Patent ID: 7171590

Claim:
A multi-processor system comprising: a plurality of node groups each including a plurality of nodes and a service processor for managing said plurality of nodes; a service processor manager for managing said service processors of said plurality of node groups; a network for interconnecting said plurality of nodes of said plurality of node groups, and a partition including a selected number of nodes selected from said plurality of nodes of said plurality of node groups, wherein: a failed node among said selected number of nodes transmits failure information including occurrence of a failure to a corresponding service processor, which prepares first status information of said failed node based on error log information of said failed node and transmits said first status information to said service processor manager; said failed node transmits failure notification data including said failure information to other nodes of said selected number of nodes; said other nodes transmit said failure information to respective said service processors, which prepare second status information based on error log information of said other nodes and transmit said second status information to said service processor manager; and said service processor manager identifies a location of said failed node based on said first and second status information to indicate said service processors in said partition to recover from said failure.
