Abstract:
A method, system and computer program product are provided for implementing distributed debug data collection and analysis for a hardware I/O adapter, such as, a Single Root Input/Output Virtualization (SRIOV) adapter in a virtualized system. A predetermined event triggers a base error collection sequence. Adapter driver data is collected and virtual function (VF) device drivers are locked out responsive to triggering the base error collection sequence. Adapter debug data is collected and the adapter is reinitialized including an indication to VF drivers if VF error data is to be collected. The virtual function (VF) device drivers are unlocked allowing the VF device drivers to commence recovery of a respective virtual function (VF).
