摘要：
Techniques are disclosed to perform an operation to facilitate concurrent repair of PCIe switch units in processing environments such as a tightly coupled, multi-switch, multi-adapter, multi-host distributed system. The operation, for an identified switch unit to be repaired, reconfigures all switch unit hardware in the switch fabric by removing all upstream to downstream connections utilizing the identified switch unit. Connections to hosts via the upstream ports are also removed by the operation. Once the switch unit is powered back on, the operation reconfigures all switch unit hardware in the switch fabric by adding all upstream to downstream connections utilizing the identified switch unit. The operation further restores connections to hosts via the upstream ports.
