ABSTRACT:
Methods, systems, and articles of manufacture for replacement of a failing processor of a multi-processor system running at least one operating system are provided. In contrast to the prior art, the replacement may be performed by system firmware without intervention by the operating system (i.e., the replacement may be transparent to the operating system). For some embodiments, the multi-processor system may be logically partitioned and the methods may be utilized to replace one or more shared or dedicated processors assigned to a logical partition, transparent to an operating system running on the partition.
