Abstract
The present invention determines an incorrect packet from a faulty partition quickly and reliably and prevents the packet from flowing into normal partitions through simple control actions. The multi-partition computer system is a multi-partitioned computer system in which a plurality of nodes are logically divided into a plurality of partition, and each node contained in the partitions includes a packet identification unit which, upon receiving a packet, compares the partition identification information uniquely assigned to own partition against the partition identification information contained in the receive packet, and if these pieces of information do not match each other, judges and discards the receive packet as an incorrect packet.
Claims22
A multi-partitioned computer system in which a plurality of nodes are logically divided into a plurality of partitions, wherein a node contained in one of said partitions including
- a packet identification unit which, upon receiving a packet, compares the partition identification information uniquely assigned to own partition against the partition identification information contained in the receive packet, and if these pieces of information do not match each other, judges and discards said receive packet as an incorrect packet.
A node in a multi-partitioned computer system in which a plurality of nodes are logically divided into a plurality of partitions, comprising:
- having a packet identification unit which, upon receiving a packet, compares the partition identification information uniquely assigned to own partition against the partition identification information contained in the receive packet, and if these pieces of information do not match each other, judges and discards said receive packet as an incorrect packet.
A failure handling method for a multi-partitioned computer system in which a plurality of nodes are logically divided into a plurality of partitions, comprising:
- a node contained in one of said partitions performing steps of:
- upon receiving a packet, comparing the partition identification information uniquely assigned to own partition against the partition identification information contained in the receive packet;
- and
- if these pieces of information do not match each other, judging and discarding said receive packet as an incorrect packet.
A computer readable medium storing a failure handling program executed on said node in a multi-partitioned computer system in which a plurality of nodes are logically divided into a plurality of partitions, wherein said failure handling program causes a node contained in one of said partitions, upon receiving a packet, to execute a processing of comparing the partition identification information uniquely assigned to own partition against the partition identification information contained in the receive packet, and if these pieces of information do not match each other, judging and discarding said receive packet as an incorrect packet.
