Method and system for log repair action handling on a logically partitioned multiprocessing system

摘要

A method for handling a log repair action in a logically partitioned (LPAR) multiprocessing system is disclosed. The LPAR multiprocessing system includes a plurality of partitions. The method and system comprise recording the log repair action on one of the plurality of partitions. The method and system further include sending the recording of the log repair action to a single log repair action source, the recording including the log repair action and the partition identifier of the one of the plurality of partitions. The method and system further includes sending the log repair action to each of the other of the plurality of partitions from the single service. Accordingly, a system and method in accordance with the present invention solves the problem of having to perform the same action in multiple partitions by using a notification scheme with a single focal point of control. When the focal point determines that the action performed is common to other partitions, that action is broadcast by the focal point to the other partitions and thus eliminates the need for visiting each partition to repeat the action. Each receiving partition uses the broadcast information to update its log repair action record. Accordingly shortened repair scenarios and less interruptions to actively working partitions is provided, thus providing the customer with increased system availability which should result in higher customer satisfaction.
