Abstract
A method, system and computer program product for remotely debugging a malfunctioning node controller of a node in a distributed node network through a functioning node controller of the same node. The method comprises establishing a serial link between the malfunctioning node controller and a functioning node controller and configuring the functioning node controller as a virtual console by the remotely-located central data processing system (DPS). The method further includes receiving, via an internal Fru Support Interface (FSI) link, serial data from the malfunctioning node controller through the virtual console, and debugging, by the DPS, a failure condition of the malfunctioning node controller, in response to receipt of the serial data through the virtual console.
