摘要： A system and computer program product utilizes cluster-awareness to effectively support a live partition mobility (LPM) event and provide recovery from node failure within a Virtual Input/Output (I/O) Server (VIOS) cluster. An LPM utility creates a monitoring thread on a first VIOS on initiation of a corresponding LPM event. The monitoring thread tracks a status of an LPM and records status information in the mobility table of a database. The LPM utility creates other monitoring threads on other VIOSes running on the (same) source server. If the first VIOS sustains one of multiple failures, the LPM utility provides notification to other functioning nodes/VIOSes. The LPM utility enables a functioning monitoring thread to update the LPM status. In particular, a last monitoring thread may perform cleanup/update operations within the database based on an indication that there are nodes on the first server that are in failed state.

摘要： A first virtual I/O server (VIOS) provides a cluster aware (CA) operating system (OS) executing on a processor resource of the first VIOS to register the first VIOS within a VIOS cluster. The first VIOS comprises a first field/failure data capture (FFDC) module that executes within the first VIOS and performs the functions of: receiving from an event listener a signal indicating that an FFFDC event/condition has been detected by the first VIOS; and automatically transmitting FFDC data to the shared storage repository for storage of the FFDC data within the shared storage repository. The FFDC module further performs the functions of: transmitting to one or more second VIOSes within the VIOS cluster, one or more messages to inform the one or more second VIOSes of an occurrence of the FFDC event/condition that was detected by the first VIOS.

摘要： A method, data processing system, and computer program product autonomously migrate clients serviced by a first VIOS to other VIOSes in the event of a VIOS cluster “split-brain” scenario generating a primary sub-cluster and a secondary sub-cluster, where the first VIOS is in the secondary sub-cluster. The VIOSes in the cluster continually exchange keep-alive information to provide each VIOS with an up-to-date status of other VIOSes within the cluster and to notify the VIOSes when one or more nodes loose connection to or are no longer communicating with other nodes within the cluster, as occurs with a cluster split-brain event/condition. When this event is detected, a first sub-cluster assumes a primary sub-cluster role and one or more clients served by one or more VIOSes within the secondary sub-cluster are autonomously migrated to other VIOSes in the primary sub-cluster, thus minimizing downtime for clients previously served by the unavailable/uncommunicative VIOSes.

摘要： In a data processing system having a plurality of virtual input/output servers (VIOSes) configured within a VIOS cluster, a method, data processing system and computer program product provide for autonomous election of a primary node within a virtual input/output server (VIOS) cluster. A first VIOS performs the functions of: detecting that a primary node is required for the VIOS cluster; and autonomously initiating an election process to elect a next primary node from among the VIOSes within the VIOS cluster. When the first VIOS meets the pre-established requirements for becoming a primary node, the first VIOS obtains a lock on a primary node ID field within a VIOS database (DB) and then initiates a primary node commit process to assign the first VIOS as the primary node. The first VIOS issues a notification to the VIOS cluster to notify the other VIOSes that a primary node has been elected.

摘要： A method, system, and computer program product provides effective management and deployment of image files within a Virtual Input/Output (I/O) Server (VIOS) cluster. An Image Management (IM) utility utilizes a discovery process to establish connections with objects in order to manage these objects. Following discovery of an ICP client, the IM utility enables creation of a virtual server partition and initiates the importing of a captured image to a VIOS cluster Storage Pool (SP). The IM utility creates logical units (LUs) within the Image Management Fileset (IMF) for each file within the captured image. The IM utility maps the LUs to the VIOS Cluster SP using unique image file handles. The IM utility configures the new storage that comprises the created LUs. The IM utility copies image files to the appropriate storage device/LU. When import/copy of the image is completed, the IM utility activates the virtual server partition.

摘要： A method, system, and computer program product provide a shared virtual memory space via a cluster-aware virtual input/output (I/O) server (VIOS). The VIOS receives a paging file request from a first LPAR and thin-provisions a logical unit (LU) within the virtual memory space as a shared paging file of the same storage amount as the minimum required capacity. The VIOS also autonomously maintains a logical redundancy LU (redundant LU) as a real-time copy of the provisioned/allocated LU, where the redundant LU is a dynamic copy of the allocated LU that is autonomously updated responsive to any changes within the allocated LU. Responsive to a second VIOS attempting to read a LU currently utilized by a first VIOS, the read request is autonomously redirected to the logical redundancy LU. The redundant LU can be utilized to facilitate migration of a client LPAR to a different computing electronic complex (CEC).
