摘要： Provides a method for increasing the connectivity of I/O resources to a multiplicity of operating systems (OSs) running in different resource partitions of a computer electronic complex (CEC) to obtain sharing of the I/O resources among the OSs of the CEC, including channels, subchannels (devices), and control units (CUs). The invention provides image identifiers (IIDs) for assigning resources to the different OSs. Each shared I/O resource has a sharing set of control blocks (CBs) in which a respective CB is assigned to (and located by) a respective IID of one of the OSs. Each of the CBs in a sharing set provides a different image of the same I/O resource. The different CB images are independently set to different states by I/O operations for the different OSs, so that the OSs can independently share the same I/O resource.

摘要： Enables any OS of plural OSs within any of plural logical-resource partitions (LPARs) of a CEC to use interpretive execution for synchronously-executable CHSC (channel subsystem call) commands. A CHSC command authorization mask (CCAM) is provided to control which CHSC commands are allowed to execute interpretively (with pass-through), and which commands are executed with hypervisor intervention (as all prior CHSC commands did). By enabling interpretive execution of those commands which can successfully operate with pass-through, significant system efficiency is obtained. And by disabling interpretive execution for a subset of CHSC commands (which are not allowed to execute with pass-through) potential system failures may be prevented. Thus, interpretive execution may be restricted differently among the OSs in a CEC. Novel CHSC command execution now handles multiple images of shared I/O resources by use of image identifiers, which could not be done before. The information requested by any OS issuing a CHSC command is filtered and optionally compacted by the I/O subsystem responding to the command by only providing information obtained from control blocks associated with the OS which issued the command. This is done by having a set of control blocks for each I/O resource, each control block in the set being associated with a particular OS.
摘要翻译：使CEC的多个逻辑资源分区（LPAR）中的任何一个中的多个OS的任何OS能够使用用于同步可执行CHSC（信道子系统调用）命令的解释性执行。提供了一个CHSC命令授权掩码（CCAM）来控制哪些CHSC命令被解释性地执行（具有传递），以及哪些命令由管理程序干预执行（如所有之前的CHSC命令所执行）。通过启用能够通过直通成功运行的命令的解释执行，可以获得显着的系统效率。并且通过禁止CHSC命令的子集（不允许通过执行）的解释执行，可能会阻止潜在的系统故障。因此，CEC中的操作系统之间的解释性执行可能会受到不同的限制。新的CHSC命令执行现在通过使用以前无法完成的图像标识符处理共享I / O资源的多个映像。由发出CHSC命令的任何OS请求的信息被I / O子系统过滤并且可选地通过I / O子系统来响应该命令，仅提供从与发出该命令的OS相关联的控制块获得的信息。这通过为每个I / O资源设置一组控制块来实现，该集合中的每个控制块与特定OS相关联。

摘要： This invention involves reconfiguration support for shared I/O resources in a a computer electronic complex (CEC) supporting both shared and unshared I/O channels of the type described and claimed in U.S. patent application Ser. No. 07/898,867 (PO9-92-016) filed on the same day as the subject application and assigned to the same assignee as the subject application. Prior channel subsystem call (CHSC) instructions cannot execute when a channel is to be configured as shareable by plural operating systems in a CEC.
