摘要： A communication port of a communications interface of an information handling system comprises a plurality of virtual ports. A first command is issued to obtain information indicating a number of images of virtual ports supportable by the communications interface. A second command is then issued requesting the communications interface to virtualize the communication port. In response to the second command, one or more virtual switches are then configured to connect to the communication port, each virtual switch including a plurality of virtual ports, such that the one or more virtual switches are configured in a manner sufficient to support the number of images of virtual ports indicated by the obtained information. Thereafter, upon request via issuance of a third command, a logical link is established between one of the virtual ports of one of the virtual switches and a communicating element of the information handling system.

摘要： Method and means to provide a mechanism by which a hypervisor can permit a real machine to interpretively execute certain I/O instructions independently of the value of an I-bit in the subchannel. This is necessary as the I-bit covers all I/O instructions that can be interpretively executed; however, there can be instances where the hypervisor cannot allow the interpretive execution of other I/O instructions but can permit the interpretive execution of the SIGA instruction.
摘要翻译：提供一种机制，其中管理程序可以允许真实机器独立于子通道中的I位的值来解释性地执行某些I / O指令。这是必要的，因为I位覆盖可以解释性执行的所有I / O指令; 然而，可能存在虚拟机管理程序不能允许解释执行其他I / O指令但可以允许解释执行SIGA指令的情况。

摘要： An input/output subsystem is configured as a plurality of input/output subsystem images, each of which appears to a program as an independent input/output subsystem. An input/output subsystem image is identified by an input/output subsystem image identifier, which is used by various programs to designate the particular input/output subsystem image for which an I/O operation is to be performed. An input/output subsystem image includes, for instance, one or more input/output paths. An input/output path of an input/output subsystem image is identified by an input/output path identifier, as well as a physical input/output path identifier.

摘要： Method and apparatus for sending data from one partition to a second partition within a logically partitioned computer. In a data processing system having multiple logical partitions, a send queue is established in the first logical partition, and a receive queue is established in the second logical partition. The send queue is registered in the send queue in a lookup table available to all of the logical partitions. The send queue is registered using as a key the logical partition identification of the first logical partition and the subchannel number (LPAR-ID.SUBCHANNEL#) of the subchannel assigned to the partition. The receive queue is registered in the lookup table using as a key, the internet protocol address of the receive queue in the second partition. A send instruction from the first logical partition is executed which interrogates the lookup table using the LPAR-ID.SUBCHANNEL# key to locate the send queue and IP address key to locate the receive queue, and sends the data in the send queue in the first logical partition to the receive queue in the second logical partition. This method and apparatus provides that discrete servers may be used in each logical partition, and data may be transferred between while maintaining security between the logical partitions.
摘要翻译：将数据从一个分区发送到逻辑分区计算机内的第二分区的方法和装置。在具有多个逻辑分区的数据处理系统中，在第一逻辑分区中建立发送队列，并且在第二逻辑分区中建立接收队列。发送队列在可用于所有逻辑分区的查找表中的发送队列中注册。使用分配给分区的子信道的第一逻辑分区和子信道号（LPAR-ID.SUBCHANNEL＃）的逻辑分区标识作为密钥来注册发送队列。接收队列使用密钥（在第二分区中的接收队列的因特网协议地址）登记在查找表中。执行来自第一逻辑分区的发送指令，其使用LPAR-ID.SUBCHANNEL＃密钥查询查找表来定位发送队列和IP地址密钥以定位接收队列，并且在第一逻辑分区中发送数据在发送队列中逻辑分区到第二个逻辑分区中的接收队列。该方法和装置提供了可以在每个逻辑分区中使用离散服务器，并且可以在保持逻辑分区之间的安全性的同时传送数据。

摘要： An apparatus, method and program product for sending data to or receiving data from one or more I/O devices in an I/O operation with a main storage controlled by a processor in a data processing system. The apparatus includes a time-of-day (TOD) register for containing a TOD value, a clock for containing a current TOD value, and a summary register having a first condition when any one of said devices requests an I/O operation and a second condition when no devices have an outstanding I/O request, each device having an outstanding I/O request sets the summary register to its first condition only when the summary register is in its second condition, and further places the current TOD value in the TOD register. A checking program determines if a specified time delay has been exceeded between the value in said TOD register and the current TOD for each requested I/O operation. The checking program drives an interrupt to the processor when the specified time delay has been exceeded.
