摘要： A method, system, and computer usable program product for addressing a workload partition are provided in the illustrative embodiments. A packet of data directed to the WPAR and including a combined address is received at a software stack. A determination is made whether the combined address includes an identifier that is reserved. If the identifier is not reserved, the identifier is used to identify the WPAR in the data processing system and the packet is sent to the WPAR. The software stack is an application configured to enable data communication using a protocol of the packet, and is modified to detect, recognize, and process the combined address for routing the packet to the WPAR. The combined address may be logically formed using an identifier associated with the data processing system and an identifier associated with the WPAR, which may be located in different portions of the packet.

摘要： A method and system for providing multiple input/output paths for accessing storage devices includes providing two or more logical paths between a virtual I/O client partition and a storage device and establishing a physical path between the virtual I/O client partition and the storage device by assigning the storage device to a first logical path of the two or more logical paths. The method further includes reestablishing the physical path by dynamically assigning the storage device to a second logical path of the two or more logical paths in an event of unavailability of the first logical path.

摘要： With N_Port ID Virtualization (NPIV), a managed system can be configured so that multiple logical partitions (LPARs) can access independent physical storage through the same physical fiber channel adapter. An NPIV client recovery component of a virtualization management component, such as a Power Hypervisor (pHYP), provides the emulation mapping between server and client virtual fiber channel adapters. The pHYP also provides a mechanism that prevents client partition crashes when the NPIV server (e.g., a VIOS logical partition) goes down. When the NPIV server is rebooted or powers down, the pHYP handles the client LPARs to avoid a crash by removing processing resources from the client logical partition. Thereby, the client logical partition is prevented from attempting to access a root volume group in physical storage via the NPIV server. The pHYP allocates processor resources to the client LPAR when the NPIV server is again available for I/O processing.
摘要翻译：使用N_Port ID虚拟化（NPIV），可以配置受管系统，以便多个逻辑分区（LPAR）可以通过相同的物理光纤通道适配器访问独立的物理存储。虚拟化管理组件（例如Power Hypervisor（pHYP））的NPIV客户端恢复组件提供服务器和客户端虚拟光纤通道适配器之间的仿真映射。 pHYP还提供了一种机制，可防止NPIV服务器（例如，VIOS逻辑分区）故障时客户端分区崩溃。当NPIV服务器重新启动或关闭电源时，pHYP通过从客户机逻辑分区中删除处理资源来处理客户端LPAR以避免崩溃。因此，客户端逻辑分区被阻止经由NPIV服务器试图访问物理存储器中的根卷组。当NPIV服务器再次可用于I / O处理时，pHYP将处理器资源分配给客户端LPAR。

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.

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： 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.
