ABSTRACT:
A method and computer program product for error monitoring partitions in a computer system. A global supervisor mapping (GSM) associates each supervised partition with a supervisor partition that monitors the supervised partition. A partition status buffer (PSB) denotes a status (GOOD, BAD, NOCARE) of the partition. The BAD status denotes that the partition has encountered at least one error that is currently unrepaired. The supervisor partition determines its supervised partition from the GSM and ascertains the status of its supervised partition from the PSB. If the status of the supervised partition is BAD then a recovery procedure is performed by the supervisor partition. The recovery procedure: obtains a grant of access to physical and logical resources of the supervised partition which contains error data of the supervised partition; gathers the error data; and sets the status of the supervised partition to the NOCARE status.
