Abstract
A method and an information handling system (IHS) perform server boot failure recovery by disabling failed devices and/or failed functions within functional devices. According to one aspect, a processor-executed fault isolation module (FIM) initiates calls to detected devices during a binding phase. The FIM identifies devices corresponding to successfully completed calls as operational devices, and identifies devices corresponding to failed calls as failed devices. Following completion of the binding phase, the FIM initiates calls, via a pre-boot application, to individual protocol functions of each operational device identified during the binding phase. If a first protocol call to a first operational device is successfully completed, the FIM identifies a protocol function(s) corresponding to the first protocol call as an operational function(s). If a second protocol call fails, the FIM identifies a corresponding protocol function(s) as a failed function(s) and isolates failed functions from operational functions for the first operational device.
