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.

摘要： A method provides input/output (I/O) redundancy within a data processing system having (a) a client logical partition (LPAR) that generates and consumes I/O requests, (b) a plurality of virtual input/output servers (VIOS) that are communicatively inter-connected with each other to form a VIOS cluster and which include virtual I/O adapters for connecting to a fabric that provides access to a block storage. In one embodiment, a first VIOS receives an I/O request from the client LPAR. The first VIOS detects that a problem exists with a fabric connection to the block storage, and the first VIOS responds to the detected connection problem by autonomously propagating the I/O request to a second VIOS to which the first VIOS is connected. Forwarding of the I/O request to the block storage is subsequently completed by the second VIOS.

摘要： In a data processing system including a virtual I/O server (VIOS) cluster and multiple logical partitions (LPARs), at least one VIOS of the VIOS cluster performs functions of: receiving first registration information from one or more entities within the VIOS cluster; registering, based on the first registration information, a handler associated with a first message type; responsive to receiving second registration information, registering, based on the second registration information, a listener associated with a second message type; receiving a first message associated with a first alert event of the cluster; determining, based on the first message, that the handler is associated with the first message type; and calling the handler. In one embodiment, the handler is associated with a pointer to a subroutine, and registering the handler includes storing the pointer in a data structure that associates the handler with the first message type.

摘要： Systems, methods and media for providing to a plurality of WPARs private access to physical storage connected to a server through a VIOS are disclosed. In one embodiment, a server is logically partitioned to form a working partition comprising a WPAR manager and individual WPARs. Each WPAR is assigned to a different virtual port. The virtual ports are created by using NPIV protocol between the WPAR and VIOS. Thereby, each WPAR has private access to the physical storage connected to the VIOS.
