摘要： A unique device name is assigned to each of a plurality of shared storage devices in a cluster configuration database defining membership of nodes in a cluster. A particular node among the nodes defined by the cluster configuration database as a member of the cluster searches the cluster configuration database for a device identifier matching a device identifier of a shared storage device hosted by the particular node. In response to finding a matching device identifier in the cluster configuration database, the particular node renames, in a local configuration maintained at the particular node, a storage device associated with the matching device identifier with the unique name assigned to that storage device in the cluster configuration database.

摘要： A first of a plurality of virtual operating system instances requests a device identifier for a device to be configured by the first virtual operating system instance within an execution space of the first virtual operating system instance. In response, a device identifier data structure maintained in a kernel space is accessed, and a device identifier that is available is determined. An indication in the device identifier data structure that the device identifier is no longer available is recorded. The device identifier is returned from the kernel space to the first virtual operating system instance. The first virtual operating system instance assigns the device identifier to the device.

摘要： System timers set by a central processing unit (CPU) provide a variable wait time functionally adapted and related to peripheral device availability. Wait time is iteratively and dynamically adjusted to more closely match peripheral performance to the system, thereby reducing CPU load and enhancing data throughput, with the data output routine executing at a process level rather than an interrupt level.In a preferred embodiment, the prior wait time is cumulated during which the peripheral is unavailable for data in order to form a running average delay utilized as a starting point for a next data input. Large delays are weighted to avoid skewing average wait time too quickly for infrequent longer events. Data throughput is thereby increased, avoiding unnecessary dormant periods with no output from the system, while, at the same time, CPU loading is reduced by avoiding excessive system polling.

摘要： An OS instance can maintain management responsibility for SAN adapters to ensure separation and isolation of WPARs, while WPARs are given the capability of configuring an adapter (e.g., adding endpoint storage devices to the adapter). An operating system instance allocates an adapter to a first of a plurality of virtual operating system instances. The first virtual operating system instance updates a device data structure with an entry that indicates the adapter. The first virtual operating system instance maintains the device data structure. The first virtual operating system instance modifies the entry in the device data structure to associate a set of one or more endpoint storage devices with the adapter. The set of endpoint storage devices are provisioned to the first virtual operating system instance from a storage area network. The first virtual operating system instance configures the set of endpoint storage devices.

摘要： A method and system for assigning non-conflicting bus resources to a plurality of devices connected to that bus. The system provides for resolution of resources for all devices attached to the bus or for just a subset of the devices attached to the bus. The system provides for special types of relationships between bus resources; "grouped" resources allow a device to control the selection of a value for one resource based on the value of a different resource, and "shared" resources allow two or more different devices to share a single bus resource. First, a list of the devices attached to the bus is constructed, and for each device a list of the device's bus resources (attributes) is also constructed. The system then prunes unusable bus resource values from the attribute lists, based on what is allowed by the particular machine and bus to which the device is connected. The system then begins a search to find the first non-conflicting solution which will resolve each device in the device list in turn. If a device is determined to be irresolvable at any stage then the system continues to attempt to resolve any remaining devices. Some devices may share interrupt levels with other devices; this system attempts to assign unique and non-conflicting bus resources for all devices, but if a unique interrupt level assignment may not be made the system will attempt to find a suitable "shareable" interrupt level currently assigned to another device which may also be assigned to the first device.
摘要翻译：一种用于将非冲突总线资源分配给连接到该总线的多个设备的方法和系统。该系统为连接到总线的所有设备或仅连接到总线的设备的子集提供资源的分辨率。该系统提供公共汽车资源之间的特殊类型的关系; “分组”资源允许设备基于不同资源的值来控制对一个资源的值的选择，并且“共享”资源允许两个或多个不同的设备共享单个总线资源。首先，构建附加到总线的设备的列表，并且对于每个设备，还构建设备的总线资源（属性）的列表。系统根据设备所连接的特定机器和总线所允许的内容，从属性列表中删除不可用的总线资源值。然后，系统开始搜索以找到将依次解析设备列表中的每个设备的第一个非冲突解决方案。如果设备在任何阶段被确定为不可取消，那么系统将继续尝试解决剩余的任何设备。某些设备可能与其他设备共享中断级别; 该系统尝试为所有设备分配唯一和非冲突的总线资源，但是如果不能进行唯一的中断级别分配，则系统将尝试找到当前分配给另一个可能被分配的另一个设备的合适的“可共享”中断级别到第一个设备。
