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： With N_Port ID Virtualization (NPIV), a managed system can he configured so that multiple logical partitions (LPARs) can access independent physical storage through the same physical fibre 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 fibre 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： Mechanisms are provided for detecting changes in virtual storage device configurations. The mechanisms detect an event corresponding to a change in configuration of a virtual storage device. The virtual storage device is comprised of a plurality of portions of a plurality of physical storage devices. The mechanisms further, in response to detecting the event, determine if the change in configuration of the virtual storage device results in a change in the types of physical storage devices that are part of the virtual storage device. Moreover, the mechanisms further transmit a notification, in response to a determination that the change in configuration of the virtual storage device results in a change in the types of physical storage devices that are part of the virtual storage device, of the results of the change in configuration of the virtual storage device to one or more registered recipients registered to receive such notifications.

摘要： Automated paging device management is provided for a shared memory partition data processing system. The automated approach includes managing a paging storage pool defined within one or more storage devices for holding logical memory pages external to physical memory managed by a hypervisor of the processing system. The managing includes: responsive to creation of a logical partition within the processing system, automatically defining a logical volume in the paging storage pool for use as a paging device for the new logical partition, the automatically defining occurring absent use of a filesystem, with the resultant paging device being other than a file in a filesystem; and automatically specifying the logical volume as a paging space device for the new logical partition and binding the paging space device to the new logical partition, wherein the logical volume is sized to accommodate a defined maximum memory size of the new logical partition.

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.
