordable medium;
• and
• program code stored on the recordable medium and configured upon execution to change the state of a resource in a logically partitioned computer that includes a plurality of partitions managed by a partition manager by:
• 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:
• returning a synchronous notification to the first partition in response to receiving the request, the synchronous notification indicating one of an invalid request, in progress, successful completion, and unsuccessful completion status for the state change operation;
• and
• returning an asynchronous notification to the first partition upon completion of the state change operation only if the state change operation was still in progress when the synchronous notification was generated and the correlation token indicates that an asynchronous notification should be generated, the asynchronous notification identifying the correlation token to correlate the asynchronous notification with the request;
• and
• 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.
