Summary:A method of and apparatus for creating a data structure or map describing the I/O configuration and of verifying and resolving errors in configuration data in a system in which processors (110,120) are coupled to one another or to device control units (150,160) either directly or through a dynamic switch (130,140) by way of links (105,107) attached to link adapters (151,153) of respective end units (130,150). Each pair of unit link adapters (151,133) coupled to the respective ends of a link (105) exchanges information identifying the unit (150) and the adapter on that unit (151). A physical configuration map indicating the actual physical system configuration is constructed from such "nearest neighbour" information. This physical configuration map is compared with a logical configuration map indicating the user-defined logical system configuration to determine the existence of any discrepancies therebetween, and one map is conformed to the other as appropriate.
