Patent ID: 8201167

Claim:
A method, in a data processing system, for an on-demand allocation of virtual asynchronous services interface adapters, the method comprising: determining if an operation request requires that a set of virtual I/O service partitions have a required number of virtual asynchronous services interface adapters; responsive to the operation request requiring that the set of virtual I/O service partitions have a required number of virtual asynchronous services interface adapters, determining if the set of virtual I/O service partitions have the required number of virtual asynchronous services interface adapters; responsive to the set of virtual I/O service partitions failing to have the required number of virtual asynchronous services interface adapters, defining a set of new virtual asynchronous services interface adapters in partition management firmware and in the set of virtual I/O service partitions; configuring the set of new virtual asynchronous services interface adapters in the set of virtual I/O service partitions; and issuing the operation to the set of virtual I/O service partitions, wherein the set of virtual I/O service partitions communicate with the partition management firmware via the set of new virtual asynchronous services interface adapters.
