Abstract:
A method, system and computer program product are provided for implementing shared adapter configuration updates concurrent with maintenance actions for a Single Root Input/Output Virtualization (SRIOV) adapter in a computer system. A configuration of the adapter is decoupled from the state of the adapter during a recovery period. When a configuration request is received, the configuration request is validated. Responsive to a valid configuration request, the saved configuration state of the adapter is updated. Once the adapter completes recovery, the adapter is restored to the new configuration instead of the configuration prior to failure.
