ABSTRACT:
A method and computer program product for error monitoring partitions in a computer system. Provided to each partition is a partition status indicator (PSI) denoting a RUNNING or FAIL status of the partition, and an error log area (ELA) for storing partition error entries. The ELA includes a partition identifier, an entry status indicator (ESI) indicating READ/UNREAD status for the error entry, and an error identifier. An error procedure performed for each first partition whose partition status indicator indicates the FAIL status includes: copying each error entry in the ELA of the first partition whose ESI indicates the UNREAD status into the ELA of a second (running) partition; setting the ESI to the READ status for each copied error entry in the ELA of the first partition; and having the ESI set to the UNREAD status for each copied error entry in the ELA of the second partition.
