摘要： Embodiments that dynamically manage physical and virtual multipath I/O are contemplated. Various embodiments comprise one or more computing devices, such as one or more servers, having at least two HBAs. At least one of the HBAs may be associated with a virtual I/O server that employs the HBA to transfer data between a plurality of virtual clients and one or more storage devices of a storage area network. The embodiments may monitor the availability of the HBAs, such as monitoring the HBAs for a failure of the HBA or a device coupled to the HBA. Upon detecting the unavailability of one of the HBAs, the embodiments may switch, dynamically, from the I/O path associated with the unavailable HBA to the alternate HBA.

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。

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.
摘要翻译：在具有多个虚拟操作系统（OS）分区的数据处理系统中，通过在虚拟机上执行群集感知（CA）OS，在OS分区内提供第一群集感知虚拟输入/输出服务器（VIOS）处理器资源的第一个VIOS。 CA OS通过将第一个VIOS与包含第二个VIOS的VIOS集群进行注册，将VIOS建立为群集感知VIOS。将第一个VIOS注册到VIOS群集可使第一个VIOS接收VIOS群集配置数据和状态数据，这为VIOS提供了VIOS群集中其他VIOS的信息。因此，第一个VIOS能够与VIOS群集内的其他VIOS通信，并与VIOS群集中的其他VIOS共享I / O资源。相关的集群信息存储在第一个VIOS的本地存储器中。

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.
摘要翻译：一种方法在数据处理系统内提供输入/输出（I / O）冗余，其具有（a）产生和消耗I / O请求的客户端逻辑分区（LPAR），（b）多个虚拟输入/输出服务器），其彼此通信地相互连接以形成VIOS群集，并且其包括用于连接到提供对块存储的访问的架构的虚拟I / O适配器。在一个实施例中，第一VIOS从客户机LPAR接收I / O请求。第一个VIOS检测到与块存储器的结构连接存在问题，并且第一个VIOS通过自主地将I / O请求传播到第一个VIOS连接到的第二个VIOS来响应检测到的连接问题。 I / O请求转发到块存储随后由第二个VIOS完成。
