Abstract
Aspects of the present invention include a method, system and computer program product. The method includes a processor operating first and second physical channel identifier (PCHID) devices comprised of a plurality of functional logic components, wherein one or more of the functional logic components are specific to one or more of the first and second PCHIDs and wherein one or more of the functional logic components are in common and not specific to one or more of the first and second PCHIDs; determining that an error condition exists in the first PCHID or the second PCHID; executing a recovery method to remove the error condition from the first PCHID or the second PCHID in which the error condition exists; and executing, by the processor, an initialization method for both of the first and second PCHIDs.
