摘要： A technique for performing a system dump in a data processing system that implements active memory sharing includes assigning, via a hypervisor, a logical partition to a portion of a shared memory. One or more virtual block storage devices are also assigned by the hypervisor to the logical partition to facilitate active memory sharing of the shared memory. When a hypervisor-aided firmware-assisted system dump is indicated and a failure of the logical partition is detected, firmware initiates a system dump of information from the assigned portion of the shared memory to the one or more virtual block storage devices. An operating system of the logical partition is rebooted when enough of the assigned portion of the shared memory is freed to facilitate a reboot of the operating system and the hypervisor-aided firmware-assisted system dump is indicated.

摘要： Systems, methods and media for sharing an application among multiple server systems are disclosed. In one embodiment, the application is stored on a fast disk paging device. The paging device is in communication with each of a plurality of servers so that each server may be given access to the application. Virtual real memory (VRM) is allocated to a first virtual client of the first server. A portion of this VRM is allocated to the application. The application is executed by a virtual client of a first server. During execution a condition may occur that requires taking the first server off line. In that event, VRM is allocated to a second virtual client of a second server. A portion of this VRM is allocated to the application. The application is then executed by the second virtual client of the second server.

摘要： A method, system, and computer program product utilizes cluster-awareness to effectively maintain and update Persistent Reserve (PR) state data and provide nodes with notification of changes to PR state data within a Virtual Input/Output (I/O) Server (VIOS) cluster. A Persistent Reserve (PR) utility identifies a database that is accessible to other VIOSes in the cluster, in which database information about the current state of the Persistent Reservation is maintained. The PR utility checks the current Persistent Reserve state in the database to verify whether an initiator of a PR command is allowed to perform the command. If the initiator is allowed to perform the command, the PR utility modifies/updates the Persistent Reserve state in the database to reflect the received Persistent Reserve command. The PR utility updates the initiator's local copy of the modified PR state data and sends a corresponding notification message to other VIOSes in the cluster.

摘要： In a data processing system having a plurality of virtualized operating system (OS) partitions, a first cluster-aware virtual input/output server (VIOS) is provided within an OS partition by execution of a cluster-aware (CA) OS on a virtual processor resource of the first VIOS. The CA OS establishes the VIOS as a cluster-aware VIOS by registering the first VIOS with a VIOS cluster comprising a second VIOS. Registering the first VIOS to the VIOS cluster enables the first VIOS to receive VIOS cluster configuration data and status data, which provides the first VIOS with information about the other VIOSes within the VIOS cluster. The first VIOS is thus able to communicate with other VIOSes within the VIOS cluster and share I/O resources with the other VIOSes within the VIOS cluster. Relevant cluster information is stored within a local storage of the first VIOS.
