摘要： Mechanisms are provided for an I/O virtualization management partition (IMP) to control the shared functionality of an I/O virtualization (IOV) enabled I/O adapter (IDA) through a physical function (PF) of the IOA while the virtual functions (VFs) are assigned to client partitions for normal I/O operations directly. A hypervisor provides device-independent facilities to the code running in the IMP and client partitions. The IMP may include device specific code without the hypervisor needing to sacrifice its size, robustness, and upgradeability. The hypervisor provides the virtual intermediary functionally for the sharing and control of the IOA's control functions.

摘要： A “LUN Table” enables Logical Unit Number (LUN) mapping/masking within an IOV adapter included in a Serial Attached Small Computer System Interface (“SAS” or “Serial Attached SCSI”). A plurality of System Images (“SI”) share block storage through the SAS. The IOV adapter includes one or more Virtual Functions (VF), a Physical Function (PF), and a LUN Table within the PF. The VF allows each SI to communicate I/0 requests with a storage device through the PF. The LUN Table maps the I/0 requests to unique locations within the storage device. Each SI is isolated from all other SIs. Interference between each SI is avoided. A VIOS or a LUN mapping/masking SAN are not required. I/0 latency, processor overhead and storage cost are improved over prior LUN mapping/masking solutions.

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.
摘要翻译：一个方法，数据处理系统和计算机程序产品在VIOS群集“split-brain”场景中生成主子群和辅助子群的情况下，自主地将由第一个VIOS服务的客户迁移到其他VIOS，其中第一个VIOS位于辅助子群集中。集群中的VIOS不断交换保持活动信息，为每个VIOS提供集群内其他VIOS的最新状态，并在一个或多个节点松动连接或不再与其他节点通信时通知VIOS 在集群中，与群集分裂事件/条件一样。当检测到此事件时，第一子集群假设主子集群角色，并且辅助子集群中的一个或多个VIOS所服务的一个或多个客户端会自动迁移到主子集群中的其他VIOS，从而最小化以前由不可用/不通信的VIOS进行的客户停机。

摘要： Hibernation and remote restore functions of a client logical partition (LPAR) that exists within a data processing system having cluster-aware Virtual Input/Output (I/O) Servers (VIOSes) is performed via receipt of commands via a virtual control panel (VCP) through an underlying hypervisor. The client hibernation data file is stored in a shared repository by a source/original VIOS assigned to the client. The hypervisor receives a remote restart command and assigns a target/remote client LPAR and a target VIOS. The source I/O adapters and target I/O adapters are locked and the target VIOS gathers adapter configuration information from the source VIOS and configures the target adapters to be able to perform the I/O functionality provided by the source adapters to the client LPAR. The target VIOS then retrieves the client's hibernation data file, and the client LPAR is restored at the remote LPAR with the target VIOS providing the client's I/O functionality.

摘要： A method 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 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.
摘要翻译：一种方法利用集群感知来有效支持实时分区移动性（LPM）事件，并提供虚拟输入/输出（IOS）服务器（VIOS）集群中的节点故障恢复。 LPM实用程序在启动相应的LPM事件时在第一个VIOS上创建一个监视线程。监控线程跟踪LPM的状态，并将状态信息记录在数据库的移动表中。 LPM实用程序在（同一）源服务器上运行的其他VIOS上创建其他监视线程。如果第一个VIOS VIOS维持多个故障之一，则LPM实用程序会向其他运行的节点/ VIOS提供通知。 LPM实用程序使运行的监视线程更新LPM状态。特别地，最后一个监视线程可以基于在第一服务器上处于故障状态的节点的指示来执行数据库内的清理/更新操作。
