A method and system for recovering a server blade, in a multiple server
blade computer, that is lost during a flash update operation on a service
processor in the server blade. Because of the flash update failure, the
lost server blade is unaware of its location on a management pathway,
which in an exemplary form may be a midplane or a bus, which connects the
server blade and a management module in a server blade chassis. The lost
server blade puts a signal on the management pathway indicating that the
flash failed. The signal is put on a special channel reserved for such
messages. The management module receives the signal, and then determines
which of the multiple server blades are lost due to the flash update
failure.
