Abstract:
A method, system and computer program product are provided for detecting state and sparing of optical Peripheral Component Interconnect Express (PCI-Express or PCIE) cable channels attached to an IO drawer. System firmware is provided for implementing health check functions and state detection and sparing functions. One or more optical cables are connected between a host bridge and an PCIE enclosure, each optical cable includes one or more spare optical channels. An identified failed optical channel is rerouted to the spare optical channel.
